The CISG Advisory Council Opinions are drafted by rapporteurs appointed by the Council.

The Draft Opinions are discussed and a final text for the Black Letter Rules decided at the Advisory Council meetings.

The Comments are circulated and adopted after further discussion.

The Rules and Comments are primarily designed to assist courts and arbitrators with the uniform interpretation of the CISG when dealing  cases under the CISG. The Comments are there to serve the Rules and not to provide an extensive comparative treatment of the subject that is being dealt with.

Opinions and Declarations in Alternative Languages

The CISG Advisory Council is committed towards the translation of the black letter texts of the various opinions not only into the five other official languages of the CISG, but also a number of other important trading languages like Japanese and German. This project is currently not yet complete, but the various translations will be added as they become available.
