Article 5 — Interpretation and applicable law

1. In the interpretation of this Convention, regard is to be had to its purposes as set forth in the preamble, to its international character and to the need to promote uniformity and predictability in its application.
2. Questions concerning matters governed by this Convention which are not expressly settled in it are to be settled in conformity with the general principles on which it is based or, in the absence of such principles, in conformity with the applicable law.
3. References to the applicable law are to the domestic rules of the law applicable by virtue of the rules of private international law of the forum State.
4. Where a State comprises several territorial units, each of which has its own rules of law in respect of the matter to be decided, and where there is no indication of the relevant territorial unit, the law of that State decides which is the territorial unit whose rules shall govern. In the absence of any such rule, the law of the territorial unit with which the case is most closely connected shall apply.
