This document forms part of the ‘Compilation of Constitutional and Legislative Provisions on Treaty Practice of Selected States and International Organisations’, which contains the most important constitutional, legislative and other official provisions relevant to treaty practice of a selection of states and international organisations. The compilation was produced by the British Institute of International and Comparative Law (BIICL) and the Centre for International Law (CIL) as a handbook of reference material for participants at the Workshop on Treaty Law and Practice held in Singapore on 16-19 January 2012, and has been subsequently updated and adapted for publication as an online resource. 

The document on each state includes provisions relating to all aspects of national treaty practice including negotiation, signature, parliamentary scrutiny, consent to be bound, implementation and status of treaties in domestic law. The provisions are arranged in (broadly) the following order:

• constitutional provisions
• statutory provisions
• regulations, orders or other kinds of secondary legislation
• other documentation that sets out official requirements, conventions or procedures, including internal practice manuals whether published or unpublished
• official online sources of treaty status information

The document on each international organisation includes provisions concerning its powers and responsibilities in relation to treaties, including depositary functions, registration, publication, negotiation, signature, scrutiny, consent to be bound, implementation and compliance.
