EU institutions have always sought input by national administrations, businesses and civil society groups - or lobbyists - to assist them shaping or implementing policies. The practice became compulsory in 1997 with the Amsterdam Treaty requiring the Commission to consult widely and publish documents before putting forward major new pieces of legislation. This led to the adoption of basic principles for public consultation to ensure all relevant interested parties are properly heard. Three years on, the Commission wants to take the process to the next level by making public consultations a full aspect of EU lawmaking. In doing this, the Commission hopes to bolster the EU's transparency and legitimacy and regain public trust in the European project.
