On page 50, footnote 12: The sentence beginning “UCSF’s statement is presumably referring to the Pride Hall space . . . ,” is modified to read: UCSF’s statement is presumably referring to the Pride Hall space—which it found adequate but which Chorba rejected— while also referencing Chorba’s opinion that the BCH Oakland space is inadequate for his needs.

1 There is no change in the judgment.

The petition for rehearing is denied.

JOHN CHORBA, Plaintiff and Appellant, A172615 v. THE REGENTS OF THE (San Francisco City & County UNIVERSITY OF CALIFORNIA, Super. Ct. No. CPF-24-518678) Defendant and Respondent.

Plaintiff and appellant Dr. John Chorba has long been at odds with defendant and respondent University of California San Francisco (UCSF) regarding the adequacy of the research laboratory facilities and equipment afforded him. The instant matter arises from the denial of two grievances, which he judicially challenged by way of a petition for traditional and administrative mandamus. (Code Civ. Proc., §§ 1085, 1094.5.) 1 The trial court denied both forms of writ relief. Dr. Chorba raises four issues on appeal: the trial court applied an incorrect standard in rejecting his administrative mandamus claim; the administrative record does not support the denial of his grievances; the

otherwise specified.

1 grievance process was unfair and violated his due process rights; and the trial court erred in denying traditional mandamus relief, ruling UCSF does not have “a clear, mandatory, ministerial duty” to provide him with the laboratory facilities and equipment he seeks. We affirm. BACKGROUND Defendant and respondent Regents of the University of California (the Regents) own and operate UCSF, a medical complex, research center, and professional school in San Francisco. (Regents of University of California v. Superior Court (2024) 102 Cal.App.5th 852, 856.) Dr. Chorba is an associate professor in residence in the Division of Cardiology at Zuckerberg San Francisco General Hospital (ZSFG), within the Department of Medicine. He is a board-certified clinical cardiologist and a research-based physician-scientist. Since he has been affiliated with UCSF, Dr. Chorba has received grant funding for his research from several entities, including the National Institutes of Health (NIH). UCSF officials participated in the preparation of the NIH grant applications, certifying “the organization will comply with all applicable assurances and certifications referenced in the application . . . [and] the applicant organization has the ability to provide appropriate administrative and scientific oversight of the project and agrees to be fully accountable for the appropriate use of any funds awarded and for the performance of the grant-supported project or activities resulting from the application.” (NIH Grants Policy Statement, § 2.3.6 https://grants.nih.gov/grants/policy/nihgps/html5/section_2/2.3.6_legal_implic ations_of_applications.htm [as of May 8, 2026 ]; see id., § 2.1.2 https://grants.nih.gov/grants/policy/nihgps/html5/section_2/2.1.2_recipient_st aff.htm [as of May 8, 2026].)

2 UCSF has more than 20 locations throughout San Francisco and beyond. Research is conducted at several main locations, including its Mission Bay and Parnassus campuses, and ZSFG. Space is controlled by the Chancellor, who has delegated the authority to govern and reallocate existing space to the UCSF Space Committee. The committee includes the deans of the four professional schools and representatives of the Academic Senate, and is co-led by the Executive Vice Chancellor and Provost, and the Senior Vice Chancellor, Finance and Administration. At the start of his faculty appointment, Dr. Chorba’s research was conducted in the laboratory of his mentor, Dr. Kevan Shokat, located at UCSF’s Mission Bay Campus. In 2021, when Chorba received several NIH “RO1” grants, he required additional space. But none was available at ZSFG. Dr. Powe, the Chief of Medicine at ZSFG, contacted the Cardiovascular Research Institute (CVRI) to provide temporary research space for Chorba until a new research building (Pride Hall) opened at ZSFG. The RO1 grant applications, which had been executed by UCSF staff in 2020, described the research environment at UCSF generally and stated Dr. Chorba’s “research will be performed in the laboratory of Prof. Kevan Shokat on the UCSF Mission Bay Campus until his transition to independence is complete.” An October 2020 letter of support from UCSF for one of Dr. Chorba’s RO1 grants stated: “Regarding laboratory space, by the time of activation of this award, John will be provided the appropriate independent laboratory space for his staff in the vicinity of his mentor, Dr. Shokat, to facilitate his transition to independence. In 2023, we will open a state-of-the-art Research Building at [ZSFG], where we will consolidate laboratory research on the campus.” The letter went on to state that Chorba’s research program had

3 been included in the planning for the new research building and Shokat would continue to provide Chorba access to his laboratory and resources. The First MOU In June 2021, the Director of CVRI prepared a memorandum of understanding which he signed, as did Dr. Chorba and representatives of ZSFG and UCSF. Chorba claims he signed the document because he had no other choice, and not because he agreed with its terms. The MOU stated in pertinent part: “This is to memorialize our agreement regarding a short-term loan of space from CVRI to ZSFG for the purpose of providing laboratory space and office space to support the research program of Dr. John Chorba until the new UCSF Research and Academic Building at ZSFG opens, estimated in early 2023.” According to the MOU, no renovations to the CVRI space would be undertaken, and “all loaned space will be returned to CVRI in good condition upon being vacated.” Further, while Chorba occupied the loaned space, ZSFG and CVRI agreed to “split indirect cost return for Dr. Chorba’s grants which is an exceptional request and which is approved only for the short period of time of this agreement.” Chorba acknowledges the lab space provided pursuant to this MOU was suitable for his needs. As the date for the opening of Pride Hall neared, Dr. Chorba expressed a preference to stay at CVRI, and it was suggested he apply through an open search application for membership in the Institute. He did so but was not selected.
