COURT OF APPEAL, FOURTH APPELLATE DISTRICT

STATE OF CALIFORNIA

STAHL LAW FIRM et al,

Plaintiffs, Cross-defendants and 

Appellants,

v.

APEX MEDICAL TECHNOLOGIES, 

INC., et al.,

Defendants, Cross-complainants

and Appellants.

 D072906

 (Super. Ct. No. 37-2010-

 00097839-CU-CP-CTL)

APPEALS from a judgment of the Superior Court of San Diego County, 

Katherine Bacal, Judge. Affirmed as modified.

Norbert Stahl, in pro. per., for Plaintiffs, Cross-defendants and 

Appellants.

Arthur A. Wellman, Jr. for Defendants, Cross-complainants and 

Appellants.

This appeal arises from a dispute over legal fees and the quality of the 

legal services for which those fees were charged. In 2007 and 2008, I-Flow 

Corporation (I-Flow) filed lawsuits against Apex Medical Technologies, Inc. 

(Apex) and Zone Medical LLC (Zone) alleging patent infringement and trade 

secret misappropriation. Norbert Stahl, the sole attorney for Stahl Law 

Firm, represented Apex and Zone in the litigation. I-Flow prevailed at trial

and, thereafter, the parties negotiated a settlement of the dispute. 

Thereafter, Stahl filed a complaint against Apex, Zone, and a number 

of company officers, including Mark McGlothlin, Alice DePaul, and Michael 

Marasco (collectively, the Zone Defendants) seeking recovery for unpaid legal 

fees related to the I-Flow litigation. The Zone defendants responded with a 

cross-complaint alleging professional malpractice and breach of fiduciary 

duty. After the Zone Defendants presented their affirmative evidence on the 

cross-complaint, the superior court granted a motion for nonsuit on the 

professional malpractice cause of action. At the conclusion of the case, the 

jury found in favor of the Zone defendants on all remaining causes of action

and awarded damages to Zone, Apex, and McGlothlin pursuant to their claim 

for breach of fiduciary duty. 

Stahl appeals from the judgment and asserts the damages awarded to 

Zone, Apex, and McGlothlin must be vacated as a matter of law in light of the 

allegations in the cross-complaint, the superior court’s grant of nonsuit, and 
3

inconsistencies in the special verdict form submitted by the jury. The Zone 

Defendants cross-appeal and argue the superior court erred by granting 

Stahl’s motion for nonsuit on the professional malpractice cause of action. In 

a separately-filed motion, the Zone Defendants ask this court to dismiss

Stahl’s appeal based on the disentitlement doctrine. 

We decline to exercise our discretion under the disentitlement doctrine 

to dismiss Stahl’s appeal. We conclude the superior court did not err by 

granting the motion for nonsuit and that the damages awarded to Apex and 

Zone were appropriate but that the damages awarded to McGlothlin must be 

vacated. 

FACTUAL AND PROCEDURAL BACKGROUND

Underlying Litigation (The Patent Litigation)

McGlothlin and DePaul founded Apex in 1985 and founded Zone in or

around 2007. Apex manufactured an elastomeric infusion pump called the

Solace pump and Zone distributed the pump. I-Flow also manufactured and 

sold elastomeric infusion pumps, and the pumps sold by Apex competed with 

I-Flow’s pumps for market share. 

In late 2006, I-Flow sent a letter to McGlothlin, as president of Apex. IFlow alleged that the Solace pump infringed United States Patent No. 

5,284,481 (the ‘481 Patent), which had been assigned to I-Flow, and 

demanded that Apex immediately stop making, using, or selling the Solace 
4

pump. Apex sent the letter to a patent attorney, Henry Heines. Heines 

conducted an analysis of the ‘481 patent and determined the Solace pump did 

not infringe any claims of the patent. He sent a letter to I-Flow’s attorneys 

containing his analysis. 

On June 29, 2007, I-Flow filed a complaint in the federal district court 

for patent infringement against Apex. Just a few days later, on July 3, Stahl 

sent an unsolicited letter to McGlothlin, as president of Apex, noting the 

complaint filed by I-Flow and offering to represent Apex. In the letter, Stahl 

stated that he was “a patent attorney with over 10 years of experience in 

helping inventors and companies in patent matters in Courts and in the 

Patent Office.” 

In August, Heines provided Apex with a detailed non-infringement 

opinion, in which he concluded that neither the Solace pump nor any of the 

commercial activities associated with it infringed the ‘481 Patent.1 

In September, McGlothlin engaged Stahl to represent Apex and Zone in

patent prosecution related to catheter technology and the Patent Litigation. 

The engagement letter indicated Stahl would charge an hourly rate of $280 

for his services, with a $20 per hour discount for litigation services. 

1 It is common practice for a company or individual threatened with 

patent litigation to obtain such a written opinion of counsel as a basis to 

avoid treble damages based on the willful infringement of the patent. (See 

Halo Electronics, Inc. v. Pulse Electronics, Inc. (2016) 136 S.Ct. 1923, 1935.) 
5

Thereafter, I-Flow named McGlothlin as a defendant in the federal 

lawsuit against Apex and filed a second complaint against Zone. The cases 

were consolidated and I-Flow amended its complaint to add claims for trade 

secret misappropriation, breach of confidence, and unfair competition. 

Specifically, I-Flow alleged that Apex obtained and disclosed I-Flow trade 

secrets. I-Flow also alleged that McGlothlin personally obtained and 

disclosed confidential business information. 

At the conclusion of the trial, in October 2009, the jury found that the 

‘481 Patent was valid and that Apex willfully infringed claims 1, 2, and 15. 

The jury awarded I-Flow nearly $3 million on the patent claims. The jury 

also found that Apex and McGlothlin willfully and maliciously 

misappropriated at least one of I-Flow’s trade secrets, breached I-Flow’s

confidence, and engaged in unfair competition against I-Flow. The jury

awarded approximately $9 million in damages to I-Flow on those claims, with 

the liability split between Apex and McGlothlin.

Litigation Between Stahl and the Zone Defendants (The Malpractice/Fee

Litigation)

The following February, Stahl filed a complaint against the Zone 

Defendants seeking approximately $100,000 in unpaid legal fees. The 

complaint listed the following five causes of action: 1) breach of contract; 2) 

breach of covenant of good faith and fair dealing; 3) quantum meruit for 

services rendered; 4) open book account; and 5) account stated. 
6

The Zone Defendants asserted numerous affirmative defenses and also 

filed a cross-complaint alleging causes of action for professional malpractice 

and breach of fiduciary duty. In the professional malpractice cause of action, 

they alleged that Stahl failed to conduct proper investigation and discovery; 

failed to retain, designate, and prepare appropriate expert witnesses; failed 

to submit complete expert reports; failed to designate relevant witnesses, 

evidence, and transcripts at trial; failed to adequately prepare for trial; and 

abandoned the Zone Defendants on the eve of trial. With respect to the 

breach of fiduciary duty cause of action, the cross-complainants alleged Stahl 

placed his financial interests above those of his clients, the legal fees reflected 

in Stahl’s invoices “were excessive, unreasonable and not consistent with 

actual time devoted to the matter,” and that Stahl abandoned the Zone 

Defendants at a critical stage of the case.

Nonsuit on Professional Malpractice Cross-Claim 

Stahl filed a motion for nonsuit on the claims asserted in the crosscomplaint at the outset of the trial. He asserted that the Zone Defendants 

could not prove causation of damages because they had not designated a 

number of witnesses or exhibits from the Patent Litigation and, therefore,

could not prove that the outcome of the case would have been different but for 

Stahl’s alleged errors. The Zone Defendants responded that they could prove 

causation without putting on all of the evidence from the Patent Litigation by 
7

presenting testimony that was not presented in the underlying trial and 

opinions regarding whether that testimony would have changed the outcome

of the Patent Litigation. 

