Consulting a research guide is a great first step when starting any international or foreign law research project.
When searching for the full text of a treaty, status information, preparatory works or other related treaty documents, search for the body or organization that promulgated the treaty. For example, the Council of Europe is a source of information for the European Convention on Human Rights and other Council of Europe treaties.
For additional guidance on researching the law of a foreign jurisdiction, see the foreign law research guides in the Research Guides section of this guide. For example, Introduction to Researching Foreign Law by GlobaLex.
