Substituted settlement and arbitration clauses: Supreme Court reasoning on when earlier contractual rights and arbitration survive.

A complete substituted settlement that finally concludes earlier contracts extinguishes the prior rights and liabilities and replaces them with the new arrangement. On that footing, an arbitration clause embedded in the earlier contracts does not survive unless the settlement expressly or by necessary implication preserves it, because the clause has no independent existence apart from the contract containing it. The majority view treated the settlement as novation and upheld the award; the dissent characterised it as mere accord and satisfaction, saying the arbitration clause survived.

Issues: (i) whether the settlement of 22 February 1949 superseded the earlier contracts and extinguished the rights and liabilities arising under them; (ii) whether the arbitration clause in the earlier contracts survived after the settlement and could sustain the reference to arbitration.

Issue (i): Whether the settlement of 22 February 1949 superseded the earlier contracts and extinguished the rights and liabilities arising under them.

Analysis: The settlement was a complete and self-contained arrangement dealing with the outstanding mutual claims, fixing the amount payable, providing the mode of payment, and stating that the contracts stood finally concluded in terms of the settlement. The language and structure of the settlement showed an intention to substitute the earlier arrangements and regulate the parties' rights thereafter only under the new settlement. The earlier contracts were therefore not left operative as independent sources of rights and liabilities.

Conclusion: The settlement superseded the earlier contracts and displaced the rights and liabilities under them.

Issue (ii): Whether the arbitration clause in the earlier contracts survived after the settlement and could sustain the reference to arbitration.

Analysis: An arbitration clause is an integral part of the contract in which it is embedded and has no existence apart from that contract. Where the original contract is wholly substituted by a new agreement, the arbitration clause in the earlier contract falls with it. The disputes in question arose under the settled and superseded contracts, not under a surviving arbitration agreement. The arbitration clause could not, therefore, be invoked to found jurisdiction for the award.

Conclusion: The arbitration clause did not survive the settlement and could not sustain the arbitration.

Final Conclusion: The award was upheld because the earlier contracts, and with them the arbitration clause, had been extinguished by the substituted settlement; the application to set aside the award therefore failed.

Ratio Decidendi: Where parties enter into a complete substituted settlement that is intended to conclude the original contracts, the earlier contracts are extinguished and an arbitration clause contained in them perishes with them unless the new arrangement expressly or by necessary implication preserves it.

Dissenting Opinion: Sarkar, J. held that the settlement was only an accord and satisfaction dealing with remedies for breach, not a novation destroying the earlier contract or its arbitration clause. On that view, the arbitration agreement survived and the award was not a nullity.
