Unless otherwise authorized by law, it is illegal in Nevada to intercept or attempt to intercept any wire communication unless the interception is made with the consent of at least one party to the communication and an emergency makes it impractical to obtain a court order as required by law (NV Rev. Stat. Sec. 200.620). Any person who has made an emergency interception must, within 72 hours, make a written application to the court for ratification of the interception. If this is not done, any use of the intercepted communication is unlawful. In addition, if the application is denied, any use or disclosure of the intercepted information is unlawful, and the person who made the interception must notify the sender and receiver of the communication that the communication was intercepted and that the application for ratification was denied.
In addition, Nevada law prohibits any person from intruding on the privacy of another by listening to, monitoring, or recording by any mechanical, electronic, or other listening device a private conversation. Nevada law also bars the disclosure of the conversation unless authorized to do so by one of the parties to the conversation (NV Rev. Stat. Sec. 200.650).
