Respondents estopped from challenging compromise deed based on arbitral award; Section 92 CPC bars voidness challenge

SC allowed the appeal and set aside the impugned order, holding that respondents are estopped from challenging a compromise deed founded on an arbitral award after they had accepted it and procured disposal of their appeal on that basis. The Court found the respondents' prior pleadings asserted the suit was maintainable and they voluntarily sought settlement; they cannot now contend the award or resulting decree is void under Section 92 CPC. Justice required permitting the appellants to revive execution proceedings restraining interference with the Trust's school; appeal allowed.

1. ISSUES PRESENTED AND CONSIDERED

1. Whether a party may invoke estoppel by conduct or election to bar the other party from challenging the validity or arbitrability of an arbitral award (and a consent/compromise decree founded on it) when that party previously accepted the award and procured disposal of litigation in terms thereof.

2. Whether an arbitral award that deals with matters alleged to be non-arbitrable under Section 92 of the Civil Procedure Code can be treated as a nullity for all purposes, including enforcement, notwithstanding the parties' subsequent acceptance and incorporation of the award into a court decree.

3. Whether the plea that "there can be no estoppel against law" or that invalidity of an award can be urged at any stage defeats estoppel by conduct/election where the opposing party altered its position to its detriment in reliance on the award/consent decree.

4. Whether, in the circumstances where a consent/compromise decree arising from an award has not been challenged, relief by way of execution should be permitted to proceed despite later judicial findings of non-arbitrability in separate proceedings.

2. ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Permissibility of raising estoppel when party previously accepted award/consent decree

Legal framework: Doctrine of estoppel by conduct/election and the equitable principle prohibiting approbation and reprobation (qui approbat non reprobat). A party who accepts benefits under an instrument or manifests an unequivocal choice is ordinarily precluded from later adopting an inconsistent position to the detriment of the other.

Precedent Treatment: The Court relied on established jurisprudence recognizing the doctrine of election/estoppel and the principle that a litigant cannot assume inconsistent positions over the same transaction; prior authorities applying these equitable maxims were followed as directly applicable.

Interpretation and reasoning: The Court found that the respondent-side initially pleaded that their suit was not barred by Section 92, sought adjudication on merits, and then jointly accepted an arbitral award and sought disposal of their appeal in terms of that award. Having so acted, the respondents induced the appellants to alter their position (withdrawal of FIR, payment of sums, compliance steps) in reliance on the award/compromise. The conduct constituted an unequivocal election to accept the award and procure a decree; to allow retraction of that position would permit approbation and reprobation.

Ratio vs. Obiter: Ratio - where a party has accepted an award and procured a consent/compromise decree, that party is estopped from subsequently denying the award's validity or arbitrability to the detriment of the accepting party who acted in reliance.

Conclusion: The Court held that estoppel by conduct/election barred the respondents from taking an opposite stand; they could not now be permitted to repudiate the award/consent decree they had accepted and relied upon.

Issue 2 - Effect of alleged non-arbitrability (Section 92) on enforceability of award/consent decree accepted by parties

Legal framework: Distinction between substantive illegality/invalidity of an award and equitable estoppel; the competency of courts to examine arbitrability under statutory provisions; and the finality of consent decrees unless challenged within proper avenues.

Precedent Treatment: The Court acknowledged authorities holding that awards beyond jurisdiction or dealing with non-arbitrable matters may be treated as nullities, but held that such principles operate subject to equitable considerations where parties have acted on the award and obtained an unchallenged decree - earlier rulings on estoppel and acceptance of awards were applied.

Interpretation and reasoning: Although Section 92 may render certain trust-affairs non-arbitrable, the Court emphasized that the respondents' active choice to have disputes resolved by arbitration and to accept the award (leading to a decree) estopped them from subsequently asserting the award's nullity. The Court treated the issue as primarily one of estoppel by conduct rather than purely a question of arbitrability. It found that the equitable consequences of the parties' conduct (detrimental reliance by appellants) outweighed the respondents' later assertion of non-arbitrability in separate proceedings.

Ratio vs. Obiter: Ratio - where parties accept an award and secure a consent/compromise decree which is not challenged, the ensuing decree cannot be impugned by one party on arbitrability grounds when the other has altered position to its detriment in reliance on that decree; courts need not decide the legality of the award once estoppel by conduct applies.

Conclusion: The Court held that the question of arbitrability, though significant, did not permit the respondents to escape the consequences of their prior acceptance; the award/consent decree could not be treated as a nullity vis-à-vis the appellants on the facts before the Court.

Issue 3 - "No estoppel against law" argument and timing of raising invalidity

Legal framework: Principle that an illegality cannot be validated by estoppel is acknowledged; however, equitable estoppel may preclude a party from asserting legal invalidity where the party's own conduct induced detrimental reliance by the other. The elements of estoppel require representation (or conduct), reliance, and detriment.

Precedent Treatment: The Court distinguished authorities asserting "no estoppel against law" by underscoring situations where the representation asserted was of existing facts (not merely a promise) and where acceptance induced change of position; prior decisions recognizing estoppel even where legal questions underlay the award were followed.

Interpretation and reasoning: The Court accepted that an award beyond jurisdiction can be impugned, but explained that such objections cannot be used to defeat equitable expectations created by a party's own conduct in accepting and acting upon the award. Citing past rulings, the Court observed that even issues of title or law can be estopped where the party's conduct represented facts which induced the other to act to its detriment.

Ratio vs. Obiter: Ratio - the maxim that "there can be no estoppel against law" does not automatically render estoppel inapplicable where a party previously accepted and acted upon an award; estoppel by conduct can preclude asserting invalidity in appropriate circumstances.

Conclusion: The respondents could not rely on the "no estoppel against law" principle to overturn their prior acceptance and the resulting detriment to the appellants.

Issue 4 - Remedy: revival of execution proceedings and scope of relief when consent decree unchallenged

Legal framework: Execution of consent decrees is a recognized remedy; where a consent/compromise decree has been passed and not challenged, an aggrieved party who acted in reliance may seek execution unless equitable bars apply. Courts may grant relief to prevent parties from benefitting from prior approbation and subsequent reprobation.

Precedent Treatment: The Court applied equitable remedies from prior jurisprudence permitting enforcement of decrees and recognizing that parties should not be left remediless when they altered position in reliance on an unchallenged decree.

Interpretation and reasoning: Because the consent/compromise decree was not challenged, the appellants had validly filed execution proceedings (later withdrawn only to invoke Section 9 remedies). Denying the appellants all remedy by treating the award as a nullity in separate proceedings produced grave injustice and would reward inconsistent conduct by the respondents. The Court therefore restored the appellants' ability to pursue execution so that the decree may be adjudicated on merits.

Ratio vs. Obiter: Ratio - where a consent/compromise decree has been procured by mutual acceptance of an award and remains unchallenged, the party who acted in reliance should be permitted to revive execution proceedings and have the decree adjudicated on its merits when the opposing party seeks to repudiate the award.

Conclusion: The Court set aside the impugned orders denying relief and allowed revival of the execution proceedings; the execution must be decided on merits and in accordance with law, preventing respondents from reaping advantage from approbation and reprobation.

Cross-reference: Issues 1-3 are interlinked; the Court declined to adjudicate the substantive legality of the award (arbitrability under Section 92) because estoppel by conduct and election (Issue 1) furnished a standalone equitable bar to the respondents' later challenge (Issue 2 & 3), thereby guiding the remedial conclusion on Issue 4.
