contractual regulation

One last point: the interoperability obligation must apply to contractual regulations too.

On top of a number of administrative difficulties, European entrepreneurs are too often faced with very diverse contractual regulations in force in the Member States.

In any case, as called for in the report, what is required is a relevant contractual regulation designed to provide a firm basis for a form of individual responsibility which is legally enforceable in serious cases.

I would briefly add that though we often discuss a range of problems during political debate, here we are dealing with the maintenance of a contractual regulation: the preparation of the Customs Union by the Association Council.
