assignee. In particular, it should not cover preliminary questions as regards a voluntary assignment or a contractual subrogation. The term should be strictly limited to the aspects which are directly relevant to the voluntary assignment or contractual subrogation in question.
(39) For the sake of legal certainty there should be a clear definition of habitual residence, in particular for companies and other bodies, corporate or unincorporated. Unlike Article 60(1) of Regulation (EC) No 44/2001, which establishes three criteria, the conflict-of-law rule should proceed on the basis of a single criterion; otherwise, the parties would be unable to foresee the law applicable to their situation.
(40) A situation where conflict-of-law rules are dispersed among several instruments and where there are differences between those rules should be avoided. This Regulation, however, should not exclude the possibility of inclusion of conflict-of-law rules relating to contractual obligations in provisions of Community law with regard to particular matters.
(41) Respect for international commitments entered into by the Member States means that this Regulation should not affect international conventions to which one or more Member States are parties at the time when this Regulation is adopted. To make the rules more accessible, the Commission should publish the list of the relevant conventions in the Official Journal of the European Union on the basis of information supplied by the Member States.
(42) The Commission will make a proposal to the European Parliament and to the Council concerning the procedures and conditions according to which Member States would be entitled
to negotiate and conclude, on their own behalf, agreements with third countries in individual and exceptional cases, concerning sectoral matters and containing provisions on the law applicable to contractual obligations.
(43) Since the objective of this Regulation cannot be sufficiently achieved by the Member States and can therefore, by reason of the scale and effects of this Regulation, be better achieved at Community level, the Community may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary to attain its objective.
(44) In accordance with Article 3 of the Protocol on the position of the United Kingdom and Ireland, annexed to the Treaty on European Union and to the Treaty establishing the European Community, Ireland has notified its wish to take part in the adoption and application of the present Regulation.
(45) In accordance with Articles 1 and 2 of the Protocol on the position of the United Kingdom and Ireland, annexed to the Treaty on European Union and to the Treaty establishing the European Community, and without prejudice to Article 4 of the said Protocol, the United Kingdom is not taking part in the adoption of this Regulation and is not bound by it or subject to its application.
(46) In accordance with Articles 1 and 2 of the Protocol on the position of Denmark, annexed to the Treaty on European Union and to the Treaty establishing the European Community, Denmark is not taking part in the adoption of this Regulation and is not bound by it or subject to its application,
