Abstract EN:

The transitional provisions show up in a law or a new regulation and determine the methods of its action through time. Being temporary, they also show a secondary characteristic since their object relagate them to come along with another rule, the " final provision". They offer an alternative to the doctrinal and jurisprudential rules that govern the conflict of laws in time. Both categories of transitional provisions -Those installing particular conflict rules on the one hand and those who take on a substantial character on the other hand - are the only rules that are in the same time temporary and secondary. The juridical regime of transitional dispositions largely follows that the final provision : it only adapts the latter to the transitional provisions' particularity. They are furthermore submitted to specific rules : the transitional principles that are suject to evolution under the influence of European law. On the other hand, they show a specific modality of extinction.
