The measure he’s proposing is known as an extreme risk protection order (ERPO) law, which would allow relatives to ask a judge to determine whether a troubled family member should temporarily lose access to firearms. After a hearing, a court order could prohibit someone from having firearms for as long as a year, with a chance to ask for an early expiration, the possibility of renewal after a year, and a requirement their firearms are returned within one business day once the order expires.
