Does the United States Court of Federal Claims have jurisdiction over cases against the United States based on an implied contract with an executive department of the federal government?

QUESTION(S) PRESENTED The United States Court of Federal Claims has jurisdiction over a wide range of claims against the government including but not limited to, contract disputes. When more than $10,000 is claimed, the Court of Federal Claims possesses exclusive jurisdiction in these cases pursuant to the Tucker Act, 28 U.S.C § 1491. Under the “Little Tucker Act,” 28 U.S.C. § 1346, the district courts possess concurrent jurisdiction with the Court of Federal Claims to entertain any monetary claim against the United States for an amount not exceeding $10,000 “founded either upon the Constitution, or any Act of Congress, or any regulation of an executive department, or upon any express or implied contract with the United States, or for liquidated or unliquidated damages not sounding in tort.” Does the United States Court of Federal Claims have jurisdiction over cases against the United States based on an implied contract with an executive department of the federal government? Should the United States be held accountable when violating the Constitution and its own federal regulations?