The superior court found that there was no evidence to show a breach 

of confidentiality and no allegation in the cross-complaint that Stahl 

represented another party with a conflicting interest and granted the nonsuit 

with respect to those issues only. The court denied the motion in all other 

respects based on the Zone Defendants’ assertion that they intended to 

present evidence sufficient to support each element of their asserted claims. 

The court noted that the denial was without prejudice and that Stahl could 

bring the motion again at the conclusion of the cross-complainants’ case, at 

which point the court would be able to decide whether the Zone Defendants 

had presented sufficient evidence to defeat Stahl’s nonsuit motion. 

After the Zone Defendants rested their case with respect to the crosscomplaint, Stahl renewed his motion for a nonsuit. Stahl asserted the Zone 

Defendants had not presented sufficient evidence from the Patent Litigation 

to prove that the outcome would have been any more favorable to them but 

for Stahl’s alleged negligence. The Zone Defendants conceded that they had 

not presented all of the evidence that was presented in the Patent Litigation 

but argued that they had established several things would not have 

happened but for Stahl’s negligence and that the jury could determine 
8

whether Stahl’s negligence was a substantial factor in the outcome of the 

underlying case. The superior court concluded the Zone Defendants had not 

presented sufficient evidence to support the causation element of the 

professional malpractice cause of action and granted the nonsuit as to that 

cause of action. 

With respect to the breach of fiduciary duty cause of action, the Zone 

Defendants asserted they had proved they would not have retained Stahl had 

they known his true qualifications, that his fees were not properly earned, 

and that they suffered damage as a result. The court again noted that the 

breach of fiduciary duty cause of action included allegations regarding 

excessive, unreasonable, and inconsistent billing by Stahl. The court 

therefore denied Stahl’s motion as to the breach of fiduciary duty cause of 

action. 

Jury Instruction and Verdict 

With the agreement of both parties, the court instructed the jury 

regarding damages for the breach of fiduciary duty claim as follows:

“If you decide that Apex Medical Technologies, Inc., Zone 

Medical, LLC, and/or Mark McGlothlin has proved its or 

his claim against Norbert Stahl, you must also decide how 

much money will reasonably compensate Apex Medical 

Technologies, Zone Medical, LLC, and/or Mark McGlothlin 

for the harm.· This compensation is called damages.· The 

amount of damages must include an award for each item of 

harm that was caused by Norbert Stahl’s wrongful conduct 
9

even if the particular harm could not have been 

anticipated. 

“Apex Medical Technologies, Inc., Zone Medical, LLC, 

and/or Mark McGlothlin did not have to prove the exact 

amount of damages that will provide reasonable 

compensation for the harm. However, you must not 

speculate or guess in awarding damages.

“The following are the specific items of damages claimed by 

Apex Medical Technologies, Inc., Zone Medical, LLC, and 

Mark McGlothlin:

“Legal fees paid to Norbert Stahl related to the I-Flow 

versus Apex litigation.”

The jury found in favor of the Zone Defendants on all of the claims 

asserted by Stahl and found that Stahl was not entitled to any additional fees

for his work on the Patent Litigation. The jury also found in favor of the Zone 

Defendants on the breach of fiduciary duty cause of action and awarded 

damages in the amount of $156,192.60 to Apex, $52,064.20 to Zone, and 

$312,385.20 to McGlothlin. 

Post-Trial Motions 

Stahl filed a motion for judgment notwithstanding the verdict (JNOV)

and requested a stay of execution of the judgment and a new trial on the 

issue of damages. He argued the damages awarded for breach of fiduciary 

duty must have been based on the outcome of the underlying case rather 

than excessive fees, given the allegations in the cross-complaint and the 

answers the jury submitted on the special verdict form. The Zone Defendants 
10

filed a motion for prevailing party attorney fees and for disgorgement of the 

$520,641.54 in fees that they previously paid to Stahl. 

The superior court found the special verdict form could be reconciled as 

to Apex and Zone. However, the court noted that the jury found that

McGlothlin did not request legal services or have any financial transactions 

with Stahl, concluded that those responses indicated that Stahl did not owe a 

fiduciary duty to McGlothlin, and granted the JNOV with respect to 

McGlothlin. The court ruled that the defendants were the prevailing parties 

and that Apex and Zone were entitled to recover their fees.2 The court noted 

that the amount sought in disgorgement was duplicative of the amount of 

damages awarded by the jury on the breach of fiduciary duty claim and 

denied that request. However, the court deemed the motion to be a motion 

for new trial on the issue of damages and granted the request.

Stahl appealed, and, in a previous opinion, this court determined the 

superior court did not have jurisdiction to grant a new trial on damages and 

2 Stahl separately appealed from the subsequent order awarding 

attorney fees and we address the fee award in more detail in an opinion filed 

concurrently in case number D073155. The Zone Defendants ask us to take 

judicial notice in this case of the superior court’s order awarding fees from the 

record in case number D073155. As that order was issued after the judgment 

that is appealed from here, and because we address the fee award in our 

concurrently filed opinion in case number D073155, we hereby deny the 

request. (See Vons Companies, Inc. v. Seabest Foods, Inc. (1996) 14 Cal.4th 

434, 444, fn. 3 [“Reviewing courts generally do not take judicial notice of 

evidence not presented to the trial court.”].)
11

that the JNOV had been denied by operation of law. (See Stahl Law Firm v. 

Apex Medical Technologies, et al. (Dec. 19, 2016, D068929) [nonpub. opn], 

mod. Jan. 1, 2017.) We affirmed the denial of the JNOV by operation of law

based, in part, on Stahl’s failure to provide a complete record on appeal, and

reversed the superior court’s order granting a new trial on damages. (Ibid.)

The matter was remanded to the superior court and the superior court 

entered a judgment based on the previous verdict, awarding damages in the 

amounts of $156,192.60 to Apex, $52,064.20 to Zone, and $312,385.20 to 

McGlothlin. 

Stahl appeals and the Zone Defendants cross-appeal. 

DISCUSSION

I. Motion to Dismiss

While the appeal was pending, the Zone Defendants filed nearly 

identical motions to dismiss this appeal and the appeal in case number 

D073155 pursuant to the disentitlement doctrine. In their briefing, the Zone 

Defendants also assert that the appeal should be dismissed under the 

disentitlement doctrine.3

3 The Zone Defendants asked for a hearing on this motion, and we 

allowed the parties to address the motion during oral argument on the 

appeals. (See California Rules of Court, rule 8.54, subd. (b)(2).) 
12

A. Relevant Legal Principles Regarding the Disentitlement Doctrine 

The disentitlement doctrine allows an appellate court to use its 

inherent power to dismiss an appeal based on a party’s failure to comply with 

a lower court order. (See Stoltenberg v. Ampton Investments, Inc. (2013) 215 

Cal.App.4th 1225, 1229-1230 (Stoltenberg).) “A party to an action cannot . . . 

ask the aid and assistance of a court in hearing his demands while he stands 

in an attitude of contempt to legal orders and processes of the courts of this 

state.” (MacPherson v. MacPherson (1939) 13 Cal.2d 271, 277 (MacPherson).) 

The doctrine has been applied in a variety of cases, including where a 

judgment debtor has attempted to frustrate or obstruct legitimate efforts of 

the trial court to enforce a judgment. (Stoltenberg, at pp. 1230-1232 

[discussing various cases in which courts dismissed appeals based on the 

disentitlement doctrine].) A formal judgment of contempt is not required. 

(Ibid.) 

