Foreign-property litigation can bar later Scottish damages claims where the same alleged agreement is the “foundation” of both cases (res judicata by substance, not remedy)

1) Introduction

Case: Balraj Singh Binning v Davindar Binning (Outer House, Court of Session), [2026] CSOH 33
Judge: Lady Tait
Date: 31 March 2026

The pursuer, Balraj Singh Binning, sued as executor of his late father Parmjit Singh Binning (“the deceased”). The defender, Davindar Binning, is the deceased’s brother.

The Scottish action sought £615,051 said to arise from (i) breach of contract and (ii) fraudulent misrepresentation. The alleged contract was a three-part family arrangement said to have been agreed orally in March 2005 and partly recorded in a written “Memorandum of Family Arrangement” dated 17 May 2005: the deceased would (a) pay sums towards the defender’s tax/professional liabilities and (b) procure transfer of a Scottish property to the defender, in exchange for (c) the defender transferring an Indian property in Chandigarh to the deceased. The pursuer maintained the “three legs” were “mutually dependent”.

The defender denied any agreement and pled res judicata based on prior Indian litigation. In India, the deceased had sued (from 2006) for a declarator and injunction asserting ownership/possession of the Indian property on the basis of the same alleged family arrangement; that suit was dismissed on 23 December 2022 (“the 2022 Indian judgment”) and an appeal was dismissed on 27 November 2025 (“the 2025 appellate judgment”).

The Scottish preliminary proof was concerned solely with whether the defender’s plea of res judicata barred the Scottish action. (A plea of forum non conveniens was not insisted upon.)

2) Summary of the Judgment

Lady Tait sustained the defender’s plea of res judicata and granted decree of absolvitor (dismissal on the merits), reserving expenses.

Although the Indian proceedings sought property-focused remedies (declarator/injunction) and the Scottish proceedings sought damages, the court held that Scots res judicata depends on the “substance and reality” of what was litigated and decided. On a plain reading of the Indian judgments, the alleged March 2005 oral arrangement (and the May 2005 writing) was pled, disputed, litigated, and rejected in India. The same alleged agreement was the central foundation of the Scottish damages and misrepresentation claims. Accordingly, the subject matter and the media concludendi were substantially the same, and the action was barred.

3) Analysis

3.1 Precedents Cited

Primary Health Care Centres (Broadford) Ltd v Ravangave [2009] CSOH 46, 2009 SLT 673

This case supplied the structured test for res judicata applied by Lady Tait (and later adopted in the Inner House). Lord Hodge’s five requirements—competent prior court; decree in foro contentioso without fraud/collusion; same subject matter; same media concludendi; and same parties (or representatives/same interest)—framed the Scottish court’s enquiry. Lady Tait treated (i), (ii), and (v) as undisputed and focused analysis on (iii) and (iv).

Smith v Sabre Insurance Co Ltd [2013] CSIH 28, 2013 SC 569

Cited as Inner House endorsement of Lord Hodge’s summary in Primary Health Care Centres (Broadford) Ltd. Its role was confirmatory: the governing Scots principles were settled and required a substance-based comparison of the two litigations.

Glasgow & South Western Railway Company v Boyd & Forrest (No 4) 1918 SC (HL) 14

This House of Lords authority provided the authoritative definition of medium concludendi—not a mere plea in law, but “the reality and substance of the thing disputed between the parties.” Lady Tait used this to reject the pursuer’s attempt to distinguish the cases by focusing on the formal remedies sought (property declarator/injunction versus damages) rather than the core disputed foundation (existence/enforceability of the alleged family agreement).

Carew-Reid v Lloyds Banking Group plc and Lloyds TSB Bank plc [2013] CSOH 5

This authority supported two points critical to cross-border litigation: (a) the prior tribunal can be foreign and still found a Scots res judicata plea; and (b) the court asks “what was litigated and what was decided?” rather than adopting technical comparisons of pleadings. It also confirmed that a possibility of appeal does not prevent res judicata—a point Lady Tait reinforced when treating the Indian determination as final on the merits notwithstanding theoretical further appeal routes.

Hamilton v Dutch East India Company (1732) 3 ER 573

Cited for the proposition that the competent tribunal founding res judicata can be of “equal, inferior or superior jurisdiction,” underpinning the general acceptance that foreign adjudications may have preclusive effect in Scotland where the res judicata requirements are met.

Durkin v HSBC Bank PLC [2016] CSIH 93, 2017 SLT 125

The Inner House reaffirmed the public policy basis of res judicata: preventing repeated litigation “on substantially the same basis,” and the need to focus on the “essence and reality of the matter.” Lady Tait relied on this policy rationale expressly when concluding that the pursuer’s damages action was, in substance, an attempt to re-litigate the same foundational issue already decided in India.

Grahame v Secretary of State for Scotland

Although not analysed independently in the Opinion, it was invoked through Durkin as authority for the public-policy and “essence and reality” approach. Its functional contribution was to reinforce that Scots courts do not decide whether the first tribunal was “right or wrong”; the point is finality.

McCluskey v Scott Wilson Scotland Ltd [2024] CSIH 26, 2025 SC 15

This recent Inner House authority sharpened the practical test into two questions: (1) same parties? and (2) does the issue proceed on substantially the same basis? It also emphasised that adding detail does not change the “essence” of what was litigated. Lady Tait applied that logic in treating additional averments (such as further payments) and different remedies as insufficient to avoid preclusion where the alleged agreement remained the hinge of liability.

