(1878)
prohibited use of the U.S. Army to aid civil officials in enforcing the law or suppressing civil disorder unless expressly ordered to do so by the president. Southern Democratic members of the House who resented widespread use of federal troops during Reconstruction introduced the law. Some northern congressmen supported the law due to the army's role in suppressing disorders during the 1877 railroad strike.
In the past, soldiers had occasionally served as posses to assist U.S. marshals or judges without reference to the president. During the 1850s, U.S. Attorney General Caleb Cushing ruled that U.S. marshals could call upon federal soldiers, Marines, and sailors to help enforce the Fugitive Slave Act in the North. Such troops performed similar duties when called on by territorial governors in Kansas and Utah. Regulars routinely acted as posses during Reconstruction in the South, particularly during election disorders. Troops suppressing the 1877 railroad riots took orders from state governors and even municipal officers.
Use of federal troops as a posse comitatus placed them outside the military chain of command and the commander in chief's direct authority. Too often the practice turned regulars into policemen serving the interests of locals directly involved in the disputes provoking disorder. Army officers welcomed the Posse Comitatus Act and the new regulations it engendered, for they felt more comfortable performing their duty safely within the chain of command. The provisions of the act have governed army regulations and civil disorder doctrine to the present.
