New York Consolidated Laws, Criminal Procedure Law - CPL § 700.35 Eavesdropping and video surveillance warrants;  manner and time of execution

1. An eavesdropping or video surveillance warrant must be executed according to its terms by a law enforcement officer who is a member of the law enforcement agency authorized in the warrant to intercept the communications or conduct the video surveillance.

2. Upon termination of the authorization in the warrant, eavesdropping or video surveillance must cease and as soon as practicable thereafter any device installed for such purpose either must be removed or must be permanently inactivated as soon as practicable by any means approved by the issuing justice.  Entry upon a private place or premise for the removal or permanent inactivation of such device is deemed to be authorized by the warrant.

3. The contents of any communication intercepted or of any observation made by any means authorized by this article must, if possible, be recorded on tape or wire or other comparable device.  The recording of the contents of any such communication or observation must be done in such way as will protect the recording from editing or other alterations.

4. In the event an intercepted communication is in a code or foreign language, and the services of an expert in that foreign language or code cannot reasonably be obtained during the interception period, where the warrant so authorizes and in a manner specified therein, the minimization required by subdivision seven of section 700.30 of this article may be accomplished as soon as practicable after such interception.

5. A good faith reliance by a provider of a wire or electronic communication service upon the validity of a court order issued pursuant to this article is a complete defense against any civil cause of action or criminal action based solely on a failure to comply with this article.
