Constitutional Sheriffs and Peace Officers Association

The Constitutional Sheriffs and Peace Officers Association (CSPOA) is a political organization of local police officials in the United States who contend that federal and state government authorities are subordinate to the local authority of county sheriffs and police. Self-described constitutional sheriffs assert that they are the supreme legal authority with the power and duty to defy or disregard laws they regard as unconstitutional. As a result, they may sometimes be referred to as sovereign sheriffs. The movement is related to previous nullification and interposition notions, and promotes such efforts. It has been described as far-right by the Southern Poverty Law Center. The CSPOA has claimed a membership of 400.

According to the Associated Press, "details of its operations are closely held", and information on its finances, "where and how" it conducts its training, who its dues paying members are, have not been released to the public. The group is now a private company according to indications of "internal records".
