Gloria Chaparro (Gloria) and David Chaparro (David) (collectively the Chaparros) 

appeal the summary judgment entered in favor of respondent Dr. Arlene Nepomuceno on 

Gloria’s claim for medical malpractice and David’s bystander claim for emotional 

distress. There are triable issues regarding breach of the duty of care, causation and 

damages because the parties offered competing declarations from medical experts. 

Moreover, Chaparro v. Cimmarusti (Dec. 31, 2013) B244757 [nonpub. opn.] 

(Chaparro I) does not trigger the collateral estoppel doctrine and preclude a finding of 

causation. Finally, there are triable issues regarding David’s bystander claim. We 

reverse. 

FACTS

The Complaint

On September 27, 2011, Gloria sued Dr. Jerry Cimmarusti, a physician’s assistant 

named Renee Parrilla (Parrilla), Doe 10, various other Doe defendants, and Magan 

Medical Clinic, Inc. (Magan) for medical malpractice. David sued them for bystander 

recovery.

The complaint alleged: 

Dr. Cimmarusti, Parrilla and Doe 10 were employed by or under contract with 

Magan. On July 7, 2010, David took Gloria to the Urgent Care Clinic operated by 

Magan because she was coughing up blood and had shortness of breath. She was 

examined by Parrilla. After the examination, Gloria coughed up blood in the parking lot 

and returned to the Urgent Care Clinic and asked for further evaluation. She was told to 

go home and wait for a CT scan that had been scheduled for the following week. 

Gloria’s condition got worse. On July 17, 2010, David took Gloria to an emergency 

room and she was admitted to the hospital. A CT scan revealed the presence of a large 

mass in her chest. The mass was an empyema, a large collection of pus in the space 

between the lung and the inner surface of the chest wall. On July 23, 2010, Gloria 

underwent a thoracentesis to remove the empyema. Magan is vicariously liable for the 

negligence of Doe 10, Dr. Cimmarusti and Parrilla. Those three, and various other Doe 

defendants, breached the standard of care by failing to diagnose and treat Gloria’s illness 
3

on a timely basis. David alleged that he suffered emotional distress when he saw Gloria 

being injured.

The July 3, 2012, Motion for Summary Judgment by Dr. Cimmarusti, Parrilla and 

Magan

Dr. Cimmarusti, Parrilla and Magan submitted a motion for summary judgment 

supported by the declaration of Dr. Abraham Ishaaya. He reviewed the relevant medical 

records and noted, among other things, that Gloria was seen on July 9, 2010, by 

Dr. Nepomuceno. He opined, inter alia, that Dr. Cimmarusti, Parrilla and other 

healthcare providers at Magan “appropriately evaluated [Gloria] and arranged the 

appropriate follow up. Nothing that any of the above noted healthcare providers did or

did not do contributed to the rapid progression of the findings seen on [Gloria’s] chest xray and the development of empyema.”

The July 10, 2012, Doe Amendment

The Chaparros substituted Dr. Nepomuceno’s name into the complaint in place of 

the fictitious name of Doe 10.

The Chaparros’ Opposition to the Motion for Summary Judgment by 

Dr. Cimmarusti, Parrilla and Magan

To defeat summary judgment, the Chaparros’ offered a competing declaration 

from Dr. Paul K. Bronston opining that to a reasonable degree of medical certainty, 

“standards of care were breached in the evaluation of care of [Gloria] at [Magan].” He 

specifically noted that Gloria was taken to Magan on July 9, 2010, and “was seen by a 

physician who found her to be weak and dizzy.” Dr. Bronston then noted: “In spite of 

[Gloria’s] obvious worsening condition, the physician did not check [Gloria’s] oxygen 

saturation level. No chest x-ray was done. The physician simply sent [Gloria] home with 

an appointment to see her primary doctor in another week. As [previously] explained 

. . . , this violated standards of care.” Dr. Bronston did not offer an opinion as to whether 

any healthcare provider caused damages.

The September 24, 2012, Summary Judgment for Dr. Cimmarusti, Parrilla and 

Magan

At oral argument on the motion by Dr. Cimmarusti, Parrilla and Magan, the trial 

court ruled that there was no triable issue as to causation because the Chaparros did not 

have an expert on that issue. Counsel for the Chaparros argued that because they were 

alleging that the failure to treat Gloria’s empyema caused pain and suffering, an expert on 

causation was unnecessary. The trial court granted the motion for summary judgment 

and entered judgment accordingly.

The Chaparros appealed.

