1. Issue estoppel prevents parties from continually litigating the same point. It is a particularly important feature in service charge disputes, where similar points are sometimes raised in multiple years.
2. The recent service charge case of Vernon v Orbit Housing Association[1] is the latest word on the matter. It follows a couple of important Upper Tribunal decisions, and the trio now serve as a useful examination of issue estoppel – both in s27A LTA 85 applications and in general litigation. It gives particularly importance guidance on when issue estoppel will not apply, even where the ingredients are otherwise made out.
FACTS OF VERNON v ORBIT
3. This was a s27A application. As practitioners will be aware, under such an application, the FTT may determine whether service charges are payable. This is subject to s19 LTA 85, which provides that the relevant costs which make up a service charge are only payable to the extent they are reasonably incurred. The jurisdiction only extends to variable service charges, as defined at s18 LTA 85.
4. In Vernon, the appellant was the assured tenant of a flat in a sheltered housing scheme, known as Rosalind Court. All tenancies, including the Appellant, required payment of:
- A Scheme Based Support Charge [“SBSC”]. The tenancy did not define what the SBSC was for; and
- Where applicable the costs associated with any separate bespoke support agreements [“Support Agreements”] for the provision of additional services.
It was uncontroversial that the Appellant did not benefit from a Support Agreement, and so was not required to pay anything under that part of the tenancy agreement.
5. The tenancy agreement also provided, of course, for payment of rent and a conventional variable service charge for repairs, maintenance etc.
6. The matter first came before the FTT in 2022. In these proceedings, the FTT was asked to determine whether the SBSC was payable in the service charge years 2021/22 and 2022/23. Amongst a range of findings, the FTT determined that:
- The SBSC in fact paid for the overnight care services provided to residents who benefitted from a Support Agreement (and so not the Appellant);
- Residents without a Support Agreement derived no benefit from the SBSC;
- As a matter of contractual construction, only residents with a Support Agreement were liable to pay the SBSC; and
- Alternatively, insofar as it related to the Appellant, the SBSC was not reasonable incurred, and so irrecoverable.
[“The First FTT Decision”]
7. The First FTT Decision was appealed to the Upper Tribunal[2]. The UT held that the SBSC was payable as a matter of contractual construction. However, the FTT had been entitled to conclude the SBSC was not reasonably incurred, on the evidence it had heard. As such, the SBSC was not payable for years 21/22 and 22/23[3] [“the First UT Decision”].
8. After writing off the SBSC for those years, the Respondent housing association began charging the Appellant for the SBSC again. This inevitably led to a second round of proceedings in respect of years 23/24 and 24/25. In this second set of proceedings, the Respondent provided far stronger evidence as to what the SBSC was paying for.
9. The Appellant maintained that nothing had been provided to him and that he did not wish to make use of any of the services provided.
10. The FTT found that the SBSC paid for services which benefitted the whole of Rosalind Court. It determined that the SBSC for the years in question was reasonably incurred [“the Second FTT Decision”].
11. The Appellant appealed the Second FTT Decision[4]. The basis was that the FTT was not entitled to make a decision that was inconsistent with the findings made in the First FTT Decision. The Appellant argued that it had been found that he derived no benefit from the SBSC, and that this finding was not limited to a particular period of time, but rather was a static fact. On that basis, it was contended that the finding applied to later service charge years unless further material – incapable of being adduced earlier with reasonable diligence – demonstrated that the earlier decision was wrong. In other words, that issue estoppel applied.
ISSUE ESTOPPEL
12. Issue estoppel is a type of res judicata. In Virgin Atlantic v Zodiac Seat UK[5], the Supreme Court identified a number of related but distinct doctrines, including cause of action estoppel; merger of a cause of action into a judgment; and the rule in Henderson v Henderson.
13. The Upper Tribunal in Vernon v Orbit Housing Association [2026] described the doctrine as follows:
“… once a court a has decided an issue that was an essential element in a party’s cause of action or defence, the parties cannot re-litigate that issue.”
14. In other words, once a court has made a finding in one set of proceedings, it is not open to another court to come to a contrary finding. The doctrine is, however, subject to important limitations and exceptions which must be carefully considered.
