Police officers will have an easier process to obtain surveillance warrants under legislation signed by Governor Manchin.
The bill was one of two passed during the recent special session that received Manchin's approval Wednesday.
The other measure aims to protect address information found in state records of victims of domestic abuse, sexual assault or stalking.
The surveillance bill was a response to a February state Supreme Court ruling, requiring police to obtain a warrant before wiring informants with recorders and send them into a suspect's residence.
State law had limited such warrants to five circuit judges statewide, but the new legislation allows any circuit judge or magistrate to sign off on them.
