IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA THIRD APPELLATE DISTRICT (San Joaquin) ----

JAYDEN A.G., a Minor, etc., C096920

Plaintiff and Appellant, (Super. Ct. No. STKCVUNPI20180005509) v.

LINCOLN UNIFIED SCHOOL DISTRICT et al.,

Defendants and Respondents.

Plaintiff Jayden Galbert, through his mother and guardian ad litem Shynelle Jones, brought a personal injury action against defendants Lincoln Unified School District, its superintendent, the principal of Lincoln High School, and a football coach at the school. In August 2017, when he was 13 years old, Galbert participated in the school’s football tryouts on a day when the temperature exceeded 100 degrees. At the end of the tryouts, Galbert collapsed and was later hospitalized and treated for exertional heatstroke. Galbert sued defendants, alleging that he suffered permanent partial disabilities as a result. After years of litigation, Galbert proceeded to trial on a single cause of action that

1 his complaint pleaded as “Reckless/Gross Negligence (CACI 425).” (Some capitalization omitted.) The jury found defendants not liable. Galbert, who is no longer a minor, appeals, contending primarily that the trial court erred in construing the operative complaint as alleging only “gross” negligence, not “ordinary” negligence, and requiring him to prove that heightened form of negligence.1 He additionally argues that the trial court misinstructed the jury that certain guidance and policy documents did not establish a “mandatory duty” or “mandatory standard of care,” which error he contends was exacerbated by the court’s sustaining of a witness’s assertions of an unspecified “privilege” in connection with the witness’s invocation of his Fifth Amendment right against self-incrimination. Galbert also claims that the trial court erred in failing to exclude statements that methamphetamine was in his system on the date of the incident when it undisputedly was not. And he argues that these asserted errors, when viewed together, were cumulatively prejudicial, warranting a new trial. Finding no grounds for reversal in any of these claims, either individually or collectively, we affirm. BACKGROUND The following events, as described in the trial testimony, gave rise to Galbert’s suit. On August 1, 2017, Galbert participated in tryouts for the freshman football team at Lincoln High School in Stockton, where he was about to start high school. The week before, the National Weather Service had issued an excessive heat watch, warning of widespread triple-digit temperatures across central California, including Stockton, over the following week. Area heat advisories issued on July 31st and August 1st warned of highs between 98 and 108 degrees in locations at Stockton’s elevation and advised staying hydrated, staying out of the sun, and rescheduling strenuous activities to the morning or evening. The advisories also warned of the possibility of heat-related

2 illnesses. The school’s athletic director and defendant John James, the coach of the freshman football team, were aware that it would be hot but did not modify or reschedule the tryouts. Several days before the tryouts, Galbert was prescribed Adderall. Galbert took the medication on the days leading up to the tryouts, including on the morning of August 1, 2017. On August 1st, the temperature near Lincoln High School reached at least 101 degrees. The tryouts that day started at 2:30 p.m. on an Astroturf field, which was hotter than a grass field. The players participated in various drills with no contact, no pads, and no helmets. Around 3:30 or 4:00 p.m., they walked to a practice field at a nearby middle school. There, they walked through plays for some time, during which Galbert was standing to the side, and then finished with conditioning. Coach James testified that the players ran 100 yards six times, with short breaks in between. Galbert testified that they ran 100 yards ten times, running each as fast as they could. Around 4:10 p.m. or later, the players gathered in front of James, each on one knee, for a closing huddle. James testified that, during the huddle, Galbert’s head dropped, he went limp, and then “he kind of rolled over” onto his back. James recalled that Galbert got back up as soon as he went to check on him, saying he was okay, just hot. In a video-recorded deposition played for the jury, one of the other players testified that Galbert had “passed out” for more than two minutes. James disagreed with that testimony and stated that he did not believe Galbert ever lost consciousness. James and another player walked Galbert over to sit on a bucket in the shade and poured water on him because he said he was hot. Galbert called his grandmother to explain where to come to pick him up. James testified that Galbert was speaking normally to her but she was not understanding where he was located, so James took the phone and spoke with her. According to James, he told Galbert’s grandmother that Galbert had fallen over and said he was hot. James explained

3 the pickup location to her. Galbert’s grandmother relayed the information to a family friend who was scheduled to pick up her grandson. James recalled Galbert again saying he was fine, “just hot.” James and the athletic director testified that the ambient temperature was over 100 degrees at the time of Galbert’s collapse. Galbert’s climate expert testified that, during the tryouts, players likely would have experienced a heat index of over 100 degrees and, at the time of Galbert’s collapse, an index of over 109 degrees. After calling his grandmother, Galbert took a large drink of water and then vomited. A few minutes later, the family friend arrived, and, according to James’s testimony, James described what had happened and suggested that the friend take Galbert to the hospital as a precaution. At James’s suggestion, the friend drove his van onto the field, and Galbert “crawled” in. After they left, James called Galbert’s mother and told her what had happened. According to James, he suggested that Galbert be taken to the hospital; but according to Galbert’s mother, James did not suggest that or convey any sense of emergency until he called her a second time and suggested taking him to urgent care. Later that evening, Galbert was taken to a local hospital by ambulance because he was hyperventilating, speaking in a childlike manner, and could not focus his vision. He was later airlifted to another hospital, where he was diagnosed with heatstroke and treated in the intensive care unit for a few days. Galbert filed suit in May 2018. Pretrial litigation continued for four years, with Galbert asserting variously styled causes of action for gross negligence across four successive complaints. After the trial court denied defendants’ motion for summary judgment, the case proceeded to trial, and in May 2022, a divided jury found defendants

4 were not grossly negligent. After an unsuccessful motion for a new trial, Galbert filed this timely appeal from the judgment entered in favor of defendants.2 DISCUSSION I. Galbert’s principal contention on appeal is that the trial court erred in construing his complaint as alleging only a cause of action for gross negligence, not ordinary negligence, and by preventing him at various stages of the litigation from pursuing a theory of ordinary negligence.