That said, “ ‘[a]ppellate disentitlement’ is not a jurisdictional doctrine, 

but a discretionary tool that may be applied when the balance of the 

equitable concerns make it a proper sanction.’ ” (Stoltenberg, supra, 215 

Cal.App.4th at p. 1230.) “ ‘The right to an appeal must not be lightly 

forfeited, and where a doubt exists as to a litigant’s conduct being

contumacious or wilful, an appellate court will tolerate temporarily the acts 

which were disruptive of the judicial process. We always prefer to resolve a 
13

cause on its merits; once the rights of the parties have been determined with 

finality, then the thwarted authority and offended dignity of the court may be 

assuaged with condign sanctions to the extent of the affront.’ ” (Id. at pp. 

1231-1232, quoting Tobin v. Casaus (1954) 128 Cal.App.2d 588, 592-593.) 

B. Analysis 

The Zone Defendants assert that Stahl’s appeal should be dismissed 

because he has continually refused to comply with court orders and raise 

several specific examples to support that assertion. 

1. Failure to Pay Previously Ordered Sanctions

First, the Zone Defendants assert that Stahl was sanctioned for 

misconduct during discovery and failed to pay the sanctions until forced to do 

so by the superior court. The Zone Defendants raised this issue during trial 

and alleged that Stahl was in contempt for having failed to pay the sanctions. 

The superior court clarified that it had not yet made a finding of contempt 

but that it could issue an order to show cause regarding contempt if Stahl did 

not pay the sanctions that day. Stahl provided a check to counsel for the 

Zone Defendants later that day, in court, and counsel for the Zone 

Defendants agreed that the check was sufficient. As the Zone Defendants 

concede, Stahl was not held in contempt and this issue is now resolved. 

Accordingly, this is not a basis for application of the disentitlement doctrine.

(See Stoltenberg, supra, 215 Cal.App.4th at pp. 1231-1232.) 
14

2. Failure to Provide a Current Address 

Next, the Zone Defendants allege that Stahl sold his home and went 

“into hiding” after the judgment was entered, and that he has since disobeyed 

an order of the superior court and the California Rules of Court by failing to 

provide a current address to the superior court or to this court on appeal.

The superior court issued an order on April 12, 2017 requiring Stahl to 

update his physical address with the court. Stahl did not comply with the 

order and, instead, started listing an incomplete address on his filings, both 

in the superior court and in this court. The superior court has noted Stahl’s 

failure to comply with its order but has declined to issue an order to show 

cause or to make a contempt finding. 

In a related argument, the Zone Defendants further assert that Stahl 

filed a stipulation in this court to extend the time to file certain appellate 

briefs with a forged electronic signature. They do not dispute that they 

agreed to the extension but contend that their attorney refused to approve

the stipulation in the form that Stahl provided because Stahl had not 

included a current address as required by the applicable Rules of Court.4

4 The Zone Defendants also seek an order from this court requiring Stahl 

to produce the original signature page in court for inspection and copying in 

accordance with California Rules of court, rule 8.75. We hereby deny that 

request. The stipulation does not contain an original signature submitted 

under penalty of perjury and, therefore, California Rules of court, rule 8.75 is 

not applicable. 
15

The Zone Defendants argue that Stahl stands in contempt of the 

superior court order as a matter of fact since he has not updated his address

and rely on Code of Civil Procedure section 1211 to assert that “[b]eing in 

contempt of court is a factual situation.” We disagree. Code of Civil 

Procedure section 1211 allows for direct adjudication of contempt that occurs 

in a judge’s immediate presence, in which case the judge must recite the facts 

of contempt as they occurred, or for indirect adjudication of the contempt 

based on affidavits. (See Code Civ. Proc., § 1211; Hanson v. Sup. Ct. (2001) 

91 Cal.App.4th 75, 82.) It does not permit an appellate court to decide that 

contempt occurred in the trial court as a factual matter. 

That said, the disentitlement doctrine has been applied in the absence 

of a formal judgment of contempt, particularly where a judgment debtor acts 

to obstruct legitimate efforts to enforce a judgment. (Soltenberg, supra, 215 

Cal.App.4th at p. 1230.) However, cases in which appeals have been 

dismissed typically involve more significant efforts to avoid enforcement, 

including, for example, moving out of the country and refusing to respond to 

post-judgment interrogatories, refusing to deposit money into a trustee 

account as ordered by the court, and refusing to appear despite an 

outstanding bench warrant. (Id. at pp. 1230-1232; Stone v. Bach (1978) 80 

Cal.App.3d 442, 448; MacPherson, supra, 13 Cal.2d at p. 277 [dismissing 

appeal where appellant “wilfully and purposely evaded legal processes and 
16

contumaciously defied and nullified every attempt to enforce the judgments 

and orders of the California courts, including the very order from which he 

seeks relief by this appeal”].) Stahl has not demonstrated a similar level of 

obstruction here.

Thus, while we do not condone Stahl’s refusal to follow the order of the 

superior court to provide a current address, or his refusal to follow the 

California Rules of Court requiring that he provide a current mailing address 

to this court and that he include a current mailing address on the cover of 

any document filed with the court, we decline to exercise our discretion to 

dismiss the appeal on this basis. (See Soltenberg, supra, 215 Cal.App.4th at 

p. 1230; see also Cal. Rules of Court, rules 8.32, subd. (b)(1) and 8.40, subd. 

(b)(1).) 

3. The San Mateo Proceedings

The Zone Defendants include significant details in their motion to 

dismiss and the associated appendix about proceedings in the superior court 

in San Mateo, and a related appeal in the first appellate district, in which 

they sought to enforce the judgment, and assert these proceedings are further 

evidence of Stahl’s attempts to evade the judgment. 

Stahl asserts we should not consider these materials as they were not 

before the lower court. However, motions may be based on matters outside 

the record and may be supported by declarations and other supporting 
17

materials. (See Cal. Rules of Court, rule 8.54, subd. (a)(1); Norco Delivery 

Service, Inc. v. Owens Corning Fiberglas Inc. (1998) 64 Cal.App.4th 955, 961, 

fn. 3.) 

Regardless, though, the materials related to the San Mateo proceedings 

do not establish any failure by Stahl to comply with a court order. The 

appellate court there ultimately determined that the trial court erred by 

ordering Stahl to appear without adequately establishing jurisdiction, and 

the Zone Defendants concede that the trial court subsequently vacated its 

previous order requiring Stahl to appear for examination. Accordingly, even 

if we were to consider those materials, they do not provide a basis for 

application of the disentitlement doctrine. (See Stoltenberg, supra, 215 

Cal.App.4th at pp. 1229-1230.) 

4. Mischaracterization of the Record

As a final matter, the Zone Defendants assert that Stahl has 

continually mischaracterized the record, in the superior court and on appeal. 

As an attorney, Stahl has duty of candor to the court which precludes him 

from making false statements of fact or law. (See Prof. Conduct, Rule 3.3; 

Bus. & Prof. Code, § 6106.) A violation of that duty may result in sanctions 

or a referral to the state bar for disciplinary proceedings. (See Bryan v. Bank 

of America (2001) 86 Cal.App.4th 185, 194 (Bryan) [concluding sanctions in 

the form of attorney fees were the appropriate consequence for counsel’s 
18

misrepresentations]; In the Matter of Maloney and Virsik (Review Dept. 2005) 

4 Cal. State Bar Ct. Rptr. 774, 786.) 

Here, the Zone Defendants assert Stahl made false statements to the 

court in the San Mateo proceedings and falsely indicated that he had consent 

from opposing counsel to file the stipulation to extend the time to file briefs. 

As discussed, ante, we decline to dismiss the appeal based on the San Mateo 

proceedings or Stahl’s filing of the stipulation. 

