Whenever any State or political subdivision thereof intends to enter into evidence or otherwise use or disclose in any trial, hearing, or other proceeding in or before any court, department, officer, agency, regulatory body, or other authority of a State or a political subdivision thereof against an aggrieved person any information obtained or derived from a physical search pursuant to the authority of this subchapter, the State or political subdivision thereof shall notify the aggrieved person, the court or other authority in which the information is to be disclosed or used, and the Attorney General that the State or political subdivision thereof intends to so disclose or so use such information.

In making this determination, the court may disclose to the aggrieved person, under appropriate security procedures and protective orders, portions of the application, order, or other materials relating to the physical search, or may require the Attorney General to provide to the aggrieved person a summary of such materials, only where such disclosure is necessary to make an accurate determination of the legality of the physical search.

If the United States district court pursuant to subsection (g) determines that the physical search was not lawfully authorized or conducted, it shall, in accordance with the requirements of law, suppress the evidence which was unlawfully obtained or derived from the physical search of the aggrieved person or otherwise grant the motion of the aggrieved person. If the court determines that the physical search was lawfully authorized or conducted, it shall deny the motion of the aggrieved person except to the extent that due process requires discovery or disclosure.
