(79)Such irrevocability should not affect a payment service provider’s rights or obligations under the laws of some Member States, based on the payer’s framework contract or national laws, regulations, administrative provisions or guidelines, to reimburse the payer with the amount of the executed payment transaction in the event of a dispute between the payer and the payee. Such reimbursement should be considered to be a new payment order. Except for those cases, legal disputes arising within the relationship underlying the payment order should be settled only between the payer and the payee.
