The idea of a European minimum wage, resuscitated by certain candidates during the election campaign, is not just a Franco-French one, points out French magazine L’Express. Many MEPs, notably Greek ones, have already petitioned the Commission on the issue. The right-wing weekly points out that legal obstacles to the adoption of a Europe-wide minimum wage are still numerous. "Article 137 of the Treaty of Rome expressly precludes the European community from having anything to do with salaries of European citizens," says Dominique Aguilar PhD, a specialist in public and European law recently interviewed by the magazine. Also, ratifying a guaranteed minimum wage would be a long and arduous process, which would require a revision to the treaty. The European Council, made up national heads of states would have to call an intergovernmental conference and approve the project unanimously. L’Express reminds readers that not all members states, however, agree on the principle of a minimum wage.
