TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN

NO. 03-19-00186-CV

D. L. E. B., Appellant

v.

Texas Department of Family and Protective Services, Appellee

FROM THE 421ST DISTRICT COURT OF CALDWELL COUNTY

NO. 18-FL-250, CHRIS SCHNEIDER, JUDGE PRESIDING

M E M O R A N D U M O P I N I O N

In this appeal from the trial court’s order terminating D.L.E.B.’s parental rights to 

her child, L.J.B., the only issue is a challenge to the trial court’s denial of D.L.E.B.’s request to 

conduct a Rule 705(b) examination of an expert witness. See Tex. R. Evid. 705(b) (before expert 

states opinion, trial court may permit party to examine expert outside jury’s hearing about facts 

or data underlying expert’s opinion). We will affirm.

BACKGROUND

In June 2018, the Department was informed that D.L.E.B. and an unrelated 

household member had tested positive for cocaine.1 The Department’s investigator, Christine 

 

1

 The Department had ongoing investigations into the family related to two other 

children. D.L.E.B. had extensive involvement with the Department dating back to 2002 related 

to allegations of abuse and neglectful supervision of four of L.J.B.’s siblings. The court had 
2

Timmons, checked the drug testing website and verified that the reported test results had been 

posted. Timmons went to D.L.E.B.’s home to check on L.J.B.’s welfare. L.J.B. was 

approximately one year old and living with D.L.E.B. and her husband and L.J.B.’s presumed 

father, M.B. When Timmons arrived, D.L.E.B. was not at home, but Timmons spoke with M.B., 

who reported that he was not sure whether D.L.E.B. was using illegal substances. When 

Timmons informed M.B. of the drug test results, M.B. stated that he was concerned because 

D.L.E.B. was L.J.B.’s primary caretaker. M.B., who was 83 years old, told Timmons that he 

could not care for L.J.B. by himself and that he believed it would be best if Timmons took L.J.B. 

into custody. Timmons then contacted D.L.E.B. by telephone. D.L.E.B. stated that she would 

be home shortly. When D.L.E.B. arrived at the home, Timmons told D.L.E.B. about the positive 

drug test. D.L.E.B. stated that M.B. had given her money about ten days earlier and that she had 

used that money to buy cocaine. M.B. denied that he knew D.L.E.B. was going to buy drugs 

with the money, but D.L.E.B. stated that M.B. knew what she intended to do with it. After 

D.L.E.B. acknowledged that she had used cocaine five times that month while she was caring for 

L.J.B., Timmons asked if D.L.E.B. would take an “instant drug test.” D.L.E.B. agreed and stated 

that the drug test would be positive for cocaine, which it was. Timmons asked D.L.E.B. if there 

was anyone else who could supervise her and L.J.B. D.L.E.B. could not provide the name of 

anyone who could help care for L.J.B., and M.B. reaffirmed that he could not care for 

her himself.

Timmons then stepped outside the house to call Department supervisor Kelli 

Johnson. While Timmons was outside, neighbors approached Timmons and told her they were 

 

terminated D.L.E.B.’s parental rights to two of those siblings, and the remaining two had been 

placed in foster care.
3

concerned for the child. The neighbors stated that D.L.E.B. had been seen with a known drug 

dealer in the neighborhood and that they were concerned she was using drugs. Johnson told 

Timmons that the on call program director had given an approval for an exigent removal of 

L.J.B. from the home without D.L.E.B.’s signature based on D.L.E.B.’s drug use and M.B.’s 

statements that he would not be able to recognize whether D.L.E.B. was using drugs and that he 

was unable to care for L.J.B. Timmons went back inside the house and informed D.L.E.B. of the 

Department’s intent to take L.J.B. into custody. D.L.E.B. told Timmons that “she knew this was 

going to happen” and that she had only “slipped” and was not really a drug user. Timmons 

explained the Department’s concern for L.J.B. because D.L.E.B. was the child’s primary 

caregiver and was under the influence of cocaine. D.L.E.B. told Timmons that she understood 

and would work any services necessary to regain custody of her daughter.

On June 28, 2018, the district court signed an order appointing the Department 

L.J.B.’s temporary managing conservator and D.L.E.B. and M.B. as L.J.B.’s temporary 

possessory conservators with court-ordered periods of access and possession.2 L.J.B. was placed 

with foster parents. In July 2018, the Department moved for a finding of aggravated

circumstances. See Tex. Fam. Code § 262.2015 (providing for waiver of requirements of service 

plan and reasonable efforts to return child to parent and for accelerated trial schedule if court 

finds that parent has subjected child to aggravated circumstances). The Department stated that,

since taking L.J.B. into custody, two separate hair follicle tests performed on L.J.B.’s hair tested 

positive for cocaine at extremely high levels. At the hearing, L.J.B.’s attorney ad litem elicited 

 

2

 The court later dismissed M.B. from the case after finding, based on genetic test results,

that M.B. was not L.J.B.’s biological father.
4

testimony from an expert witness, Bruce Jefferies, regarding the drug testing of L.J.B.’s 

hair follicles.

