"Ex Parte Merryman"

May 4, 2017

In May, 1861, in the wake of the Pratt Street Riots, Chief Justice Roger B. Taney issued a writ of habeas corpus for John Merryman, who had been imprisoned at Fort McHenry for his actions preventing the movement of Federal troops into Maryland. The decision became known as "Ex Parte Merryman," and was upheld by the Supreme Court in 1866.