Dr. Nepomuceno’s December 24, 2012, Motion for Summary Judgment

Dr. Nepomuceno moved for summary judgment on the grounds that there were no 

triable issues of fact regarding whether she breached the standard of care or caused 

damages. Dr. Ishaaya provided an accompanying expert declaration in which he opined 

that Dr. Nepomuceno met the standard of care on July 9, 2010, and was not responsible 

for causing Gloria to suffer any damages. In the alternative, Dr. Nepomuceno argued that 

the Chaparros’ action against her was barred by collateral estoppel due to the summary 

judgment granted in favor of Dr. Cimmarusti, Parrilla and Magan. Dr. Nepomuceno 

pointed out that in connection with the prior motion, the trial court had ruled as follows: 

“[T]o a reasonable degree of medical probability no act or omission o[n] the part of 

[Dr. Cimmarusti], [Parrilla], or any other healthcare provider at [Magan] caused or 

contributed to or was a substantial factor in causing any injuries or damages to [Gloria].”

With respect to David, Dr. Nepomuceno argued that he could not establish the 

elements of his bystander claim.

The Chaparros’ Opposition to the Motion for Summary Judgment by 

Dr. Nepomuceno

In opposition, the Chaparros offered the declaration of Dr. Angelique S. Campen. 

She declared that Parrilla was not qualified to diagnose Gloria on July 7, 2010, and 

breached the standard of care when she did not consult with or call a physician. 

Dr. Nepomuceno breached the standard of care by failing to diagnose pneumonia and 
5

start Gloria on antibiotics when she presented on July 9, 2010, to Magan with hemoptysis 

(coughing up blood). Her breaches “substantially contributed to an overall 10-day delay 

in the diagnosis and treatment of pneumonia and this delay proximately caused [Gloria] 

to develop an empyema which could have been avoided[.]” In addition, 

Dr. Nepomuceno’s breaches “were a substantial factor in causing [Gloria] pain and 

suffering associated with having to undergo thoracentesis and open chest surgery to 

remove the empyema[.]” Dr. Campen based her opinion, inter alia, on the following. 

Dr. Nepomuceno should have known that a patient who presents within days with the 

same or a worsening condition is a hallmark of disease escalation, and she should have 

reviewed the findings from the prior visit, performed a complete physical and gotten a 

basic chest x-ray. Three days later, Dr. Cimmarusti ordered a chest x-ray that revealed 

the presence of multiple infiltrates indicative of pneumonia. He gave Gloria a 

prescription for doxycycline, “which is not appropriate broad-spectrum coverage for 

pneumonia.” Empyema “can develop from untreated pneumonia. . . .” Gloria’s 

“empyema was caused by untreated bacterial pneumonia which was her only risk factor 

for its development.” Dr. Campen concluded: “Within a reasonable degree of medical 

probability, the breaches in the standards of care explained above including those by 

Dr. Nepomuceno, caused and contributed to at least 10 days of delay in proper diagnosis 

and treatment of pneumonia which further proximately caused an empyema to develop.”

As to David, the Chaparros argued that he established a triable issue regarding his 

bystander claim because the evidence showed that he was present at each encounter 

Gloria had at Magan. On July 9, 2010, Gloria coughed up blood into his hand after she 

was seen by Dr. Nepomuceno; Dr. Nepomuceno turned Gloria away when she tried to be 

seen a second time; and Dr. Nepomuceno refused David’s request that Gloria be given a 

second opinion and sent to the hospital.

The Chaparros argued that the collateral estoppel argument should be rejected 

because the doctrine curtails subsequent litigation in a second action and the claim 

against Dr. Nepomuceno was not asserted in a second action; Dr. Nepomuceno did not 
6

refer to the relevant facts in her separate statement; and she did not allege collateral 

estoppel as an affirmative defense in her answer.

Dr. Nepomuceno’s Reply

In her reply, Dr. Nepomuceno argued that the Chaparros failed to establish a 

triable issue as to causation. She did not analyze the collateral estoppel issue, nor did she 

analyze David’s bystander claim.

The March 14, 2013, Summary Judgment for Dr. Nepomuceno

The trial court granted Dr. Nepomuceno’s motion on the grounds that there was no 

triable issue as to causation. Specifically, the trial court concluded that Dr. Campen

failed to establish that Dr. Nepomuceno’s negligence “was in and of itself sufficient to 

bring about [Gloria’s] injuries.” David’s bystander claim was rejected because it was 

derivative of Gloria’s claim.

