On 30 March, the Constitutional Council, the highest constitutional authority, validated most of the law, along with its 8th article instituting the First Employment Contract. The law was considered to abide by the Constitution of France; the Constitutional Council didn't pronounce on the question of conformity to international and European law, which it is not empowered to consider. The Socialist deputies and senators who had deposed the legal recourse before the Constitutional Council notably claimed that the law was superseded by article 24 of the European social charter, which states that the employer must give a juridical motive before firing an employee, and against the International Labour Convention (n°158). Labor courts would have to create jurisprudence concerning this point.
