; and (2) limit, notwithstanding any other provision of law, in whole or in part, the disclosure of information relating to the basis for carrying out a covered procurement action. (b) Determination and notification The head of an executive agency may exercise the authority provided in subsection (a) only after— (1) obtaining a joint recommendation by the senior procurement executive and chief information officer of the agency, or such other officials of the agency as the head of the agency considers appropriate, that there is a significant supply chain risk in a covered procurement; (2) making a determination in writing, in unclassified or classified form, that— (A) use of the authority under subsection (a)(1) is necessary to protect national security or the public interest by reducing supply chain risk; and (B) in a case where the head of the agency plans to limit disclosure of information under subsection (a)(2), the risk to national security due to the disclosure of such information outweighs the risk due to not disclosing such information; and (3) providing a classified or unclassified notice of the determination made under paragraph (2) not later than 30 days after making that determination to the Federal Acquisition Security Council that includes— (A) a summary of the information required for the purchase of property or services under this title and any other applicable law relating to procurement; and (B) a summary of the basis for the determination, including a discussion of less intrusive measures that were considered and why such measures were not reasonably available to reduce supply chain risk. (c) Limitation on disclosure If the head of an executive agency has exercised the authority provided in subsection (a)(2) to limit disclosure of information— (1) no procurement action undertaken by the head of the agency under such authority shall be subject to review in a bid protest before the Government Accountability Office or in any Federal court