3.2 Legal Reasoning

(a) Uncontested res judicata elements

  • Competent jurisdiction: The 2022 Indian judgment was a determination by a competent court.
  • Foro contentioso: It was pronounced in contested proceedings without fraud or collusion (as a procedural taint of the judgment itself).
  • Same parties/representatives: The executor was eadem persona cum defuncto, pursuing the deceased’s interest; the defender was the same. Lady Tait also noted the executor had pursued the Indian appeal.
  • Finality: The Indian judgment was treated as final on the merits; theoretical further appeals did not prevent res judicata.

(b) The contested elements: same subject matter and same media concludendi

The pursuer’s core distinction was remedial: India decided only property title/injunction based on the written family arrangement, while Scotland sought money based on an oral agreement (with fraudulent misrepresentation pled separately). The pursuer’s expert framed the Indian case as “property-centric” and suggested the oral agreement was not directly and substantially in issue.

Lady Tait rejected that characterisation as inconsistent with the Indian judgments “on any plain reading.” Key steps:

  • The oral March 2005 agreement was pled, denied, and determined in India: the Indian judgment narrated the pleaded oral settlement (March 2005) and treated “the factum of alleged oral family settlement and the document” as “completely denied” and as the “very foundation” of the plaintiff’s case. Lady Tait held that it was therefore “litigated before and decided by the Indian courts.”
  • The written memorandum was not separable from the alleged oral agreement: the Indian court analysed the “nature and purpose” of the document and the surrounding circumstances, which necessarily engaged with the alleged oral bargain said to underpin it.
  • Different conclusions do not prevent res judicata where the foundation is the same: the Scottish court looked past the difference between (i) declarator/injunction and (ii) damages, and asked whether the same “ground of action” (in substance) was being re-advanced. Lady Tait held it was: both actions rested on the existence and enforceability of a 2005 family agreement requiring transfer of the Indian property, which India had rejected.
  • Additional factual detail (payments/Scottish transfer) did not change the “essence”: the damages claim relied on the same agreement as the juridical basis for saying the deceased’s payments and the Scottish transfer were referable to a reciprocal obligation to convey the Indian property. Since India had rejected that arrangement, the additional detail could not avoid preclusion.
  • Fraudulent misrepresentation claim rose and fell with the agreement: the misrepresentation case depended on the defender having represented he would perform the same alleged agreement. If the agreement itself had already been adjudicated as not proved (and the written arrangement found fraudulent in the Indian proceedings), the Scottish misrepresentation case was not a distinct medium concludendi.

(c) Treatment of expert evidence

The pursuer’s expert attempted to confine the Indian adjudication to “property-centric” relief and to treat the oral agreement as merely “evidential.” Under cross-examination, she accepted that the Indian court made findings that the plaintiff’s case (including the oral agreement narrative) was not proved and accepted that the court’s analysis required consideration of the oral agreement.

The defender’s expert emphasised that the oral agreement and its written record were directly and substantially in issue. Lady Tait’s conclusion ultimately rested less on expert characterisation and more on the Scottish court’s own reading of the Indian judgments, which she treated as plainly demonstrating that the agreement’s existence was central and decided.

3.3 Impact

  • Cross-border preclusion beyond remedy labels: The decision reinforces that a foreign judgment can bar later Scottish litigation even where the later action is framed as damages (or misrepresentation) rather than property relief, if both depend on the same alleged underlying agreement.
  • Limits on “re-packaging” after failure abroad: Parties cannot avoid preclusion by recasting an unsuccessful foreign property claim into a Scottish monetary claim if the foreign court’s rejection goes to the existence/enforceability of the alleged bargain said to justify both.
  • Practical pleading strategy in multi-forum disputes: Litigants must consider that choosing to litigate the existence of an agreement in one forum (even incidentally to property remedies) may foreclose subsequent claims elsewhere that require that agreement as their juridical foundation.
  • Executor standing and finality: The Opinion confirms the ease with which res judicata may apply against successors/representatives (eadem persona cum defuncto), and reiterates that theoretical further appeals do not necessarily prevent a Scottish court treating the foreign judgment as final for preclusion purposes.

4) Complex Concepts Simplified

  • Res judicata: A rule preventing the same parties (or their representatives) from litigating again issues already finally decided by a competent court.
  • In foro contentioso: The earlier decision was made in contested proceedings (not by consent or default in a way that undermines its contested character), and is not tainted by fraud/collusion in the process producing the judgment.
  • Subject matter: Not the formal remedies claimed, but what the dispute is really about in substance.
  • Medium concludendi / media concludendi: The real basis on which a party says they are entitled to win—the essential factual/legal foundation of the claim, not the wording of pleas-in-law.
  • Eadem persona cum defuncto: An executor suing for a deceased person’s estate is treated as representing the same legal interest as the deceased for these purposes.
  • Decree of absolvitor: A decree dismissing the action on its merits (as opposed to a dismissal on procedural grounds), typically preventing re-litigation.
  • Forum non conveniens: A plea that another forum is more appropriate for the dispute; here it was pled but not pursued.

5) Conclusion

Lady Tait’s Opinion applies orthodox Scots res judicata principles to a modern cross-border family/property dispute and clarifies their practical bite: where a foreign court has already determined that an alleged underlying agreement was not proved (or was fraudulent), a later Scottish action seeking different remedies will be barred if it depends on that same agreement as its “foundation.” The decision underscores the Scottish courts’ consistent emphasis—drawn from Primary Health Care Centres (Broadford) Ltd, Glasgow & South Western Railway Company, Durkin and McCluskey—on substance over form: the question is not how a new action is labelled, but “what was litigated and what was decided?”
