48 CFR §33.203

1. (a)Except as specified in paragraph (b) below, this part applies to any express or implied contract covered by the Federal Acquisition Regulation.
2. (b)This subpart does not apply to any contract with
   1. (1)A foreign government or agency of that government; or
   2. (2)an international organization or a subsidiary body of that organization, if the agency head determines that the application of the Disputes statute to the contract would not be in the public interest.
3. (c)This part applies to all disputes with respect to contracting officer decisions on matters “arising under” or “relating to” a contract. Agency Boards of Contract Appeals (BCAs) authorized under the Disputes statute continue to have all of the authority they possessed before the Disputes statute with respect to disputes arising under a contract, as well as authority to decide disputes relating to a contract. The clause at 52.233-1, Disputes, recognizes the “all disputes” authority established by the Disputes statute and states certain requirements and limitations of the Disputes statute for the guidance of contractors and contracting agencies. The clause is not intended to affect the rights and obligations of the parties as provided by the Disputes statute or to constrain the authority of the statutory agency BCAs in the handling and deciding of contractor appeals under the Disputes statute.
