Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
District of Columbia home rule
The District's local justice system is centered on the Superior Court of the District of Columbia, which hears all local civil and criminal cases, and the District of Columbia Court of Appeals, which serves as the highest local appeals court in District of Columbia. Despite the fact that the local courts are technically the third branch of the D.C. government, they are funded and operated by the United States federal government. Though operated by the federal government, the District's local courts are separate from the United States District Court for the District of Columbia and the United States Court of Appeals for the District of Columbia Circuit, which only hear cases regarding federal law.
