In France there are a lot of new laws every year (~100) but at least on third of them will not be enforced, mostly because there is no budget to implement them, or it is political gesticulation to please some electors [0].

For example over the year 2009/2010, 59 laws, which provided for 670 implementing decrees, were promulgated.

According to a Senate report, as of September 30, 2010, only 3 laws had received all of their implementing decrees. And only 20% of these decrees had seen the light of day. However, a law without an implementing decree is useless: it is not applicable.
