Martial Law: Can Congress Impose It?

There is no clear answer to the question of whether Congress can declare martial law. The US Constitution does not explicitly define when a president can declare martial law, and Congress has not passed a law regarding when martial law can be declared. However, Congress did declare martial law during the Civil War, and some scholars believe that the Constitution's enumerated war powers give Congress the power to declare martial law. Others argue that the president has the executive power to declare martial law, while some believe that the president needs congressional authorization to impose martial law in a civilian area.

Congress may be the only governmental branch that can legally declare martial law

Congress itself declared martial law during the Civil War, but it has not passed a law regarding when martial law can be declared. The Constitution's enumerated war powers of the legislative and executive branches give both Congress and the president the power to declare martial law. However, the Constitution Annotated notes that martial law does not come from any direct authority, but instead "arises from the nature of things, being the law of paramount necessity". In other words, it comes from the government's right, power, and/or duty to "maintain public order" and keep the peace. During wartime, "supreme political authority" allows for the valid and constitutional use of martial law.

Were a president to declare martial law without cause, it's not clear what actions Congress or U.S. citizens could take, and would likely depend on the circumstances. However, Congress does always have the right to impeach a president for an abuse of power.