The collateral estoppel argument was rejected. In its tentative ruling, which was 

adopted as part of the order granting summary judgment, the trial court cited case law 

establishing that collateral estoppel applies only to a later filed action. The trial court 

then stated that “based on the above authorities and [Dr. Nepomuceno’s] failure to assert 

the defense[], this court finds that . . . collateral estoppel does not preclude the instant 

action against Dr. Nepomuceno[.]”

Judgment was entered for Dr. Nepomuceno.

This timely appeal followed.

Our Opinion in Chaparro I

In connection with their appeal of the summary judgment entered in favor of 

Dr. Cimmarusti, Parrilla and Magan, the Chaparros argued that an expert declaration was 

not necessary to establish causation. We disagreed. On December 31, 2013, we issued 

an opinion affirming summary judgment.

DISCUSSION

The Chaparros contend that summary judgment was improper because there are

triable issues as to causation. Dr. Nepomuceno argues that collateral estoppel applies due 

to the summary judgment entered in favor of Dr. Cimmarusti, Parrilla and Magan, and 

that David’s bystander claim lacks merit. Our review is de novo. (Merrill v. Navegar, 

Inc. (2001) 26 Cal.4th 465, 476.)

I. Causation.

In the law, a cause of injury is defined as anything that is a substantial factor in 

bringing about that injury. (Espinosa v. Little Co. of Mary Hospital (1995) 31 

Cal.App.4th 1304, 1314.) “‘The substantial factor standard is a relatively broad one, 

requiring only that the contribution of the individual cause be more than negligible or 

theoretical.’ [Citation.] Thus, ‘a force which plays only an “infinitesimal” or 

“theoretical” part in bringing about injury, damage, or loss is not a substantial factor’ 

[citation], but a very minor force that does cause harm is a substantial factor [citation]. 

This rule honors the principle of comparative fault. [Citation.]” (Bockrath v. Aldrich 

Chemical Co. (1999) 21 Cal.4th 71, 79.)

A plaintiff who is litigating a medical malpractice action must provide competent 

expert testimony establishing a reasonable medical probability that the defendant caused 

the plaintiff’s injury. (Jennings v. Palomar Pomerado Health Systems, Inc. (2003) 114 

Cal.App.4th 1108, 1118 (Jennings).) That said, an expert “does not possess a carte 

blanche to express any opinion within the area of expertise. [Citation.] For example, an 

expert’s opinion based on assumptions of fact without evidentiary support [citation], or 

on speculative or conjectural factors [citation], has no evidentiary value [citation] and 

may be excluded from evidence. [Citations.] Similarly, when an expert’s opinion is 

purely conclusory because unaccompanied by a reasoned explanation connecting the 

factual predicates to the ultimate conclusion, that opinion has no evidentiary value 

because an ‘expert opinion is worth no more than the reasons upon which it rests.’

[Citation.]” (Id. at p. 1117; Kelley v. Trunk (1998) 66 Cal.App.4th 519, 525 [summary 

judgment standard is “not satisfied by laconic expert declarations which provide only an 
8

ultimate opinion, unsupported by reasoned explanation”]; McGonnell v. Kaiser Gypsum 

Co. (2002) 98 Cal.App.4th 1098, 1106 [“Plaintiffs cannot manufacture a triable issue of 

fact through use of an expert opinion with self-serving conclusions devoid of any basis, 

explanation, or reasoning”].)

Read fairly, Dr. Campen’s declaration opined that Gloria was ill on July 7, 2010, 

and her illness escalated within several days; on July 9, 2010, Dr. Nepomuceno should 

have diagnosed Gloria with bacterial pneumonia and given her proper antibiotics; 

doxycycline, prescribed by Dr. Cimmarusti on July 12, 2010, was not an appropriate 

treatment; Gloria’s empyema was caused by a 10-day delay in the proper treatment of her 

bacterial pneumonia; if Gloria had received proper treatment earlier, her epyema would 

have been avoided; and Dr. Nepomuceno’s breaches of the standard of care caused and 

contributed to Gloria’s empyema to a reasonable medical certainty. 

In our view, Dr. Campen’s declaration passes muster because she provided a 

factual basis for her opinion, which was that the empyema developed, in part, because 

Dr. Nepomuceno did not prescribe Gloria with proper antibiotics on July 9, 2010. 