Jefferies testified that he has, over the past 20 years, interviewed people who have 

undergone drug testing at Quest Diagnostics. In these interviews, Jefferies questions the 

individuals about their drug use. Jefferies testified that by correlating the drug tests with the 

information gleaned from the interviews he has, over the years, developed the ability to 

determine from the level of drugs detected in the test whether the person has engaged in “low use 

or high use or recreational use, exposure, non-exposure.” Jefferies testified that he has 

developed a unique expertise in determining, from the number of picograms of drugs detected in 

the particular sample, the degree to which the person has used the particular drug detected. 

Jefferies reviewed the results of the lab testing done on L.J.B.’s hair and requested that a second 

test be run at Quest Diagnostics because that lab was FDA approved for drug tests on hair 

follicles and he believed its testing would provide more accurate information regarding the 

number of picograms of cocaine present in L.J.B.’s hair. Jefferies testified in detail about the 

process Quest Diagnostics uses for testing hair follicles. The test of L.J.B.’s hair was positive for 

cocaine and two cocaine metabolites, norcocaine and benzoylecgonine. Jefferies stated that the

presence of the metabolites indicated that L.J.B. had ingested cocaine. Jefferies testified that the 

amount of cocaine detected, more than 20,000 picograms, indicated that, in his opinion, L.J.B. 

had ingested cocaine “on a daily basis” over the 90 days before the hair follicle was tested. 

Jefferies opined that L.J.B. might have ingested cocaine either through breastfeeding or by eating 

cocaine left by someone in an accessible place. Jefferies stated that 20,000 picograms is a “very 

extreme high level of cocaine” in a child’s system and indicates chronic ingestion of cocaine. 

D.L.E.B.’s attorney cross-examined the witness but did not object to any aspect of Jefferies’s
5

testimony. After the hearing, the court granted the motion for a finding of aggravated 

circumstances and ordered that visits between D.L.E.B. and L.J.B. cease until further court order.

The case was set for a jury trial in March 2019. At the pretrial conference, the 

parties agreed to pre-admit several exhibits, including Jefferies’s curriculum vitae and the 

reporter’s record of his testimony from the hearing on the motion for a finding of aggravated 

circumstances. After the jury was empaneled, D.L.E.B.’s counsel stated that he had something 

he “wanted to put on the record.” He then stated:

I distributed to all counsel and I’ll give it to the Court a case. It’s the leading 

case. It’s sort of the newest version of the Daubert case in Texas from the Texas 

Supreme Court. It’s from 1996. It’s still widely cited. And this case concerns 

the qualifications of an expert.[3] We’ve got a drug expert coming in from 

Houston.[4] And I’m not challenging him at this point.

What I want to do is I want to have a Rule 705B hearing outside the presence of 

the jury to discuss his qualifications to reach an ultimate issue. And I think I’m 

entitled to do that. I don’t see anything in the pretrial order saying I can’t do that. 

And it makes sense to do that, because otherwise I’d end up asking him a bunch 

of questions on the witness stand and anyway in front of the jury. And I just 

as soon follow the rule and do it outside the presence of the jury and run a 

cleaner trial.

After hearing arguments from counsel, the trial court stated that it would consider the request and 

that if it did agree to permit a Rule 705(b) examination of Jefferies, it would take place at the 

lunch break on the first day of trial. On the morning of the first day of trial, the court informed 

the parties that it was not granting the request to conduct a Rule 705(b) examination. The trial 

 

3

 The case referred to is E.I. du Pont de Nemours & Co. v. Robinson, 923 S.W.2d 549 

(Tex. 1995), a case in which the Texas Supreme Court determined the proper standard for 

admission of scientific expert testimony under Rule 702 of the Texas Rules of Evidence.

4

 The expert referred to is Bruce Jefferies.
6

court observed that Jefferies had already testified without objection at a previous hearing and that 

both his curriculum vitae and a transcript of his testimony had been admitted into evidence

without objection.

Jefferies was called as a witness at trial and provided substantially the same 

testimony as he had previously given at the hearing on the motion for a finding of aggravated 

circumstances. Counsel for D.L.E.B. did not object to the testimony regarding the levels of 

cocaine found in L.J.B.’s hair follicles or to the testimony that the levels constituted a very high 

concentration of cocaine. D.L.E.B.’s counsel cross-examined the witness, focusing primarily on 

how the rate of growth of a person’s hair might affect the levels of cocaine that would be 

detected in a hair follicle drug test. He also questioned Jefferies regarding his methodology and 

whether it had been peer reviewed. D.L.E.B.’s counsel did not, however, either object to or 

move to exclude Jefferies’s testimony on any ground.

