Foreign and Comparative Law Research Guide

Foreign law is the national (also referred to as domestic or internal) law of any country other than the United States and research methods will vary depending on the country you are researching. This guide provides starting points.

Foreign Constitutions

For most foreign jurisdictions, constitutional texts are relatively easy to locate and are often available in English translation.  Listed below are the best electronic resources and print resources for researching current and/or historical constitutions from jurisdictions around the world. 

Bear in mind that a handful of jurisdictions, most notably the United Kingdom, do not have written constitutions.  It's also worth noting that some foreign jurisdictions amend their constitutions much more frequently than the United States does, in part because the constitutional amendment process is less onerous.
