This is a medical malpractice case founded on diversity, governed by Texas substantive law, and presenting two issues. The first issue is whether the trial court abused its discretion by denying plaintiffs’ motion for a new trial when the jury, after finding the defendant liable, disregarded the objective and uncontroverted evidence by awarding plaintiff no recovery for certain elements of damages. The second issue is whether the trial court abused its discretion by refusing to submit a jury interrogatory on exemplary damages when the pleadings and evidence raised the issue of gross negligence. We conclude that the trial court abused its discretion in both instances; therefore, we reverse and remand the case for a new trial.
Background
This case began in November 1982, when appellee Dr. James G. Taylor prescribed birth control pills for appellant Lois Jackson. In May 1986, Ms. Jackson was hospitalized with bleeding liver tumors, which were allegedly caused by the birth control pills. Ms. Jackson’s case against Dr. Taylor was tried to a jury, and the jury found that Dr. Taylor was negligent and that his negligence was a proximate cause of Ms. Jackson’s injuries. The jury awarded Ms. Jackson $20,719.85 in total damages, which corresponded exactly to her past medical expenses as stipulated by the parties. Ms. Jackson had also sought damages for fu *797 ture medical expenses; past pain, suffering, and mental anguish; past physical impairment; past loss of earnings; future loss of earning potential; and Mr. Jackson had claimed damages for loss of consortium. In light of the jury’s curious damage award, Ms. Jackson requested a new trial on the issue of damages. The trial court denied her request. Ms. Jackson also requested a jury interrogatory on exemplary damages, but the trial court refused this request as well. She now appeals, complaining of these rulings.
The Jury’s Damage Award
Considering Ms. Jackson’s first point of error, the ultimate issue is whether the trial court abused its discretion by refusing to grant her motion for a new trial.
See Franks v. Associated Air Center, Inc.,
Federal law governs the sufficiency of evidence to warrant a new trial,
Jones v. Wal-Mart Stores, Inc.,
The record indicates that the jury was instructed to consider seven elements of damages. The jury award of $20,719.85 corresponds exactly to the stipulated amount of past medical expenses. Ms. Jackson argues on appeal that she presented “objective and uncontroverted” evidence on all seven elements of damages and that she is entitled to have an award for each element. Yet, some elements of her damages, such as those relating to pain and suffering are, by their nature, subjective. The jury is entitled to weigh the credibility of the evidence and cannot be compelled to award damages if it concludes that the evidence is untrustworthy.
See Tatum v. Huddleston,
At least two of Ms. Jackson’s elements of damages, however, are objective and were objectively proved. The record indicates that Ms. Jackson’s past physical impairment and her past lost earnings were supported by objective and uncontroverted evidence. Under Texas law, the jury may not ignore this evidence. Under federal law, a reasonable jury could not have concluded otherwise than that Ms. Jackson was entitled to an award for these elements of damages. It is thus apparent that Ms. Jackson has satisfied both the Texas “objective and uncontroverted” test and the federal sufficiency standard on two elements of her damages for which she was awarded no recovery, and thus, we are compelled to find that the trial court erred by denying her motion for a new trial.
*798 The Exemplary Damages Instruction
Here, as with the motion for a new trial, the ultimate issue is whether the trial court abused its discretion by refusing to grant Ms. Jackson’s request for a jury instruction on exemplary damages.
See Bryan v. Cargill, Inc.,
State law determines that evidence which is relevant to the issue of exemplary damages. Under Texas law, exemplary damages in a medical malpractice case are permissible when the evidence shows gross negligence — “that entire want of care which would raise the belief that the act or omission complained of was the result of a conscious indifference to the right or welfare of the person or persons affected by it.”
McPhearson v. Sullivan,
The record indicates that Ms. Jackson’s pleadings contained allegations of gross negligence and that the video deposition of Dr. William A. Cook, plaintiff’s expert, was presented to the jury. In his deposition and after being informed of the McPhearson definition of gross negligence, Dr. Cook testified that in his opinion Dr. Taylor was grossly negligent. Dr. Cook went on to identify the particular acts and omissions that he felt demonstrated Dr. Taylor’s conscious indifference to the welfare of Ms. Jackson. The record also contains evidence tending to rebut Dr. Cook’s opinion — most notably that Ms. Jackson purchased over 1000 birth control pills in a period of time when less than 200 were prescribed. 1 But Dr. Taylor does not point to any direct rebuttal of Dr. Cook’s opinion nor does our review of the record reveal any direct rebuttal. Based on the record, we must conclude that there was sufficient evidence to submit a jury interrogatory on exemplary damages and that the trial court erred by refusing to submit Ms. Jackson’s requested jury interrogatory; therefore, we must reverse the judgment of the trial court and remand this case for a new trial.
Conclusion
We hold that, under Texas law, a jury may not disregard objective and uncontro-verted evidence concerning elements of plaintiff’s damages; therefore, we must find that the trial court abused its discretion by denying plaintiff’s request for a new trial. We also hold that, under Texas substantive and federal procedural law, if both the pleadings and evidence raise the issue of gross negligence, a jury interrogatory on exemplary damages is required; thus, we must find that the trial court abused its discretion by refusing to submit a jury interrogatory on exemplary damages. Accordingly, we REVERSE the decision of the trial court and REMAND the case for a new trial on both liability and damages.
REVERSED and REMANDED.
Notes
. Despite this circumstance, Dr. Taylor apparently did not plead contributory negligence.