In addition, the Zone Defendants assert Stahl has repeatedly 

mischaracterized the record in his briefing on appeal. To support their 

argument, they cite to a section of Stahl’s opening brief in which Stahl argues 

the Zone Defendants admitted that they spied on and copied from I-Flow in 

the Patent Litigation. In that section of his brief, Stahl includes an excerpt 

from a post-trial motion submitted by I-Flow (hereinafter, exhibit 293) in 

which I-Flow argued it presented evidence of deliberate copying by the Zone 

Defendants at trial in the Patent Litigation. He explains that exhibit 293 is a 

post-trial motion submitted by I-Flow in the Patent Litigation and asserts 

that it was admitted at trial in the Malpractice/Fee Litigation. The Zone 

Defendants assert that the I-Flow document was admitted in the 

Malpractice/Fee Litigation only for the limited purpose of showing what IFlow’s allegations were and implies that Stahl is misrepresenting the record

by suggesting that exhibit 293 proves that the Zone Defendants actually 
19

admitted to copying. We do not read Stahl’s brief as misrepresenting the 

nature of exhibit 293. Regardless, even if we did, this is a dispute over the 

legal significance of exhibit 293; it is not a material misrepresentation of the 

record warranting dismissal of the appeal. 

The Zone Defendants do not identify any other material 

misrepresentations, nor have they pursued a motion for sanctions based on 

any such misrepresentations.5 (See Bryan, supra, 86 Cal.App.4th 185 at p. 

194.) 

We therefore decline to dismiss the appeal under the disentitlement 

doctrine.

II. Appeal and Cross-Appeal

Stahl argues the damages awarded to Apex, Zone, and McGlothlin 

must be reversed as a matter of law as they are inconsistent with the 

allegations in the cross-complaint, the superior court’s grant of nonsuit, and 

the special findings of the jury. In their cross-appeal, the Zone Defendants 

argue that the superior court erred in granting Stahl’s motion for nonsuit and 

by limiting the testimony of their expert on damages. We address the issues 

5 We note that the superior court reported Stahl to the California State 

Bar based on the jury’s finding that he breached his fiduciary duty to the 

Zone Defendants. 
20

raised in the cross-appeal first, as the nonsuit ruling directly impacts the 

scope of recoverable damages. 

A. The Superior Court Did Not Err by Granting Stahl’s Motion for 

Nonsuit on the Professional Malpractice Cause of Action 

1. Relevant Legal Principles 

In cases in which the “ ‘negligence resulted in the plaintiff’s loss of the 

prior lawsuit, the plaintiff must establish: (1) the professional was negligent 

in the handling of the prior lawsuit; (2) the professional’s negligence was a 

substantial factor in the plaintiff’s loss of the prior lawsuit; and (3) the proper 

handling of the prior lawsuit by the professional would have resulted in a [ ] 

judgment in plaintiff’s favor.’ ” (See Mattco Forge, Inc. v. Arthur Young & Co. 

(1997) 52 Cal.App.4th 820, 844 [emphasis added].)

As the California Supreme Court has explained: 

“In a litigation malpractice action, the plaintiff must 

establish that but for the alleged negligence of the 

defendant attorney, the plaintiff would have obtained a 

more favorable judgment or settlement in the action in 

which the malpractice allegedly occurred. The purpose of 

this requirement, which has been in use for more than 120 

years, is to safeguard against speculative and conjectural 

claims. [citation] It serves the essential purpose of 

ensuring that damages awarded for the attorney’s 

malpractice actually have been caused by the malpractice. 

[citation]” (Viner v. Sweet (2003) 30 Cal.4th 1232, 1241 

(Viner), citing Mattco, supra, 52 Cal.App.4th at pp. 832-

834.) 
21

The method for proving causation of damages in such cases, where the

attorney is accused of losing the client’s legal claim or defense, is often 

referred to as putting on a “ ‘trial within a trial’ ” or a “ ‘case within a case’ ”

(Viner, supra, 30 Cal.4th at p. 1240, fn. 4; Mattco, supra, 52 Cal.App.4th at 

pp. 832-833; Ambriz v. Kelegian (2007) 146 Cal.App.4th 1519, 1531.) It is not 

necessary that the plaintiff present all of the evidence from the underlying 

action, but it is necessary that the plaintiff put forth sufficient evidence to 

prove that the lawyer’s errors were the cause of the less than favorable 

outcome or, conversely, that the plaintiff would have received a more 

favorable outcome absent those errors. (See Mattco, at pp. 831-832, 837; 

Piscitelli v. Friedenberg (2001) 87 Cal.App.4th 953, 973 (Piscitelli).) By 

contrast, the method for proving causation in cases arising from transactional 

matters, where there was no trial, may be described as a “ ‘no deal’ ” or 

“ ‘better deal’ ” scenario. (Viner, supra, 30 Cal.4th at p. 1240, fn. 4.) In both 

types of cases, “the crucial causation inquiry is what would have happened if 

the defendant attorney had not been negligent.” (Id. at p. 1242.) 

In some cases, expert testimony is essential to establish the causal link 

between the alleged misconduct and the resulting damages. (4 Mallen, Legal 

Malpractice (2020 ed.) § 37:125 (Mallen).) Evidence or testimony that the 

lawyer was negligent, without more, may not be sufficient to allow the jury to 

determine what the result would have been in the absence of that negligence.

(Ibid.; see also Viner, supra, 30 Cal.4th at p. 1242; Orrick Herrington & 

Sutcliffe v. Sup. Ct. (2003) 107 Cal.App.4th 1052, 1057 (Herrington) [“Simply 

showing the attorney erred is not enough.”].) In cases where the causal link 

is not obvious or established by other evidence, expert testimony may be 

necessary to prove what a competent lawyer would have done differently and

how the alleged negligence proximately caused the injury. (Mallen, at 

§ 37:125; cf. Piscitelli, supra, 87 Cal.App.4th at pp. 971-973 [expert may not 

directly testify as to the ultimate result of the underlying case].) 

To determine whether the superior court erred by granting Stahl’s 

motion for nonsuit on the legal malpractice cause of action in this case, we 

must determine whether the Zone Defendants presented substantial 

evidence, including any expert testimony, from which the jury could have 

concluded that the outcome of the Patent Litigation would have been more 

favorable to them absent Stahl’s negligence. (See Stanley v. Richmond (1995) 

35 Cal.App.4th 1070, 1086 (Stanley); Carson v. Facilities Development Co. 

(1984) 36 Cal.3d 830, 839 [discussing the standard of review for a nonsuit 

ruling].) In making that determination, we may not weigh the evidence or 

consider the credibility of witnesses. (Stanley, at p. 1086.) We accept as true 

the evidence most favorable to the Zone Defendants, indulge all legitimate 

inferences which may be drawn from that evidence, and disregard any 

conflicting evidence. (Ibid.; see also Viner v. Sweet (2004) 117 Cal.App.4th 
23

1218, 1226 (on remand) (Viner II) [trial court erred by denying a JNOV based 

on causation where “the Viners presented no evidence at all, substantial or 

otherwise, indicating that, but for [the lawyers’] negligence, it was more 

likely than not they would have obtained a more favorable result”].) 

2. Evidence Presented at Trial Relevant to the Malpractice Claim 

We begin our analysis with a summary of the evidence presented at 

trial in the Malpractice/Fee Litigation with respect to the professional 

malpractice cause of action. 

a. Evidence Presented by the Zone Defendants 

Company officers McGlothlin, Marasco, and DePaul each testified 

regarding their roles in the companies, the underlying litigation, and Stahl’s 

representation. 

McGlothlin said he believed the value of Stahl’s work was “negative millions 

of dollars” because Stahl took away the opportunity to get alternate trial 

counsel with adequate experience. 

Emil Soika, the named inventor on the ‘481 patent, explained his 

background and his role in discovering the inventions claimed in the ‘481 

patent. Using the claim construction issued by the court in the Patent 

Litigation, Soika opined that the Solace pump did not infringe any of the 

asserted claims of the ‘481 patent. Soika explained that he testified as a fact 

witness at trial in the Patent Litigation but that he was precluded from 
24

providing his opinion that the Solace pump did not infringe the patent. He

said that he reviewed the patent, the Solace pump, and his prior testimony

before testifying in the Malpractice/Fee Litigation, but that he did not review 

the testimony of the other experts, including Richard Meyst, the noninfringement expert that did testify on behalf of the Zone Defendants in the 

Patent Litigation. 

