Good quality of legislation is one of the main concerns of the European Union. Given that the EU system is not a single structure but coexists with the legislative systems of the Member States, there is a need to have a Community legislation system which is adaptable to the particular conditions of its Member States and which contributes to the consolidation of the Internal Market. With the purpose of achieving this goal in a sustainable way, in 2011 the European Commission issued its White Paper on European Governance. It stated the necessity of a better and simpler regulatory system involving the participations of all the relevant actors -central governments, regions, cities and civil society. It also declared that ""to improve the quality of its policies, the Union must first asses whether action is needed and, if it is, whether it should be at Union level. Where Union action is required, it should consider the combination of different policy tools. When legislatin, the Union needs to find ways of speeding up the legislative process. It must find the right mix between imposing a uniform approach when and where it is needed and allowing greater flexibility in the way that rules are implemented on the ground. It must boost confidence in the way expert advice influences policy decisions.
