TITLE 1. CODE OF CRIMINAL PROCEDURE
CHAPTER 18. SEARCH WARRANTS
This article was amended by the 85th Legislature. Pending publication of the current statutes, see H.B. 3237 and H.B. 1727, 85th Legislature, Regular Session, for amendments affecting this section.
Art. 18.01. SEARCH WARRANT. (a) A "search warrant" is a written order, issued by a magistrate and directed to a peace officer, commanding him to search for any property or thing and to seize the same and bring it before such magistrate or commanding him to search for and photograph a child and to deliver to the magistrate any of the film exposed pursuant to the order.
(b) No search warrant shall issue for any purpose in this state unless sufficient facts are first presented to satisfy the issuing magistrate that probable cause does in fact exist for its issuance. A sworn affidavit setting forth substantial facts establishing probable cause shall be filed in every instance in which a search warrant is requested. Except as provided by Article 18.011, the affidavit is public information if executed, and the magistrate's clerk shall make a copy of the affidavit available for public inspection in the clerk's office during normal business hours.
Art. 18.011. SEALING OF AFFIDAVIT. (a) An attorney representing the state in the prosecution of felonies may request a district judge or the judge of an appellate court to seal an affidavit presented under Article 18.01(b). The judge may order the affidavit sealed if the attorney establishes a compelling state interest in that:
(1) public disclosure of the affidavit would jeopardize the safety of a victim, witness, or confidential informant or cause the destruction of evidence; or
(2) the affidavit contains information obtained from a court-ordered wiretap that has not expired at the time the attorney representing the state requests the sealing of the affidavit.
(b) An order sealing an affidavit under this section expires on the 31st day after the date on which the search warrant for which the affidavit was presented is executed. After an original order sealing an affidavit is issued under this article, an attorney representing the state in the prosecution of felonies may request, and a judge may grant, before the 31st day after the date on which the search warrant for which the affidavit was presented is executed, on a new finding of compelling state interest, one 30-day extension of the original order.
(c) On the expiration of an order issued under Subsection (b) and any extension, the affidavit must be unsealed.
(d) An order issued under this section may not:
(1) prohibit the disclosure of information relating to the contents of a search warrant, the return of a search warrant, or the inventory of property taken pursuant to a search warrant; or
(2) affect the right of a defendant to discover the contents of an affidavit.
