  Current Statutes

  Michigan has one unofficial online codified database, one official codification in print and two unofficial commercial codifications of its laws. Bluebook Rule T1 (p. 264 in 21st ed.) allows for citation to the commercial codifications MCLA and MCLS.

  Superseded Statutes

  Public and Local Acts of the Legislature of the State of Michigan (session laws)(1835~)

  • Michigan’s session laws are published in Public and Local Acts of the Legislature of the State of Michigan.

  • Historical and statutory notes sections, when available, give additional details such as which parts of the act were amended by which amendments.

  Repealed Statutes
