It is assumed that the question refers to the role of national parliaments in the European Union which is the subject of Declaration 13 annexed to the Treaty on Europen Union.
The Treaty of Amsterdam contains a Protocol on the role of national parliaments in the European Union. With regard to the provision of information for national parliaments of member states, the Protocol provides, inter alia,:
(a) for the prompt forwarding of all Commission consultation documents — green and white papers and communications — to national parliaments of the member states.
(b) that Commission proposals for legislation are made available in good time, so that the Governments of each member state may ensure that its own national parliament receives them as appropriate.
(c) for a minimum six-week period between a legislative proposal being tabled and its being placed on a Council agenda for decision, except in cases of particular urgency.
With regard to the Conference of European Affairs Committees of national parliaments and the European Parliament (COSAC), the Protocol contains a number of provisions concerning its right to (a) make contributions it deems appropriate for the attention of the institutions of the European Union, (b) examine any legislative proposal in relation to the establishment of an area of freedom, security and justice which might have a direct bearing on the rights and freedoms of individuals, (c) address to the European Parliament, the Council and the Commission any contribution it deems appropriate on the legislative activities of the Union, notably in relation to the application of the principle of subsidiarity, the area of freedom, security and justice as well as questions regarding fundamental rights.
The Protocol makes clear that contributions made by COSAC do not bind national parliaments or prejudge their position.
The text of the Protocol is as follows:
PROTOCOL ON THE ROLE OF NATIONAL PARLIAMENTS IN THE EUROPEAN UNION THE HIGH CONTRACTING PARTIES,
RECALLING that scrutiny by individual national parliaments of their own government in relation to the activities of the Union is a matter for the particular constitutional organisation and practice of each Member State,
DESIRING, however, to encourage greater involvement of national parliaments in the activities of the European Union and to enhance their ability to express their views on matters which may be of particular interest to them,
