A claim based on a cheque, not as a negotiable instrument (titolo di credito) but as a promissory note (promessa di pagamento), qualifies as a claim on matters relating to a contract for the purposes of Article 5(1) of Regulation (EC) No44/ 2001. In relation to said claim, the place of performance of the obligation in question within the meaning of the aforesaid provision shall be determined on the basis of the law governing said obligation pursuant to the conflict of law rules of the court seised.
