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.
