What are the main statutory exceptions to the Posse Comitatus Act?
There are many statutory exceptions to the Posse Comitatus Act, but the most important one is the
Insurrection Act. Under this law, in response to a state government’s request, the president may deploy the military to suppress an insurrection in that state. In addition, the Insurrection Act allows the president — with or without the state government’s consent — to use the military to enforce federal law or suppress a rebellion against federal authority in a state, or to protect a group of people’s civil rights when the state government is unable or unwilling to do so.
The law generally prevents the president from using the military as a domestic police force.
