evidence: A California lawsuit suing the state over a COVID-era vaccine mandate received new life on Friday after the Ninth Circuit Court of Appeals overturned a lower court's dismissal of the lawsuit. The lawsuit targeted Los Angeles schools that imposed a vaccine mandate on its workers. Attorneys for the schools had argued that the lawsuit was moot given the end of the mandate in 2023. The Ninth Circuit disagreed, ruling 2-1 that the workers could move forward with the case. [...] The ruling comes roughly a year after California reversed course on a vaccine mandate for students. That move came as part of a wider rollback of Gov. Gavin Newsom's expansive COVID-19 restrictions.
