European Committees (formerly European Standing Committees) are appointed to consider European Union documents in detail and to report their findings back to the House of Commons. Not all EU documents come before a European Committee. The European Scrutiny Committee decides which documents require further consideration by a committee and which are purely technical measures. The European Union Select Committee in the House of Lords scrutinise EU documents and other EU related matters.