Henry Heines was designated as an expert in patent law, allegations of 

infringement, and claim construction pursuant to 35 U.S.C. section 112, 

paragraph 6,6 and testified regarding his analysis of the ‘481 patent. He

discussed the non-infringement opinion he provided to McGlothlin at the 

outset of the Patent Litigation and stated that he did not speak with Stahl at 

any point prior to the trial in the Malpractice/Fee Litigation. Like Soika, 

Heines did not review any of the materials from the trial in the Patent 

Litigation and did not offer any opinions regarding the outcome of the case. 

Perry De Fazio was designated as an expert witness regarding 

competitive intelligence in the field of medical devices and, specifically, I6 At the time of the patent litigation, 35 U.S.C. section 112, paragraph 6 

(now 35 U.S.C. section 112 (f)), defined a particular type of patent claim often 

referred to as a “means plus function” claim. These types of claims allow the 

patentee to describe a physical element of an invention by describing the 

precise function that the element (the “means”) performs, as opposed to the 

more traditional method of describing the precise physical structure 

necessary to perform the function. (See Biomedino, LLC v. Waters Techs. 

Corp. (Fed.Cir. 2007) 490 F.3d 946, 947.) 
25

Flow infusion pumps in the Patent Litigation. At trial in the Malpractice/Fee 

Litigation, he explained the work he did locating information about the trade 

secrets that I-Flow had alleged and testified that he submitted an expert 

report in the Patent Litigation, but that he ultimately was not permitted to 

share his opinions with the federal jury. He opined that the trade secrets 

alleged by I-Flow were not confidential. He could not recall the specifics of 

the alleged trade secrets but believed the focus was on sales and marketing, 

as opposed to the technical aspects of the product. 

Matthew Murphey, an attorney, was designated as an expert in patent 

litigation and the standard of care appropriate for attorneys in California 

practicing patent litigation. He opined as to the following breaches of the 

standard of care by Stahl: (1) Stahl improperly solicited business from Apex 

and Zone by misrepresenting his own qualifications and background ; (2)

Stahl failed to comply with the patent local rules and the relevant standard 

of care by failing to identify certain claims as means plus function claims 

pursuant to 35 U.S.C. section 112, paragraph 6 ; (3) Stahl failed to designate 

Soika and Heines as experts in the Patent Litigation; (4) Stahl failed to 

provide a complete expert report for De Fazio, which caused the court in the 

Patent Litigation to limit the scope of his testimony ; and (5) Stahl’s invoices

included excessive hours for certain tasks. On cross-examination, Murphey 

confirmed that he did not attend the trial in the Patent Litigation, did not 
26

review the entire record, and did not have knowledge regarding any expert 

witnesses presented by the Zone Defendants other than Soika, Heines, and 

DeFazio. 

Finally, Robert Wallace, a CPA, was designated to testify as to the

damages caused by the breaches of the standard of care identified by 

Murphey. Before Wallace took the stand, Stahl pointed out that Wallace’s

testimony should be limited in accordance with that designation and the 

court stated that it expected Wallace to opine as to the damages caused by 

the breaches of the standard of care identified by Murphey. 

Wallace testified that he understood that Apex and Zone were 

precluded from selling the Solace pump as a result of their loss in the Patent 

Litigation. He then stated that he calculated lost profits based on the 

assumption that the Zone Defendants would not have lost the Patent 

Litigation absent Stahl’s errors. Stahl objected to any testimony regarding 

the lost profits that Wallace calculated based on that assumption as beyond 

the scope of Wallace’s designation. On the same basis, Stahl also objected to 

questions asking Wallace to assume the Zone Defendants would not have 

reached the settlement they did if the results of the Patent Litigation had 

been different. The superior court sustained the objections, thereby 

precluding Wallace from offering any testimony based on the assumption that 
27

the outcome of the Patent Litigation would have been different but for Stahl’s 

errors.

Ultimately, Wallace was able to testify that Stahl billed a total of 

$624,107 for his work on the Patent Litigation, and the Zone defendants paid 

Stahl a total of $520,642. 

b. Evidence Presented by Stahl

Stahl testified on his own behalf and explained that he disclosed and 

produced the non-infringement opinion prepared by Heines in the Patent 

Litigation, but that he intentionally designated Meyst to testify as a noninfringement expert instead of Soika. In addition, he designated another 

expert, Jeffrey Charlton, to testify regarding the technical trade secrets 

alleged by I-Flow, including dip molding methods. 

Neither Meyst nor Charlton testified in the Malpractice/Fee Litigation. 

3. Analysis 

As the superior court concluded, the Zone Defendants failed to make a 

prima facie showing on causation because they did not present sufficient 

evidence from which the jury could conclude that the outcome of the Patent 

Litigation would have been more favorable to them absent Stahl’s negligence. 

(See Viner, supra, 30 Cal.4th at p. 1241.) 

a. The Testimony of Soika, Heines and DeFazio Was Not 

Sufficient to Establish the Zone Defendants Would Have 

Prevailed in the Patent Litigation Absent Stahl’s Errors 
28

The Zone Defendants contend, as they did at trial, that they presented 

evidence sufficient to prove causation because they presented expert 

testimony, not presented in the Patent Litigation, that they did not infringe 

the ‘481 patent and did not use or disclose any of I-Flow’s trade secrets. 

Specifically, at trial in the Malpractice/Fees Litigation, the Zone 

Defendants asserted, and Murphey opined, that Stahl committed professional 

malpractice in the Patent Litigation by failing to designate and/or adequately 

disclose the expert opinions of Soika, Heines, and De Fazio. As a result, 

Soika, Heines, and De Fazio were precluded from presenting all of their 

opinions at trial in the Patent Litigation. Soika, Heines, and De Fazio then 

presented the opinions that were allegedly excluded in the Patent Litigation. 

Soika and Heines testified that the Zone Defendants did not infringe the ‘481 

patent, and DeFazio testified that the Zone Defendants could not have 

misappropriated I-Flow’s alleged trade secrets were not actually secret. 

The Zone Defendants assert this evidence was sufficient to allow the 

jury to conclude that Stahl’s errors were a substantial factor in causing the 

harm they suffered as a result of the verdict in the Patent Litigation, but it 

was not. (See Viner, supra, 30 Cal.4th at pp. 1241-1242.) Inherent in the 

Zone Defendant’s assertion is an assumption that they would have prevailed 

in the Patent Litigation if Soika, Heines, and De Fazio had presented the 
29

same testimony there as they did in the Malpractice/Fee Litigation. That 

assumption, however, is both erroneous and unsupported by the evidence.

It is undisputed that Stahl designated several other expert witnesses in 

the Patent Litigation. At least two of those experts testified at trial in the 

Patent Litigation on behalf of the Zone Defendants and in defense of both the 

patent infringement and trade secrets claims. However, the Zone Defendants 

did not present any evidence at trial in the Malpractice/Fee Litigation 

regarding the testimony of those other experts. In addition, Murphey, the 

Zone Defendants’ expert on Stahl’s breaches of the standard of care, conceded 

that he did not review the entire record from the Patent Litigation and that 

he did not have any knowledge regarding the testimony of the other experts

that did testify. Similarly, Soika and Heines also had not reviewed the 

complete record from the Patent Litigation and, thus, also could not opine on 

the relative impact of their own testimony. 

