"The Committee on Petitions deals with the specific concerns of the citizens and, in this respect, as has been pointed out by Mrs Lambert - who I warmly congratulate on her report - the petitions presented to Parliament illustrate the problems of the citizens in relation to European administrations and also, in many cases, national administrations, at the same time highlighting the legislative vacuums which exist on both European and national levels."
La commission des pétitions s' occupe des préoccupations concrètes des citoyens et, en ce sens, comme le signale Mme Lambert - que je félicite sincèrement pour son rapport -, les pétitions présentées au Parlement illustrent les problèmes des citoyens face aux administrations européennes et souvent nationales tout en mettant l' accent sur les lacunes législatives existant au niveau européen et national.
