Ninth Circuit Revives Fired Kaiser Employee's Religious Objection Lawsuit Over COVID Vaccine Mandate

Twenty Years, Then Fired

Mimi Weiss worked for The Permanente Medical Group, part of Kaiser Permanente, for two decades. In August 2021, Kaiser rolled out a mandatory COVID-19 vaccination policy for employees, including remote workers like Weiss, according to HR Dive. Employees had until September 30 to show proof of vaccination or get an exemption. Miss the deadline and you faced 60 days of unpaid leave, then termination, per HR Dive's account of the policy.

Weiss, who describes herself as a Christian Jew, requested a religious exemption within weeks of the mandate, according to Becket, the religious liberty legal group that represented her. She cited Deuteronomy 14:1 and 1 Corinthians 6:19 and said her faith required her to keep her body "uncontaminated," according to HCA Mag's reporting on the court record. Kaiser approved the exemption.

Then Kaiser Changed Course

Three weeks later, Kaiser reopened the review. The company said it had noticed a pattern of religious exemption requests using identical language and worried some were not legitimate, according to ZeroHedge's summary of the Ninth Circuit opinion. Kaiser asked employees, including Weiss, to resubmit in their own words.

Kaiser then sent Weiss new questions, including whether she'd ever taken medications, when she last did, and why her faith blocked the COVID vaccine specifically but not other medicine, according to Becket. Weiss answered some questions but refused to detail her medication history, calling it a privacy matter, according to HR Dive.

Kaiser revoked her exemption, placed her on unpaid leave, and fired her for noncompliance with the mandate. Weiss sued.

The Legal Question: How Much Do You Have to Say?

A federal district judge ruled against Weiss in 2024, finding she hadn't given Kaiser sufficient notice that a genuine religious conflict existed, according to ZeroHedge. The district court reasoned that treating her general objections as sufficient notice would create what it called a "limitless excuse" for dodging workplace rules, according to HR Dive's account of the lower court's reasoning.

On July 24, 2026, a unanimous three-judge Ninth Circuit panel reversed that ruling. Circuit Judge Danielle Forrest, writing for the court, said Weiss "plausibly alleged that she provided notice of her religious conflict with the mandate in her initial request for a religious exemption," according to ZeroHedge.

The panel's core holding: under Title VII of the 1964 Civil Rights Act and California's Fair Employment and Housing Act, an employee only needs to give an employer "enough information about her religious needs to permit the employer to understand the existence of a conflict." Demanding more, Judge Forrest wrote, "would permit an employer to delve into the religious practices of an employee in order to determine whether religion mandates the employee's adherence," according to both ZeroHedge and Becket.

The court drew a distinction between two separate legal questions that Kaiser's lawyers had blurred together, according to HCA Mag: whether an employee adequately flagged a religious conflict, and whether that religious belief is sincere. Those are different inquiries under the law, the panel said, and the notice requirement can't be stretched to double as a sincerity test.

The judges also pointed to Kaiser's own conduct as evidence. The company's initial approval of Weiss's exemption showed Kaiser itself understood she had raised a religious objection, according to HR Dive. Nothing in the record, the court noted, showed Kaiser ever actually doubted that her belief was sincere, according to HR Dive's summary of the opinion.

Kaiser's strongest argument, and the one the district court had originally accepted, deserves a fair hearing. Employers reopening exemption reviews after spotting copy-pasted requests aren't necessarily acting in bad faith. Verifying that religious accommodation requests aren't just a workaround for people who simply don't want a vaccine is a legitimate employer concern, and Kaiser said it was worried specifically about a pattern of near-identical submissions, according to HCA Mag. The Ninth Circuit didn't say that concern was illegitimate. It said Kaiser used the wrong tool to address it, conflating a notice requirement with a sincerity test the law treats separately.

What the Ruling Does and Doesn't Do

HCA Mag is explicit that this decision does not resolve whether Kaiser actually discriminated against Weiss. It only revives her claims and sends the case back to the district court, where the merits are still undecided. The panel also issued a separate 2-1 memorandum disposition on Weiss's state law privacy claims tied to the medication questions, according to Becket.

HR Dive flags that the ruling sits alongside a 2025 Ninth Circuit decision, Detwiler v. Mid-Columbia Medical Center, where the same court ruled against an employee whose objection to a testing alternative was deemed "personal and secular" rather than religious. Read together, the two rulings show the Ninth Circuit drawing a fairly precise line: genuine religious objections get protection when adequately flagged, but objections without a religious basis don't.

Weiss, in a statement provided to Becket, said she "never imagined my faith would end up costing me my job" and that she wasn't asking for special treatment, just "the freedom to live according to my conscience."

The case now returns to the U.S. District Court, where Kaiser will have to defend its firing decision on the merits, including whatever justification it offers beyond the notice question the Ninth Circuit just resolved against it. No trial date has been set in the sources reviewed.