Without any evidence regarding the opinions offered by the experts 

that did testify in the Patent Litigation, the jury in the Malpractice/Fee 

Litigation had no way to know whether the additional testimony of Soika, 

Heines, and De Fazio would have had any impact on the outcome of the 

litigation. More importantly, the jury had no way to know if there was a void 

in the expert testimony that was presented at trial in the Patent Litigation

that Soika, Heines, and De Fazio would have filled. If, for example, the 
30

experts that did testify in the Patent Litigation offered essentially the same 

opinions that Soika, Heines, and De Fazio offered in the Malpractice/Fee 

Litigation, the testimony of Soika, Heines, and De Fazio would not have 

changed the outcome. Accordingly, the testimony of Soika, Heines, and De 

Fazio was not sufficient, on its own or in combination with Murphey’s 

testimony regarding Stahl’s errors, to support a finding that the Zone 

Defendants would have received a more favorable outcome in the Patent 

Litigation absent Stahl’s errors. (See Mattco, supra, 52 Cal.App.4th at pp.

831-832, 837; Piscitelli, supra, 87 Cal.App.4th at p. 973; SiRF Technology, 

Inc. v. Orrick Herrington and Sutcliffe LLP (N.D.Cal., June 22, 2010) 2010 

WL 2560076 at * 12, 16 (SiRF) [evidence regarding supplemental expert 

reports excluded in patent infringement action as a result of alleged legal 

malpractice insufficient to prove causation absent evidence that the outcome 

of the litigation would have been different if the reports had been 

submitted].) 

Moreover, with respect to the trade secret claims, the jury was not 

presented with a detailed description of the alleged trade secrets and De 

Fazio testified that he could no longer recall the specifics of the trade secrets 

he had previously analyzed. Absent evidence regarding the full detailed list 

of alleged trade secrets, there was no way for the jury to determine if De 

Fazio’s additional testimony was sufficient to prove that none of the alleged 
31

trade secrets were actually trade secrets. Thus, as with the other expert 

witnesses, DeFazio’s testimony also was not sufficient to establish a causal 

link between the exclusion of that testimony and the outcome of the Patent 

Litigation. (See Viner, supra, 30 Cal.4th at p. 1241; Herrington, supra, 107 

Cal.App.4th at p. 1057; see also Piscitelli, supra, 87 Cal.App.4th at pp. 971-

973.) 

The Zone Defendants assert that they did not have to put forth every 

item of evidence that was before the jury in the Patent Litigation. We agree 

that the Zone Defendants did not need to put forth all of the evidence from 

the Patent Litigation, but it was nevertheless their burden to put forth 

enough evidence to prove they would have received a more favorable outcome 

in the Patent Litigation absent Stahl’s errors. (See Mattco, supra, 52 

Cal.App.4th at pp. 832, 837; Viner, supra, 30 Cal.4th at p. 1241.) As 

discussed, they failed to do so. 

In a related argument, the Zone Defendants assert Stanley, supra, 35 

Cal.App.4th 1070, relied upon by Stahl, supports their position because the 

court in Stanley did not discuss the case within a case method for proving 

causation. We disagree. The errors in Stanley were related to the drafting of 

a martial settlement agreement (MSA), which is more akin to transactional 

malpractice than litigation malpractice. In Viner, which was decided eight 

years after Stanley, our Supreme Court noted that the phrase “case within a 
32

case” refers to a method for proving causation that is typically used in cases 

alleging litigation, as opposed to transactional, malpractice. (See Viner,

supra, 30 Cal.4th at p. 1240, fn. 4.) Regardless, the Court in Viner confirmed 

that in both types of cases, the plaintiff “must show that but for the alleged 

malpractice, it is more likely than not that the plaintiff would have obtained 

a more favorable result.” (See Ibid. at p. 1244.) As discussed, here the Zone 

Defendants did not establish that they would have obtained a more favorable 

result in the Patent Litigation absent Stahl’s errors. (See Stanley, at 

pp. 1095-1097 [overturning the trial court’s nonsuit ruling after concluding 

Stanley presented sufficient evidence “from which a reasonable trier of fact 

could find [Stanley] was damaged by [her attorney’s negligence]”; Viner, 

supra, 30 Cal.4th at p. 1241 [“It is the failure of the client to establish the 

causal link that explains decisions where the loss is termed remote or 

speculative”].)7 

7 The Zone Defendants also rely on In re Fountain (1977) 74 Cal.App.3d 

715 (In re Fountain) and Slovensky v. Friedman (2006) 142 Cal.App.4th 1518 

(Slovensky), but those cases are not instructive here. In re Fountain was a 

criminal case in which the defendant asserted his right to obtain an appeal 

despite his attorney’s failure to file a timely notice of appeal. (In re Fountain,

at p. 717.) Along with granting the defendant’s writ petition, the court 

ordered that the negligent attorney return all fees paid to him in the 

representation. (Id. at 719.) In Slovensky, the court noted the order in In re

Fountain, but concluded disgorgement of fees was not warranted where the 

attorney’s negligence had caused the client no damages. (Slovensky, at p. 

1535.) 
33

In sum, the Zone Defendants did not present sufficient evidence from 

which the jury in the Malpractice/Fee Litigation could have concluded that

Stahl’s errors were a significant factor in the outcome of the Patent Litigation 

or that they would have received a more favorable verdict in the absence of 

those errors. (See Mattco, supra, 52 Cal.App.4th at p. 840; Viner II, supra, 

117 Cal.App.4th at p. 1226; SiRF, supra, 2010 WL 2560076 at * 12, 16.) As a 

result, the superior court correctly determined that the Zone Defendants did 

not make a prima facie showing on the causation element of the legal 

malpractice cause of action and granted Stahl’s motion for nonsuit as to that 

cause of action. (See Viner II, at p. 1226.)

b. The Zone Defendants Did Not Present Sufficient 

Evidence to Establish a Causal Link Between Stahl’s Claim 

Construction Errors and the Outcome of the Patent 

Litigation

The Zone Defendants also assert they presented evidence that Stahl 

failed to identify certain elements of the asserted claims as means-plusfunction elements, thereby waiving the argument, and that the jury likely 

would not have found that the Solace pump infringed the claim under an 

appropriate claim construction. However, the Zone Defendants failed to 

provide the jury in the Malpractice/Fee Litigation with an alternative claim 

construction that addressed the alleged means-plus-function elements.

Claim construction is a matter of law to be decided by the court and, here, it 
34

is undisputed that the Zone Defendants did not ask the court in the 

Malpractice/Fee Litigation to issue its own claim construction. (See 

Markman v. Westview Instruments (1996) 517 U.S. 370, 390 [claim 

construction is a matter of law for the court, not the jury]; see also New Tek 

Mfg. v Beehner (2005) 270 Neb. 264, 272-274, 276 [concluding claim 

construction, including whether a claim is in a means-plus-function format, is 

a matter of law for the state court to decide in a legal malpractice case].) The 

jury in the Malpractice/Fee Litigation could not determine whether the 

Solace pump would have infringed under an alternate mean-plus-function 

construction that was never provided to them. Therefore, the Zone 

Defendants once again failed to provide sufficient evidence from which the 

jury could conclude that they would have prevailed in the Patent Litigation 

in the absence of Stahl’s error

c. The Zone Defendants’ Remaining Arguments are Not 

Sufficiently Developed or Supported by Citations to the 

Record or Law 

The Zone Defendants raise additional arguments regarding the nonsuit 

ruling in a perfunctory manner and without citation to the record. (See 

Benach v. County of Los Angeles (2007) 149 Cal.App.4th 836, 852 (Benach) 

[“An appellant must provide an argument and legal authority to support his 

contentions”]; Cal. Rules of Court, rule 8.204(a)(1)(C) [briefs must support 

any reference to a matter in the record by citation].) It is the appellant’s 
35

burden to affirmatively demonstrate error. (Fundamental Investment etc. 

Realty Fund v. Gradow (1994) 28 Cal.App.4th 966, 971.) ”It is not our place to 

construct theories or arguments to undermine the judgment and defeat the 

presumption of correctness.” (Benach, at p. 852.) 

