evidence: Even though Los Angeles Unified dropped its COVID vaccine mandate for school staff almost a year ago, a lawsuit accusing the district of violating workers’ rights can still move forward, the U.S. 9th Circuit Court of Appeals ruled on Friday. The 2-1 ruling by a pair of federal judges appointed by former President Donald Trump revives a case that a lower court had dismissed. It also counters recent rulings by courts — including the 9th Circuit — that tossed lawsuits challenging expired COVID-19 rules on the grounds that the policies were no longer in effect. [...] In 2022, a 9th Circuit panel of 11 judges ruled that a lawsuit against Gov. Gavin Newsom over COVID-related school closures couldn’t move forward since schools had reopened and "there was no longer a live controversy." Another ruling, last month in a California state appeals court, drew a similar conclusion in a lawsuit against Newsom over COVID safety guidelines.