Despite Dr. Nepomuceno’s contention, Dr. Campen’s declaration is not akin to the 

evidence found deficient in Jennings. The doctor in Jennings “testified that, if a 

constellation of events had coalesced, the retractor could have provided a nidus for 

bacteria to grow inside Jennings’s peritoneal cavity during the window of time ending 

when the retractor became encased by the omentum.” (Jennings, supra, 114 Cal.App.4th 

at p. 1119.) Next, the doctor testified “that bacteria growing around the retractor were a 

cause-in-fact of the infection.” (Ibid.) The court concluded that the testimony “was not 

helpful to the jury absent additional evidence that it was more likely than not that bacteria 

growing around the retractor migrated to and were a cause-in-fact of the infection in the 

subcutaneous tissue,” and that the “opinion was too conclusory to satisfy the 

requirements for admissibility. [Citation.]” (Id. at pp. 1119–1120.) In particular, the 

doctor never explained why it was “more likely than not that the bacteria, after 

multiplying without any clinical symptoms that ordinarily accompany peritonitis, 

migrated from the nidus within the peritoneal cavity through the sutured peritoneal wall, 
9

the transversalis fascia, the muscle group and the rectus fascia, finally settling into the 

subcutaneous tissue, while leaving the peritoneal wall intact and leaving behind no trail 

of inflamed or infected tissue evidencing this migration. Instead, [the doctor] substituted 

a conclusion in place of an explanation, opining ‘[i]t just sort of makes sense. We have 

that ribbon retractor and [it’s] contaminated, he’s infected.’” (Id. at p. 1120.) Here, the 

concepts involved are less complicated because the issue is not how and whether 

Dr. Nepomuceno caused an infection, but whether she properly treated an infection. If an 

ailment is not properly treated, it is logical to conclude that the lack of proper treatment 

was the very thing that caused the ailment to escalate.

Nor is this case similar to Bushling v. Fremont Medical Center (2004) 117 

Cal.App.4th 493 (Bushling). In that case, two doctors “were of the opinion that plaintiff's 

injury was caused by defendants’ negligence in that ‘more probably than not,’ plaintiff 

had been dropped, his arm had been improperly positioned during surgery, or his arm had 

been stretched.” (Id. at p. 510.) The court rejected the opinions, stating: “The difficulty 

that plaintiff encounters in his attempt to avoid summary judgment by relying on the 

[doctors’] opinions is that there is no evidence that plaintiff was dropped, that he was 

improperly positioned, or that his arm was stretched during the procedure or recovery. 

The doctors assume the cause from the fact of the injury. [Their] opinions are nothing 

more than a statement that the injury could have been caused by defendants’ negligence 

in one of the ways they specify. But, ‘an expert’s opinion that something could be true if 

certain assumed facts are true, without any foundation for concluding those assumed facts 

exist’ [citation], has no evidentiary value. [Citation.]” (Ibid.) Contrasting, we note that 

Dr. Campen did not assume that one of several unproven causes of Gloria’s injury might 

have occurred. Rather, Dr. Campen opined that the empyema was caused by 

Dr. Nepomuceno’s failure to treat Gloria’s bacterial pneumonia with proper antibiotics on 

July 9, 2010. That opinion was based on the undisputed facts that Gloria exhibited 

symptoms of illness and Dr. Nepomuceno did not provide treatment.

Dr. Nepomuceno argues that there was no evidence that her negligence, by itself, 

caused injury. We cannot concur. Dr. Campen opined that if Dr. Nepomuceno had met 
10

the standard of care and prescribed the proper treatment on July 9, 2010, then Gloria 

would not have had an empyema. This meets the substantial factor test. It does not 

matter that Parrilla and Dr. Cimmarusti might also be at fault. Next, Dr. Nepomuceno 

contends that summary judgment was proper because she did not cause a 10-day delay in 

treatment which, according to Dr. Campen, caused the empyema. At most, argues 

Dr. Nepomuceno, she caused a three-day delay because Dr. Cimmarusti identified 

Gloria’s pneumonia on July 12, 2010, and prescribed antibiotics. Once again, we cannot 

concur. According to Dr. Campen, Dr. Cimmarusti prescribed the wrong antibiotics and 

Gloria did not obtain proper treatment until after she went to the hospital. Thus, per 

Dr. Campen, Dr. Nepomuceno contributed to an over-all 10-day delay in Gloria receiving 

proper treatment.

II. Collateral Estoppel.

Dr. Nepomuceno argues that we should affirm the summary judgment granted in 

her favor based on the collateral estoppel effect of the summary judgment granted in 

favor of Dr. Cimmarusti, Parrilla and Magan. We disagree.

