Supreme Court, order of 15 June 2026, N. 19979

An arbitration clause contained in a contract is not apt to confer upon the arbitrators cognisance of disputes relating to a subsequent agreement, including a non-novative settlement, whereby the original contract was terminated by consent and the relations between the parties were regulated differently without any reference to the original contract; the principle of autonomy of the arbitration clause limits its extension to claims of invalidity of the contract to which it is appended, precluding its operation in respect of relationships arising from subsequent and distinct agreements.
