22 U.S. Code § 6725 - Warrants
The United States Government shall seek the consent of the owner or the operator, occupant, or agent in charge of the premises to be inspected prior to any inspection referred to in section 6724(a) of this title. If consent is obtained, a warrant is not required for the inspection. The owner or the operator, occupant, or agent in charge of the premises to be inspected may withhold consent for any reason or no reason. After providing notification pursuant to subsection (b), the United States Government may seek a search warrant from a United States magistrate judge. Proceedings regarding the issuance of a search warrant shall be conducted ex parte, unless otherwise requested by the United States Government.
For any routine inspection conducted on the territory of the United States pursuant to Article VI of the Convention, where consent has been withheld, the United States Government shall first obtain an administrative search warrant from a judge of the United States. The United States Government shall provide to the judge of the United States all appropriate information supplied by the Technical Secretariat to the United States National Authority regarding the basis for the selection of the plant site, plant, or other facility or location for the type of inspection sought. The United States Government shall also provide any other appropriate information available to it relating to the reasonableness of the selection of the plant, plant site, or other facility or location for the inspection.
A warrant issued under paragraph (2) shall specify the same matters required of an affidavit under that paragraph. In addition to the requirements for a warrant issued under this paragraph, each warrant shall contain, if known, the identities of the representatives of the Technical Secretariat conducting the inspection and the observers of the inspection and, if applicable, the identities of the representatives of agencies or departments of the United States accompanying those representatives.
For any challenge inspection conducted on the territory of the United States pursuant to Article IX of the Chemical Weapons Convention, where consent has been withheld, the United States Government shall first obtain from a judge of the United States a criminal search warrant based upon probable cause, supported by oath or affirmation, and describing with particularity the place to be searched and the person or things to be seized.