After a two day trial, at which a number of witnesses testified, the jury returned 

its verdict finding that grounds existed to terminate D.L.E.B.’s parental rights to L.J.B. and that 

termination was in L.J.B.’s best interest. The jury further found that L.J.B.’s foster parents 

should be named her managing and possessory conservators. Thereafter, the trial court signed an 

order terminating D.L.E.B.’s parental rights to L.J.B. and appointing L.J.B.’s foster parents as 

her joint managing conservators. D.L.E.B. then perfected this appeal. In one issue, D.L.E.B. 

asserts that the trial court abused its discretion when it denied the request to conduct a Rule 

705(b) examination of Jefferies.
7

DISCUSSION

Rule 705(b) provides that, before an expert in a civil trial states an opinion or 

discloses the underlying facts or data supporting that opinion, an adverse party may be permitted 

to examine the expert about the underlying facts or data outside the jury’s hearing. Tex. R. Evid. 

705(b). In support of her argument that the trial court abused its discretion by not permitting her 

to conduct such an examination, D.L.E.B. relies on the Texas Supreme Court’s holding in E.I. du 

Pont de Nemours & Co. v. Robinson that scientific evidence that is “not grounded ‘in the 

methods and procedures of science’ is no more than ‘subjective belief or unsupported 

speculation.’” 923 S.W.2d 549, 557 (Tex. 1995) (citing Daubert v. Merrell Dow Pharm., Inc., 

509 U.S. 579, 590 (1993)). D.L.E.B. correctly asserts that Robinson lays out the factors a trial 

court may consider in making a threshold determination of the admissibility of expert testimony 

under Rule 702 of the Texas Rules of Evidence. See id. at 557. These include the extent to 

which the theory has or can be tested, the extent to which the technique relies on the subjective 

interpretation of the expert, whether the theory has been subjected to peer review or publication, 

and whether the underlying theory or technique has been generally accepted as valid by the 

relevant scientific community. Id. In her brief on appeal, D.L.E.B. argues that Jefferies’s

testimony at trial revealed that his technique was not peer reviewed and did not meet the standard 

for admissibility laid out by the supreme court in Robinson. D.L.E.B. asserts that the trial court’s 

refusal to permit counsel to conduct a Rule 705(b) examination of the expert prevented her from 

“bring[ing] the deficiencies [in the expert’s testimony] to the court’s attention before the jury 

heard it.”

Rule 705 creates a procedural mechanism to voir dire an expert outside the 

presence of the jury. The purpose of this examination is twofold: (1) it provides the defendant 
8

the opportunity to determine the foundation of the expert’s opinion without the fear of eliciting 

inadmissible evidence in the jury’s presence, and (2) it may supply the defendant with “sufficient 

ammunition to make a timely objection to the expert’s testimony on the ground that it lacks a 

sufficient basis for admissibility.” Goss v. State, 826 S.W.2d 162, 168 (Tex. Crim. App. 1992); 

see Tex. R. Evid. 705(c).

The use of the word “may” in Rule 705(b) makes a voir dire examination of an 

expert outside the presence of the jury discretionary with the court in civil cases. See Tex. R. 

Evid. 705(b).5 “The test for abuse of discretion is whether the trial court acted without reference 

to any guiding rules or principles.” Broders v. Heise, 924 S.W.2d 148, 151 (Tex. 1996). In the 

present case, D.L.E.B.’s counsel stated that he desired to conduct a 705(b) examination to 

“discuss [Jefferies’s] qualifications to reach an ultimate issue.” That, however, is not the 

purpose of a Rule 705(b) hearing which, instead, is designed to permit a party “to examine the 

expert about the underlying facts or data.” See Tex. R. Evid. 705(b); In re Estate of Trawick, 

170 S.W.3d 871, 875 (Tex. App.—Texarkana 2005, no pet.) (“The contestant’s request to voir 

dire the witness for the purpose of ‘going into’ his qualifications did not invoke the rules 

pertaining to inquiry into ‘the underlying facts or data’ on which the expert’s opinions are 

based.”). Moreover, the trial court’s denial of the request for a voir dire examination outside the 

presence of the jury in no way hindered counsel’s ability to challenge Jefferies’s qualifications 

during the trial through cross-examination or otherwise. See Gammill v. Jack Williams 

Chevrolet, Inc., 972 S.W.2d 713, 728 (Tex. 1998) (emphasizing that trial court’s gatekeeping 

