Habeas Corpus Suspension Act (1863)
Since the end of the Civil War, historians have constantly reviewed Abraham Lincoln's suspension of the writ of habeas corpus. Habeas corpus is stated in Article 1, Section 9 of the constitution as follows: "the privilege of the writ of habeas corpus shall not be suspended, unless when in cases of rebellion and invasion the public safety may require it...", and is sometimes referred to in short as "the suspension clause."
