The Constitution of the United States of America: Analysis and Interpretation (popularly known as the Constitution Annotated) contains legal analysis and interpretation of the United States Constitution, based primarily on Supreme Court case law. This regularly updated resource is especially useful when researching the constitutional implications of a specific issue or topic. The Featured Topics and Cases page highlights recent U.S. Supreme Court decisions that demonstrate pivotal interpretations of the Constitution's provisions.

The Constitution comprises the primary law of the United States. It describes the three chief branches of the Federal Government and their jurisdictions, and lays out the basic rights of the country's citizens. The world's longest surviving government charter, the Constitution was framed in May 1787 by a convention of delegates from twelve of the thirteen original states in Philadelphia.

The Constitution Annotated provides a clause-by-clause explanation of this landmark document, with references to nearly 8,000 Supreme Court cases. Constitutional law experts from the Congressional Research Service author the treatise and the Government Printing Office publishes the editions and supplements.

The 2013 Centennial Edition of the Constitution Annotated

The centennial edition of the treatise was published by the Government Printing Office (GPO) in 2013, along with a web version. Publications were formerly limited to hard-bound decennial editions and separate soft-cover biannual supplements, but the online resource allows for the publication of up-to-date PDF versions of the treatise throughout each Supreme Court term. Both full-text searches and browsing by subject or case are available through the GPO FDsys website.
