71 Essential background information

There is a further way in which the CFR would be valuable as a legislators' guide, and it has been prepared with a view to that possible purpose. If EU legislation is to fit harmoniously with the laws of the Member States, and in particular if it is neither to leave unintended gaps nor to be more invasive than is necessary, the legislator needs to have accurate information about the different laws in the various Member States. The national notes to be included in the full version of the DCFR will be very useful in this respect. They would, of course, have to be frequently updated if this purpose is to be served on a continuing basis.
