Chapter 9, Title 11, United States Code is a chapter of the United States Bankruptcy Code, available exclusively to municipalities, that assists them in the restructuring of debts. On July 18, 2013, Detroit, Michigan became the largest city in the history of the United States to file for Chapter 9 Bankruptcy protection. Jefferson County, Alabama, in 2011 and Orange County, California, in 1994 are also notable examples. "The term 'municipality' means political subdivision or public agency or instrumentality of a State."
