Intercept Warrant Law and Legal Definition

An intercept warrant is a warrant giving permission to conduct electronic surveillance, or wiretapping, such as listening to conversations on a phone line. Laws vary by state, and in some states, a court can issue an oral order for an interception without a warrant, based upon probable cause shown that a crime has been or will be committed, and later issue the warrant which refers to the granting of the oral order and made retroactive to the time of the oral order.
