An Act amending Title 42 (Judiciary and Judicial Procedure) of the Pennsylvania Consolidated Statutes, in commencement of proceedings, further providing for arrest without warrant.

HB 449 requires Pennsylvania police officers to issue a warning or citation ordering individuals to stop specific minor unlawful conduct before making an arrest without a warrant. It applies to offenses like disorderly conduct, public drunkenness, obstructing highways, and liquor violations under Title 18. The bill mandates that officers must first warn individuals to cease the conduct, and only arrest if they refuse or fail to comply. Additionally, police departments must establish written guidelines for officers before implementing these warrantless arrests. The law takes effect 60 days after enactment.