Specifically, the Zone Defendants allege “[h]ad Stahl been candid about 

his qualifications, abilities, and the proceedings in the case, he never would 

have been retained, never [would have] been permitted to be solely in charge 

of the case, [would have] been terminated, and would not have been paid.” 

They further allege that, “Had Stahl been candid with his clients, they might 

have taken a settlement offer that would have resulted in a net monetary 

gain, instead of loss”. The Zone Defendants did not present these arguments 

in the superior court, do not develop them in their briefing on appeal, and do 

not provide citations to the record or legal authority to support them. (See 

Benach, supra, 149 Cal.App.4th at p. 852.) Therefore, they have not met 

their burden to affirmatively establish error on these bases. (See Ibid.)

d. The Superior Court Did Not Err by Limiting the Scope of 

Wallace’s Testimony 

As a final matter, the Zone Defendants argue that the superior court 

improperly limited the testimony of Wallace, their damages expert, by 

precluding him from testifying as to damages suffered as a result of the 

adverse verdict and subsequent settlement in the Patent Litigation. They 
36

assert the superior court’s error in this regard arose from the same error as 

the court’s nonsuit ruling. To the contrary, it is the Zone Defendants’

argument that is based in the same erroneous assumption. 

It is within the superior court’s role as a gatekeeper to exclude expert 

opinions based on assumptions that are not supported by the evidence. (See 

Sargon Enterprises, Inc. v. University of Southern California (2012) 55 

Cal.4th 747, 771; Evid. Code, § 801.) Here, as discussed ante, the Zone 

Defendants failed to present sufficient evidence to establish that they would 

have prevailed in the Patent Litigation absent Stahl’s negligence in failing to 

adequately identify and designate Soika, Heines, and DeFazio as experts. As 

a result, the superior appropriately excluded Wallace from offering his 

opinions on damages based on the unsupported assumption that the Zone 

Defendants would have prevailed in the Patent Litigation absent Stahl’s 

errors. 

Moreover, for largely the same reason, the Zone Defendants have not 

shown any prejudice as a result of the excluded testimony. (See Serri v. 

Santa Clara University (2014) 226 Cal.App.4th 830, 857 [“ ‘an erroneous 

evidentiary ruling requires reversal only if “there is a reasonable probability 

that a result more favorable to the appealing party would have been reached 

in the absence of the error” ‘ “].) The excluded testimony would not have 

established the missing causal link between Stahl’s errors and the outcome of 
37

the Patent Litigation and, thus, would not have had any impact on the 

nonsuit ruling. 

For the foregoing reasons, we conclude that the superior court did not 

err by granting Stahl’s motion for nonsuit with respect to the Zone 

Defendants’ professional malpractice cause of action.

B. The Damages Awarded to Apex and Zone for Stahl’s Breach of 

Fiduciary Duty Were Appropriate but the Damages Awarded to 

McGlothlin Must be Vacated as a Matter of Law 

Turning now to Stahl’s appeal, Stahl argues the damages awarded to 

Apex, Zone, and McGlothlin must be vacated as a matter of law based on the 

damages claimed in the cross-complaint, the Superior Court’s nonsuit ruling, 

and the related findings of the jury.

1. Forfeiture

As Stahl acknowledges, the failure to move for a new trial ordinarily 

precludes a party from complaining on appeal that the damages awarded 

were excessive. (See Jamison v. Jamison (2008) 164 Cal.App.4th 714, 719; 

Glendale Fed. Sav. & Loan Assn. v. Marina View Heights Dev. Co. (1977) 66 

Cal.App.3d 101, 122 (Glendale).) However, as Stahl asserts, his arguments 

address legal errors in the judgment, which may be raised on appeal without 

the filing of a motion for new trial. His arguments are not based on the

specific amount of damages awarded and do not require weighing the 

evidence or resolution of conflicts in the evidence. (See Glendale, at p. 122.) 
38

They are based, instead, on the appropriate measure of damages, which is a 

matter of law. (Ibid. [“The failure to move for a new trial, however, does not 

preclude a party from urging legal errors in the trial of the damage issue 

such as . . . failure to apply the proper legal measure of damages.”].) 

2. Relevant Legal Principles

A breach of fiduciary duty cause of action is a type of tort that is 

distinct from professional malpractice. (Stanley, supra, 35 Cal.App.4th at p.

1086.) “The elements of a cause of action for breach of fiduciary duty are: (1) 

existence of a fiduciary duty; (2) breach of the fiduciary duty; and (3) damage 

proximately caused by the breach. [Citation].” (Ibid.)

As a type of tort, a breach of fiduciary claim is governed by Civil Code 

section 3333, which states: “For the breach of an obligation not arising from 

contract, the measure of damages, except where otherwise expressly provided 

by this Code, is the amount which will compensate for all the detriment 

proximately caused thereby, whether it could have been anticipated or not.”

An attorney has a duty “to charge only fair, reasonable, and 

conscionable fees,” and, thus, a client may state a claim for breach of 

fiduciary duty by alleging the attorney billed at an inflated rate or billed for 

work not complete. (Bird, Marella, Boxer & Wolpart v. Sup. Ct. (2003) 106 

Cal.App.4th 419, 431; Charney v. Colbert (2006) 145 Cal.App.4h 170, 182.) Of 

particular relevance here, the court in Herrington found the plaintiff did not 
39

produce any evidence showing he would have obtained a more favorable 

judgment or settlement but for the attorney’s misconduct but allowed a 

breach of fiduciary duty claim to proceed based on the potential for recovery 

of the fees paid to the attorney. (Herrington, supra, 107 Cal.App.4th at pp. 

1058-1059.) The court stated, “[i]f he [the plaintiff] can prove he did not 

receive value for his payment, he may recover damages ‘to the extent’ the fees 

exceed the value of the services received.” (Id. at p. 1060.)

3. Standard of Review

Determination of whether a party is entitled to a particular measure of 

damages is a question of law subject to de novo review. (Toscano v. Greene 

Music (2004) 124 Cal.App.4th 685, 691; Glendale, supra, 66 Cal.App.3d at 

p. 123.) We also review assertions that special verdict findings are 

inconsistent de novo. (Bermudez v. Ciolek (2015) 237 Cal.App.4th 1311, 

1316.)

4. Analysis 

a. The Jury Properly Awarded Damages to Apex and Zone 

Based on the Legal Fees They Paid to Stahl

We turn first to the damages awarded to the companies, Apex and 

Zone. Stahl asserts the jury’s findings on the special verdict form indicate 

the jury awarded damages to Apex and Zone based on the outcome of the 
40

Patent Litigation and the damages must therefore be vacated based on the 

nonsuit ruling. 

In their cross-complaint, the Zone Defendants alleged that Stahl failed

to adequately prepare the case for trial, abandoned them on the eve of trial, 

placed his own financial interests above those of his clients, and submitted

invoices that “were excessive, unreasonable and not consistent with actual 

time devoted to the matter.”8 However, as explained ante in section II.A., the 

superior court correctly determined that the Zone Defendants did not meet 

their burden to present sufficient evidence from which the jury could have 

concluded that the outcome of the Patent Litigation would have been more 

favorable to them absent Stahl’s errors, and therefore granted the motion for 

nonsuit with respect to the professional malpractice cause of action. 

Given the court’s ruling on the nonsuit, the only damages available to 

the Zone Defendants for breach of fiduciary duty were those based on the 

overpayment of legal fees to Stahl. (See Slovensky, supra, 142 Cal.App.4th 

1533 [“[t]o the extent plaintiff’s fiduciary breach claim alleges the same 

damages as her malpractice claim, it fails for the same reason.”].) Indeed, the 

8 The Zone Defendants moved to amend their pleadings according to 

proof at trial and the court granted the motion in part, allowing a narrow 

amendment to include an allegation that Stahl breached his fiduciary duty 

“by making false and/or misleading statements to his clients regarding events 

in and the status of the case.” However, it does not appear that a Second 

Amended Cross-Complaint was filed. 
41

parties agreed to instruct the jury as follows: “The following are the specific 

items of damages claimed by Apex Medical Technologies, Inc., Zone Medical, 

LLC, and Mark McGlothlin: Legal fees paid to Norbert Stahl related to 

the I-Flow versus Apex litigation.” (Emphasis added.) 

