The Advisory Committee is made up of representatives of the Member States and chaired by a Commission representative. The Commission representative presents a draft of the measures to be taken, and the Committee gives its opinion on them within a time limit set by the Commission. The Commission is expected, though not obliged, to take the fullest possible account of the opinion; it informs the Committee of the action taken on its suggestions and proposed amendments. The advisory committee procedure applies chiefly to measures required for the implementation of Council instruments for the achievement of the single market.
