  • ERPO = extreme risk protection order

  • a In Connecticut, prior to June 1, 2022, only law enforcement and state officials could petition for an order; thereafter, family and household members could petition for an investigation by law enforcement that can result in law enforcement petitioning for an order. The law changed after the study was completed. During the study period, duration of the ERPO was up to 1 year.

  • b In California, the standard of proof for temporary orders is “probable cause” for orders petitioned by law enforcement only and “substantial likelihood” for orders petitioned by family and law enforcement. During the study period, duration of the ERPO was up to 1 year.
