In the United States, bankruptcy is largely governed by federal law, commonly referred to as the "Bankruptcy Code" ("Code"). The United States Constitution (Article 1, Section 8, Clause 4) authorizes Congress to enact "uniform Laws on the subject of Bankruptcies throughout the United States". Congress has exercised this authority several times since 1801, including through adoption of the Bankruptcy Reform Act of 1978, as amended, codified in Title 11 of the United States Code and the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 (BAPCPA).
