The Convention on the Law Applicable to Contractual Obligations 1980, or the "Rome Convention", is a measure in private international law or conflict of laws which creates a common choice of law system in contracts within the European Union. The convention determines which law should be used, but does not harmonise the substance (the actual law). It was signed in Rome, Italy on 19 June 1980 and entered into force in 1991. It has now been replaced by the Rome I Regulation (593/2008) except for in Denmark, which has an opt-out from implementing regulations under the area of freedom, security and justice, and the Overseas countries and territories of European Union member states. In that respect, the convention is applicable in Aruba, the Caribbean Netherlands, Curaçao, Sint Maarten (Kingdom of the Netherlands), Faroer (Denmark), Saint-Pierre and Miquelon, Saint Barthélemy, French Polynesia, Wallis and Futuna and New Caledonia (France). The agreement and regulation were applied by the United Kingdom during its membership of the European Union, and following Brexit it still applies the regulation as part of its domestic law. Scope of the convention Under Article 1, the Convention's rules are to apply to all choice of law issues involving contractual obligations and, under Article 10, once selected, the lex causae will govern: (a) interpretation; (b) performance but, in relation to the manner of performance and the steps to be taken in the event of defective performance, regard shall be had to the lex loci solutionis, i.e. law of the place in which performance takes place; (c) within the limits of the powers conferred on the forum court by its procedural law, the consequences of breach, including the assessment of damages in so far as it is governed by rules of law; (d) the various ways of extinguishing obligations, and the limitation of actions; and (e) the consequences of nullity of the contract. Article 15 excludes the operation of renvoi. In addition, a number of issues with a separate characterisation are excluded, namely: the status or capacity of natural persons. Article 11 covers the situation where two persons physically present in the same state make a contract, and both parties have capacity under the lex loci contractus. One party cannot invoke incapacity under another law unless the other party was aware of this incapacity at the time the contract was made or was not aware of the incapacity as a result
