IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION FOUR

CLINTON MIELKE, Plaintiff and Appellant, A170721 v. (Alameda County THE REGENTS OF THE Super. Ct. No. RG20081227) UNIVERSITY OF CALIFORNIA et al., Defendants and Respondents.

Plaintiff Clinton Mielke, Ph.D., a data scientist, sued his former employer, the Regents of the University of California (the Regents), and three individual defendants (Michael Blum, M.D.; Rachael Callcut, M.D.; and Robert Rogers, Ph.D.), alleging he was terminated in retaliation for whistleblowing activities. The trial court granted summary judgment for defendants, finding Mielke could not establish his protected activity was a contributing factor in the termination decision. On appeal, Mielke challenges the court’s summary judgment ruling, as well as its rulings denying Mielke’s request for a continuance of the summary judgment hearing, denying his motion for a new trial, and granting only limited relief when Mielke sought to vacate the summary judgment order. Applying de novo review, we conclude the court erred in granting summary

1 judgment, and we will reverse the judgment. We therefore need not address Mielke’s appellate challenges to the court’s rulings on his motions for a continuance, for a new trial, and to vacate the summary judgment order. I. BACKGROUND In summarizing the background of this appeal, we take the relevant facts from the record that was before the trial court when it ruled on defendants’ summary judgment motion. (State Dept. of Health Services v. Superior Court (2003) 31 Cal.4th 1026, 1034–1035.) We grant defendants’ motion to strike the declaration that Mielke submitted in this court, in which he seeks to present additional evidence on appeal, and we will disregard the portions of Mielke’s appellate briefs that rely on that declaration. We also do not consider evidence that Mielke belatedly presented in the trial court (such as with his motion for new trial), as that evidence was not part of the record on which the court based its summary judgment ruling. A. Mielke’s Employment and Termination Mielke began working for the Center for Digital Health Innovation (CDHI) at the University of California, San Francisco (UCSF) in the summer of 2017. CDHI builds algorithms that partner companies license from the university. Mielke was supervised by Callcut, who served as CDHI’s director of data science and advanced analytics and was also an associate professor of surgery. Mielke’s second-level supervisor was Blum, a cardiologist who was UCSF’s chief digital transformation officer and associate vice chancellor for informatics. Mielke also worked with Rogers, a physicist who was not a university employee but who worked as a consultant beginning in June 2018 through a contract with the university. Callcut and Blum state that, in early 2019, they believed Mielke’s work performance was inconsistent and his behavior inappropriate. They received complaints that Mielke was not forthcoming about the status of his work,

2 made insulting comments about coworkers, and discussed his bodily functions. In mid-February 2019, Callcut met with Mielke and discussed his performance evaluation for his work in 2018. The evaluation was generally positive, although with ratings lower than those received by Mielke’s peers. Callcut told Mielke there was a perception he was withholding work and was not a collaborative team member. According to Callcut, by March 2019, Mielke had become more disruptive and unreliable. Callcut contacted the university’s human resources (HR) department and received guidance about initiating a disciplinary process. On March 18, 2019, Callcut met with Mielke and counseled him about his performance, including productivity expectations, workplace behavior and teamwork, and Mielke’s perception he was not receiving appropriate credit for his work. Callcut states that Mielke became increasingly disruptive after the March 18, 2019 meeting. On March 22, 2019, Callcut and Blum met with Mielke, counseled him about performance and behavior issues, and issued him a written letter of warning. The parties state that, on March 24, 2019, Mielke submitted a written “whistleblower” complaint to a designated university official. As described by the parties, Mielke’s complaint alleged a corporate partner, General Electric (GE), had been misled about the status of a project on which CDHI was working. Mielke’s written complaint about this alleged conduct is not in the record that was before the trial court when it ruled on the summary judgment motion, but defendants stated in their motion that they accepted for purposes of the motion that Mielke engaged in protected whistleblowing activity. As we discuss below, Mielke’s supervisors, Callcut and Blum,

3 declared in support of summary judgment that they were not aware of Mielke’s protected activity at this time. On May 8, 2019, Mielke was placed on paid investigatory leave. According to Callcut, Mielke’s negative behaviors, which had briefly improved after the March 22, 2019 meeting, had since continued. Mielke was unproductive and was also disrupting the ability of others to complete their work. On July 22, 2019, Blum and Callcut held an investigatory meeting with Mielke to discuss his behavior and work performance issues. Callcut states that, after this meeting, she decided to recommend that Mielke be terminated. Blum agreed with the decision. After working with HR to compile the necessary documentation, Callcut issued a Notice of Intent to Terminate (NOIT) to Mielke on September 16, 2019. In May 2020, following completion of the Skelly review process (in which the review officer found the termination decision was well supported), Blum sent Mielke a notice of termination. B. Procedural Background 1. Mielke’s Lawsuit Mielke filed the present action in November 2020, asserting a cause of action for whistleblower retaliation under Government Code section 8547.10. Mielke initially named as defendants the Regents, Blum, and Callcut; he later added Rogers as a defendant. Mielke alleged he suffered retaliation because he identified potential fraud connected with the university’s GE contract, specifically that CDHI accepted funding from GE, failed to report Mielke’s work as progress, and instead falsely reported other work as the first results on the project. Mielke alleged that on or about March 6, 2019, his colleague Scott Hammond told him that a prototype developed by Mielke

4 was shown to GE competitor Philips to solicit an alternate funding source. According to Mielke, Hammond was fired the next day. Mielke alleged that, on March 13, 2019, he told Rogers that he had been discussing suspected “foul play” with someone in HR, and was debating whether he should “blow the whistle.” Mielke alleged this conversation with Rogers was protected whistleblowing activity, as was his March 24, 2019 written “whistleblower report.” He alleged all defendants knew about his protected activity before he was terminated. Mielke alleged that, as a result of his whistleblowing, he was subjected to disciplinary meetings, investigatory leave, a criminal investigation based on false allegations about images on his laptop (after which he was cleared of wrongdoing), and, ultimately, termination. 2. Defendants’ Summary Judgment Motion In May 2022, defendants moved for summary judgment, but they later took the motion off calendar.
