An appeal automatically stays a mandatory injunction, but not a prohibitory injunction. Here, the trial court ordered the San Bernardino Board of Supervisors to remove and replace one of its sitting members based on the trial court’s finding that the board had violated the Brown Act (Gov. Code 54950) requiring open meetings. A mandatory injunction is one that commands a change in the parties’ positions (i.e., the status quo). Exempt from the mandatory category are injunctions that prohibit the defendant from repeating in the future a violation that the trial court has found in its past conduct. The trial court’s injunction in this case is mandatory in nature. It changes the status quo Here, there is no threat of a future similar violation since there is no likelihood of a future vacancy to be filled by the same means. But the decision suggests that the Legislature may wish to revisit the issue and give trial and appellate courts more discretion to allow stays of even mandatory injunctions when needed to prevent injustice.
