The following provisions shall govern requests to seal articles which are protected by a protective order entered pursuant to Evidence Code Section 1060 or 1061:

(a) The People shall request sealing of articles reasonably expected to be filed or admitted into evidence as follows:

(1) No less than 10 court days before trial, and no less than five court days before any other criminal proceeding, the People shall file with the court a list of all articles which the People reasonably expect to file with the court, or admit into evidence, under seal at that proceeding. That list shall be available to the public. The People may be relieved from providing timely notice upon showing that exigent circumstances prevent that notice.

(2) The court shall not allow the listed articles to be filed, admitted into evidence, or in any way made a part of the court record otherwise open to the public before holding a hearing to consider any objections to the People’s request to seal the articles. The court at that hearing shall allow those objecting to the sealing to state their objections.

(3) After hearing any objections to sealing, the court shall conduct an in camera hearing with only the owner of the trade secret contained within those articles, the People’s representative, defendant, and defendant’s counsel present. The court shall review the articles sought to be sealed, evaluate objections to sealing, and determine whether the People have satisfied the constitutional standards governing public access to articles which are part of the judicial record. The court may consider testimony presented or affidavits filed in any proceeding held in that action. The People, defendant, and the owner of the trade secret may file affidavits based on the affiant’s personal knowledge to be considered at that hearing. Those affidavits are to be sealed and not released to the public, but shall be made available to the parties. The court may rule on the request to seal without taking testimony. If the court takes testimony, examination of witnesses shall not be used to obtain discovery, but shall be directed solely toward whether sealing is appropriate.

(4) If the court finds that the movant has satisfied appropriate constitutional standards with respect to sealing particular articles, the court shall seal those articles if and when they are filed, admitted into evidence, or in any way made a part of the court record otherwise open to the public. The articles shall not be unsealed absent an order of a court upon a showing of good cause. Failure to examine the court file for notice of a request to seal shall not constitute good cause to consider objections to sealing.

(b) The following procedure shall apply to other articles made a part of the court record:

(1) Where any articles protected by a protective order entered pursuant to Section 1060 or 1061 are filed, admitted into evidence, or in any way made a part of the court record in such a way as to be otherwise open to the public, the People, a defendant, or the owner of a trade secret contained within those articles may request the court to seal those articles.

(2) The request to seal shall be made by noticed motion filed with the court. It may also be made orally in court at the time the articles are made a part of the court record. Where the request is made orally, the movant must file within 24 hours a written description of that request, including a list of the articles which are the subject of that request. These motions and lists shall be available to the public.

(3) The court shall promptly conduct hearings as provided in paragraphs (2), (3), and (4) of subdivision (a). The court shall, pending the hearings, seal those articles which are the subject of the request. Where a request to seal is made orally, the court may conduct hearings at the time the articles are made a part of the court record, but shall reconsider its ruling in light of additional objections made by objectors within two court days after the written record of the request to seal is made available to the public.

(4) Any articles sealed pursuant to these hearings shall not be unsealed absent an order of a court upon a showing of good cause. Failure to examine the court file for notice of a request to seal shall not constitute good cause to consider objections to sealing.
