"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.

Federal habeas corpus is a procedure under which a federal court may review the legality of an individual's incarceration. It is most often the stage of the criminal appellate process that follows direct appeal and any available state collateral review. The law in the area is an intricate weave of statute and case law. Current federal law operates under the premise that with rare exceptions prisoners challenging the legality of the procedures by which they were tried or sentenced get "one bite of the apple." Relief for state prisoners is only available if the state courts have ignored or rejected their valid claims, and there are strict time limits within which they may petition the federal courts for relief. Moreover, a prisoner relying upon a novel interpretation of law must succeed on direct appeal; federal habeas review may not be used to establish or claim the benefits of a "new rule." Expedited federal habeas procedures are available in the case of state death row inmates if the state has provided an approved level of appointed counsel. The Supreme Court has held that Congress enjoys considerable authority to limit, but not to extinguish, access to the writ.