Stahl’s assertion that the jury awarded damages based on the outcome 

of the Patent Litigation is contrary to the court’s ruling on the motion for 

nonsuit and the instruction given to the jury. In the absence of evidence 

indicating otherwise, we must presume the jury followed the court’s 

instruction on damages. (Cassim v. Allstate Ins. Co. (2004) 33 Cal.4th 780, 

803 (Cassim); City of Ripon v. Sweetin (2002) 100 Cal.App.4th 887, 901

(Ripon).) Moreover, as the superior court noted in a subsequent discussion 

regarding disgorgement, the total amount of damages awarded is equal to the 

total amount of fees Apex and Zone paid to Stahl. Thus, we conclude that the 

jury awarded the Zone Defendants, including Zone and Apex, damages based 

on the legal fees paid to Stahl, consistent with the agreed upon instructions

given to them by the court. 

As he did in the prior appeal in case number D073155, Stahl relies on 

the jury’s response to questions 30 and 34 of the special verdict to assert that 

the jury could not have awarded damages based on the legal fees paid to 
42

Stahl.9 We addressed these same assertions in our prior opinion and 

concluded that Stahl’s interpretation of the jury’s response to these questions 

was incorrect. (See D068929 Slip Op. at pp. *18-25.) Stahl’s argument in 

this appeal is no different and our previous analysis applies equally here. 

(See Sefton v. Sefton (2015) 236 Cal.App.4th 159, 172, fn. 6.) 

Apex and Zone were entitled to damages based on the legal fees that 

they paid to Stahl, and the record indicates that the jury appropriately 

awarded them damages on that basis. (See Herrington, supra, 107 

Cal.App.4th at pp. 1058-1059.) We therefore find no error in the judgment 

with respect to the damages awarded to Apex and Zone. 

b. McGlothlin Was Not Entitled to Damages Based on 

Legal Fees Because He Did Not Personally Pay Any of 

Stahl’s Legal Fees

McGlothlin, on the other hand, cannot recover damages for fees paid to 

Stahl in excess of the value received because he did not personally pay any of 

Stahl’s legal fees. McGlothlin testified that he signed the engagement letter 

9 Question 30 relates to the affirmative defense of set off. In the 

immediately preceding questions, the jury concluded the Zone Defendants 

paid more than the reasonable value of services rendered by Stahl. Question 

30 asked the jurors “What are each Defendants’ damages due to those 

overpayments?” and the jurors responded, “$0” for each defendant. Question 

34 follows the award of damages for the breach of fiduciary duty cause of 

action, set forth in question 33, and asks, “For each Cross-Complainant for 

which you entered an amount greater than zero, are the damages you 

awarded in response to question 33, if any, in addition to the damages you 

found, if any, in response to question 30?” The jury responded, “No.”

with Stahl on behalf of Apex and Zone, and not in his personal capacity. He 

suggested that Stahl represented him personally in the case as well, but 

Stahl confirmed that he billed all of the work, whether it was for Apex, Zone, 

or any of the named officers, on a single invoice, and Marasco and DePaul 

both testified that Apex and Zone paid the invoices out of company funds. 

As a corporation and an LLC, Apex and Zone were themselves distinct 

legal entities. (See Abrahim & Sons Enterprises v. Equilon Enterprises, LLC 

(2002) 292 F.3d 958, 962 [“Corporations and LLCs are distinct legal entities, 

separate from their stockholders or members.”].) Thus, even as an officer 

and/or majority shareholder, McGlothlin was not entitled to recover damages 

in his personal capacity based on legal fees paid by Apex and Zone. (See Tan 

Jay Internat v. Canadian Indemnity Co. (1988) 198 Cal.App.3d 695, 706 (Tan 

Jay) [“One individual does not, under our law, become entitled to a damage 

award for injuries sustained by another, and a corporation is a distinct legal 

entity apart from its shareholders”]; Truestone, Inc. v. Travelers Ins. Co. 

(1976) 55 Cal.App.3d 165, 169 [“The allegation that conduct of the defendants 

reduced the value of the Campbells’ shares by injury to the corporation, 

standing alone, does not establish a personal cause of action in the Campbells 

since the diminution of value is incidental to injury to their corporation”].) 

Since McGlothlin did not personally pay any of Stahl’s legal fees, he cannot 

personally recover damages based on the payment of those fees.

Stahl asserts that jury must have awarded damages to McGlothlin 

based, instead, on the outcome of the Patent Litigation. Specifically, he 

argues the jury’s responses to questions 13 and 18 of the special verdict are 

inconsistent and cannot be reconciled with the verdict if we interpret the 

verdict as awarding fees to McGlothlin based on the overpayment of legal fees 

to Stahl. (See Singh v. Southland Stone, U.S.A, Inc. (2010) 186 Cal.App.4th 

338, 357 [“A special verdict is inconsistent if there is no possibility of 

reconciling its findings with each other.”].) We disagree. 

In response to question 13, the jury found that McGlothlin did not 

“request, by words or conduct, that Stahl Law Firm perform services for [his] 

benefit”. The evidence showed that Stahl did represent McGlothlin in the 

Patent Litigation, though, not necessarily at McGlothlin’s request, but in 

connection with his representation of the companies, Apex and Zone. Thus, 

the jury’s response to question 13 is not inconsistent with the verdict. 

In response to question 18, the jury found that McGlothlin did not have 

any “financial transactions” with Stahl, which is consistent with the evidence 

indicating McGlothlin did not personally pay any of Stahl’s legal fees. 

However, the jury was not instructed that McGlothlin could not recover 

damages based on legal fees paid to Stahl by Apex and Zone. Thus, it is 

possible that the jury awarded damages for legal fees paid to Stahl based on a 

mistaken presumption that McGlothlin could recover personally as a 
45

company officer. Indeed, the jury was instructed that the only specific 

damages claimed by the Zone Defendants with respect to the breach of 

fiduciary duty cause of action were the legal fees paid to Stahl. We presume 

the jury followed this instruction. (See Cassim, supra, 33 Cal.4th at p. 803; 

Ripon, supra, 100 Cal.App.4th at p. 901.) 

The Zone Defendants argue that McGlothlin established damages 

“going well beyond disgorgement.” However, they do not identify any specific 

damages not related to the outcome of the Patent Litigation or the 

overpayment of legal fees to Stahl. As discussed, ante, the superior court 

correctly found that the Zone Defendants did not present adequate evidence 

upon which the jury could conclude that the outcome of the case would have 

been different but for Stahl’s errors. The only remaining basis for damages 

on the fiduciary duty cause of action before the jury was the fees paid to 

Stahl. As we have concluded, though, McGlothlin was not entitled to 

damages based on legal fees that he did not personally pay. Accordingly, we 

agree with Stahl that the damages awarded to McGlothlin in his personal 

capacity must be vacated as a matter of law.

C. Costs 

As a final matter, Stahl asserts the award of costs should also be

vacated but provides no authority for the assertion. As discussed more fully 

in our concurrently filed opinion in D073155, the Zone Defendants were still 
46

the prevailing party as they prevailed on the claims asserted against them by 

Stahl and were therefore entitled to costs. 

DISPOSITION

The judgment is modified by striking the $312,385.20 in damages 

awarded to McGlothlin. In all other respects, the judgment is affirmed. The 

parties are to bear their own costs on appeal.
