An advisory opinion of a court or other government authority, such as an election commission, is a decision or opinion of the body but which is non-binding in law and does not have the effect of adjudicating a specific legal case, but which merely legally advises on its opinion as to the constitutionality or interpretation of a law. The International Law Association is one such commission that provides non binding opinions and advisory documents regarding aspects of international law. Some countries have procedures by which the executive or legislative branches may refer questions to the judiciary for an advisory opinion. In other countries or specific jurisdictions, courts may be prohibited from issuing advisory opinions.
