RA 4200: Anti-Wiretapping Act

Summary

Republic Act No. 4200, approved 19 June 1965, prohibits the secret recording of any private communication or spoken word without the consent of all parties to the communication. It also makes inadmissible any evidence obtained in violation of the Act. Philippine jurisprudence consistently requires consent of all parties — there is no general 'one-party' or 'party-to-call' exception. Borrowers recording calls with debt collectors must understand this requirement before relying on a recording as evidence.