Collateral estoppel applies if the party against whom the doctrine is asserted was a 

party or in privity with a party in a previous proceeding (Rodgers v. Sargent Controls & 

Aerospace (2006) 136 Cal.App.4th 82, 90 (Rodgers)), and if the advocating party 

establishes the following: “First, the issue sought to be precluded from relitigation must 

be identical to that decided in a former proceeding. Second, this issue must have been 

actually litigated in the former proceeding. Third, it must have been necessarily decided 

in the former proceeding. Fourth, the decision in the former proceeding must be final and 

on the merits. Finally, the party against whom preclusion is sought must be the same as, 

or in privity with, the party to the former proceeding.’ [Citation.] Even if these threshold 

requirements are satisfied, the doctrine will not be applied if such application would not 

serve its underlying fundamental principles. [Citation.]” (Gikas v. Zolin (1993) 6 Cal.4th 

841, 848–849.)

At the time the trial court ruled on Dr. Nepomuceno’s motion, she could not have 

established the elements of collateral estoppel because the motion was brought in the 
11

same action as the summary judgment for Dr. Cimmarusti, Parrilla and Magan. Also, the 

summary judgment for Dr. Cimmarusti, Parrilla and Magan was not final because the 

matter was on appeal. (Lumpkin v. Jordan (1996) 49 Cal.App.4th 1223, 1231, fn. 5 

[“Under California law, a judgment is not final for purposes of collateral estoppel while 

open to direct attack, e.g., by appeal”]; Long Beach Unified Sch. Dist. v. State of 

California (1990) 225 Cal.App.3d 155, 169 [“A decision will not be given collateral 

estoppel effect if [an] appeal has been taken”].) Finally, preventing the Chaparros from 

litigating the adequacy of Dr. Campen’s declaration will not serve the underlying 

fundamental principles of collateral estoppel, i.e., preserving the integrity of the judicial 

system and protecting opposing parties from vexatious litigation. (Lucido v. Superior 

Court (1990) 51 Cal.3d 335, 339.) Because the motion for summary judgment by 

Dr. Cimmarusti, Parrilla and Magan involved the adequacy of Dr. Bronston’s declaration 

and the motion by Dr. Nepomuceno involved the adequacy of Dr. Campen’s declaration, 

the latter motion did not threaten the integrity of the judicial system by asking the trial 

court to decide the same issue twice. And because the Chaparros did not seek to litigate 

the same issue twice, they were not being vexatious.

III. David’s Bystander Claim.

Insofar as the trial court granted summary judgment against David solely because 

Gloria’s claim lacked merit and his bystander claim for negligent infliction of emotional 

distress (NIED) was derivative, that was error. We could, of course, affirm summary 

judgment against David if it was supported by a legal theory not reached by the trial 

court, but we would have to exercise our discretion to reach the issue. (Code Civ. Proc., 

§ 437c, subd. (m)(2).) We choose not to.

In reaching this conclusion, we note the following. Dr. Nepomuceno urges us to 

conclude that David’s bystander claim is barred because he could not have been 

contemporaneously aware of an injury-producing event during Gloria’s visit to Magan on 

July 9, 2010. The law provides “‘that a plaintiff may recover damages for emotional 

distress caused by observing the negligently inflicted injury of a third person if, but only

if, said plaintiff: (1) is closely related to the injury victim; (2) is present at the scene of 
12

the injury-producing event at the time it occurs and is then aware that it is causing injury 

to the victim; and (3) as a result suffers serious emotional distress—a reaction beyond 

that which would be anticipated in a disinterested witness and which is not an abnormal

response to the circumstances.’ [Citation.]” (Bird v. Saenz (2002) 28 Cal.4th 910, 915.) 

“Except in the most obvious cases, a misdiagnosis is beyond the awareness of lay 

bystanders.” (Id. at p. 917.) In general, “courts have not found a layperson’s observation 

of medical procedures to satisfy the requirement of contemporary awareness of the 

injury-producing event.” (Id. pp. 917–918.) But “[t]his is not to say that a layperson can 

never perceive medical negligence, or that one who does perceive it cannot assert a valid 

claim for NIED. To suggest an extreme example, a layperson who watched as a 

relative’s sound limb was amputated by mistake might well have a valid claim for NIED 

against the surgeon. Such an accident, and its injury-causing effects, would not lie 

beyond the plaintiff’s understanding awareness. But the same cannot be assumed of 

medical malpractice generally.” (Id. at p. 918.)

The problem for Dr. Nepomuceno, at least for purposes of this appeal, is that she 

did not adequately develop her argument. She provided only a single record citation to 

two lines in David’s deposition in which he denied having medical training. And she did 

not analyze whether damages for an NIED claim could be supported by the evidence of 

what David actually witnessed.
