“. . . the Conventions shall have the force of law in the United Kingdom.” [11] By s 1 of the Act it is provided that the term “Conventions” in the Act refers to a series of international conventions, including the Rome Convention. As the judge observed, certain provisions of the Rome Convention were excluded from the incorporation of its terms into English law, but these are not relevant for present purposes. Section 3(3) of the Act provides: “Without prejudice to any practice of the courts as to the matters which may be considered apart from this subsection – (a). the report on the Rome Convention by Professor Mario Giuliano and Professor Paul Lagarde which is reproduced in the Official Journal of the Communities of31st October 1980 may be considered in ascertaining the meaning or effect of any provision of that Convention; . . .”
“In the interpretation and application of the preceding uniform rules, regard shall be had to their international character and to the desirability of achieving uniformity in their interpretation and application.” [14] In Samcrete Egypt v Land Rover Exports Ltd[2001] EWCA Civ 2019 , Potter LJ (with whom Thorpe LJ agreed) quoted art 18 in para 24 of his judgment and observed, in para 25, that it was suggested at para 32-078 (p 1223) of the 13th edition of Dicey & Morris on the Conflict of Laws: “. . . that the question of interpretation should be looked at from a broad Convention-based approach, not constrained by national rules of construction.” [15] He expressed his agreement and, in para 26, approved my own view expressed in Egon Oldendorff v Libera Corp[1996] 1 Lloyd's Rep 380 at 387, where I said: “It is indeed appropriate to adopt a purposive approach and not to construe the Convention in a narrow literal way.”
“ ... the demonstration of the parties’ choice of law, by reference to subsequent conduct, is to be characterised not as a rule of evidence but as part of the freedom conferred by Article 3(1) to demonstrate the chosen law by all the circumstances of the case. Where the parties’ post-contractual conduct gives a reasonable indication of their actual intention at the time of the conclusion of their agreement, there is no good reason for excluding it.”
“The court is not precluded from taking into account any particular type of factor when applying Article 4(5) and is not required to look at the contract in question in isolation from other contracts with which it is connected.”
