The correct answer is C (at the local state court level) because, under NCMA CMBOK principles, disputes between a prime contractor and its subcontractors are considered private contractual matters. These relationships are governed by commercial contract law, not by federal procurement law, even when the prime contract is with the government.

CMBOK emphasizes that subcontractors generally do not have privity of contract with the government, meaning they cannot bring claims directly against the government or pursue remedies through federal forums such as the U.S. Court of Federal Claims. Instead, disputes between prime contractors and subcontractors are resolved based on the terms of their subcontract agreement, typically under state law.

As a result, such disputes are usually handled in state courts or through alternative dispute resolution (ADR) mechanisms specified in the subcontract. These forums provide jurisdiction over private contractual disputes and allow enforcement of contract terms, damages, or other remedies.

Option A (small claims court) is too limited and only applies to minor disputes. Option B is incorrect because that court handles claims involving the federal government, not subcontractor relationships. Option D (local agency level) is incorrect because government agencies are not parties to subcontract disputes.

CMBOK highlights that understanding privity of contract and jurisdiction is critical in the post-award phase, ensuring proper dispute resolution pathways are followed.