 

5

 In a criminal case by contrast, the party against whom the opinion is being offered has 

a right to examine the expert outside the presence of the jury as to the basis of his opinion. See 

Goss v. State, 826 S.W.2d 162, 168 (Tex. Crim. App. 1992) (noting that voir dire under Rule 

705(b) is not discretionary in criminal cases).
9

function under Rule 702 has not replaced cross-examination as “the traditional and appropriate 

means of attacking shaky but admissible evidence”). Nor did it prevent counsel from moving to 

exclude Jefferies’s testimony on the ground that it was “not grounded in the methods and 

procedures of science.” See Robinson, 923 S.W.2d at 557. In fact, counsel for D.L.E.B. did 

cross-examine Jefferies about his methodologies regarding drug concentrations in hair follicles at 

a pre-trial hearing, yet never objected to the admissibility of the expert’s testimony at trial. We 

conclude that the trial court did not abuse its discretion in denying D.L.E.B.’s request for a voir 

dire examination of Jefferies outside the jury’s presence pursuant to Rule 705(b).

It is unclear whether, in addition to complaining about the court’s refusal to 

permit him to conduct a Rule 705(b) examination, D.L.E.B. is also asserting that the trial court 

erred in admitting Jefferies’s testimony at trial because it failed to meet the standard articulated 

in Robinson. In any event, any such complaint has not been preserved for appellate review. A 

party has two fundamental options to preserve a complaint concerning an expert’s testimony: 

object to the testimony before trial or object when it is offered. Guadalupe-Blanco River Auth. 

v. Kraft, 77 S.W.3d 805, 807 (Tex. 2002); Maritime Overseas Corp. v. Ellis, 971 S.W.2d 402, 

409 (Tex. 1998) (explaining that Robinson’s focus is on trial court’s discretion in admitting or 

excluding scientific evidence after party lodges objection to reliability of its opponent’s scientific 

expert testimony before trial or when evidence is offered). Here D.L.E.B. did neither.

Counsel for D.L.E.B. never objected to the admissibility of Jefferies’s testimony 

at the hearing on the motion for a finding of aggravated circumstances or at trial. Counsel also 

failed to file a motion to exclude Jefferies’s testimony on any ground, including that it was 

speculative and unreliable, and did not request a Daubert/Robinson-type hearing. The trial court 

was never asked to make a ruling on whether Jefferies’s expert testimony was admissible under 
10

Rule 702 of the Texas Rules of Evidence. See Tex. R. Evid. 702. D.L.E.B.’s request for a Rule 

705(b) hearing does not preserve a complaint about the admissibility of Jefferies’s testimony. 

See Tex. R. App. P. 33.1(a) (“To preserve a complaint for our review, a party must have 

presented to the trial court a timely request, objection, or motion that states the specific grounds 

for the desired ruling, unless such grounds are apparent from the context.”). The purpose of a 

Rule 705(b) hearing is to permit a party to conduct a voir dire examination of the expert, outside 

the presence of the jury, “directed to the underlying facts or data upon which the opinion is 

based.” See Tex. R. Evid. 705(b). This permits counsel to examine an expert to elicit evidence 

on which it may base a Rule 702 objection without the risk of the jury hearing what may later be 

deemed to be inadmissible evidence. See Alba v. State, 905 S.W.2d 581, 588 (Tex. Crim. App. 

1995) (“This ‘gatekeeping’ hearing affords a defendant the chance to voir dire the expert witness 

and determine the foundation of the expert’s opinion without fear of eliciting damaging hearsay

or other inadmissible evidence in the jury’s presence.”). The evidence elicited in such an 

examination may provide the basis for an objection to the admissibility of an expert’s testimony 

or a motion to exclude that testimony, but the request for such an examination does not itself 

constitute an objection to an expert’s testimony. Although counsel for D.L.E.B. requested an 

opportunity to examine Jefferies’s “qualifications,” he did not object to the admission of 

Jefferies’s testimony then or at trial. In fact, counsel expressly stated: “And I’m not challenging 

him at this point.” We conclude that D.L.E.B. failed to preserve a complaint that Jefferies’s

expert testimony was inadmissible.
11

CONCLUSION

D.L.E.B. has not demonstrated that the trial court abused its discretion by denying 

the request to examine Jefferies about the facts or data underlying his opinions outside the 

presence of the jury pursuant to Rule 705(b). D.L.E.B. has failed to preserve a complaint that 

Jefferies’s testimony was inadmissible under Rule 702. We therefore overrule D.L.E.B.’s sole 

appellate issue and affirm the trial court’s order terminating D.L.E.B.’s parental rights to L.J.B.
