reports and notice.

1. An eavesdropping or video surveillance warrant may require reports to be made to the issuing justice showing what progress has been made toward achievement of the authorized objective and the need for continued eavesdropping or video surveillance. Such reports shall be made at such intervals as the justice may require.

2. Immediately upon the expiration of the period of an eavesdropping or video surveillance warrant, the recordings of communications or observations made pursuant to subdivision three of section 700.35 must be made available to the issuing justice and sealed under his directions.

3. Within a reasonable time, but in no case later than ninety days after termination of an eavesdropping or video surveillance warrant, or expiration of an extension order, except as otherwise provided in subdivision four, written notice of the fact and date of the issuance of the eavesdropping or video surveillance warrant, and of the period of authorized eavesdropping or video surveillance, and of the fact that during such period communications were or were not intercepted or observation were or were not made, must be served upon the person named in the warrant and such other parties to the intercepted communications or subjects of the video surveillance as the justice may determine in his discretion is in the interest of justice. Service reasonably calculated to give affected parties the notice required by this subdivision shall be effected within the time limits provided for herein and in a manner prescribed by the justice. The justice, upon the filing of a motion by any person served with such notice, may in his discretion make available to such person or his counsel for inspection such portions of the intercepted communications or video surveillance, applications and warrants as the justice determines to be in the interest of justice.

4. On a showing of exigent circumstances to the issuing justice, the service of the notice required by subdivision three may be postponed by order of the justice for a reasonable period of time. Renewals of an order of postponement may be obtained on a new showing of exigent circumstances.
