The court may enter a temporary restraining order or an order for preliminary injunctive relief in a civil action concerning prison conditions to the extent otherwise authorized by law. Preliminary injunctive relief shall be narrowly drawn, extend no further than necessary to correct the harm the court finds requires preliminary relief, and be the least intrusive means necessary to correct that harm. The court shall give substantial weight to any adverse effect on public safety or the operation of the criminal justice system caused by the preliminary relief in tailoring the preliminary relief. Preliminary injunctive relief shall automatically expire 90 days after the preliminary injunctive order is entered, unless the court makes the findings required under section 5517(1) for the entry of prospective relief and makes the order final before the expiration of the 90-day period.