15. First, an issue estoppel can only arise between the parties to the original decision. As stated in Brunswick Railway Company v British and French Trust Corporation Ltd[6] as:
“If an issue has been distinctly raised and decided in an action, in which both parties are represented, it is unjust and unreasonable to permit the same issue to be litigated afresh between the same parties or persons claiming under them…”
16. Second, this all begs the question of what an “issue” actually is. Not all findings of fact give rise to an issue estoppel. The issue must be a central fact which is a necessary ingredient to the cause of action. As Lord Diplock stated in Thoday v Thoday [1964] 2 WLR 371 at [385]:
“Issue Estoppel” must not be confused with “fact estoppel” … The determination by a court of competent jurisdiction of the existence or nonexistence of a fact, the existence of which is not of itself a condition the fulfilment of which is necessary to the cause of action which is being litigated before that court, but which is only relevant to proving the fulfilment of such a condition, does not estop at any rate per rem judicatam either party in subsequent litigation from asserting the existence or non-existence of the same fact contrary to the determination of the first court”.
17. Third, the “issue”is what is left after that central fact has been stripped down to the minimum necessary to make out the case of action[7]. If a determination has been made, without which it would be possible for the decision to stand, the same cannot give rise to an issue estoppel.
18. Fourth, the “issue”that was determined in the earlier proceedings must be identical to that which now falls for determination (Brunswick Railway Company at [20]).
19. A few simple examples:
- In a breach of contract claim, factual findings in respect of offer/acceptance, payment of consideration, and breach, could all give rise to an issue estoppel. However, findings as to why the contract was entered, or the parties’ pre-existing relationship, or the financial circumstances which gave rise to the breach, would probably not give rise to issue estoppel; and
- In a trespass claim arising from a boundary dispute, findings as to the trespass itself, but also the boundary position (including, say, the ingredients of a boundary agreement) would give rise to issue estoppel. Findings as to harassment, or planning breaches, or any other aspects of a wider neighbour dispute would not.
EXCEPTIONS TO ISSUE ESTOPPEL
20. Even if the ingredients for issue estoppel apply, there are exceptions to its binding effect. This is to be contrasted with the related “cause of action estoppel”, which is absolute.
21. A commonly cited example is where “… further material which is relevant to the correctness or incorrectness of the assertion and could not by reasonable diligence have been adduced by that party in the previous proceedings has since become available to him”[8]. This is analogous to the Ladd v Marshall test.
22. There are two other important examples of exceptions, which both arise in service charge cases.
23. In Hemmise v London Borough of Tower Hamlets[9] the UT considered whether an earlier LVT’s interpretation of a lease could give rise to an issue estoppel. In that case:
- The earlier LVT’s decision was plainly wrong;
- The LVT had carried out the interpretation exercise without the parties inviting it to do so; and
- The slightly peripheral nature of the LVT’s decision meant that the landlord had not felt it necessary to appeal or challenge the decision the first time around.
24. The UT determined that issue estoppel would apply. However, in the peculiar circumstances, “perpetuation a wrong decision over the whole life of the lease” was a special circumstance for not finding the estoppel had binding effect.
25. In Francis v Sandoz[10] the UT considered whether an issue estoppel could arise in circumstances where there were already two previous inconsistent decisions on whether the cost of providing staff accommodation was, in principle, recoverable under the service charge provisions of a lease. The Upper Tribunal considered that avoiding such inconsistency was a further special circumstance that justified a departure from what may otherwise give rise to an issue estoppel.
26. Following from these cases, it was thought that some fairly peculiar circumstances were required before exceptions could be found to issue estoppel. It will be seen that Orbit v Vernon has potentially moved this along somewhat.
THE UT’S DECISION IN ORBIT v VERNON
27. To determine whether an issue estoppel arose, the Upper Tribunal in Vernon v Orbit started by examining precisely what had been found in the First FTT Decision and whether the same was capable of giving rise to an estoppel:
“… did it – as is argued for Mr Vernon – make a finding which was a “static fact” which remains true for the future? Or did it – as is argued for Obit – make a finding about “the facts on the ground” … in the years in question only?”
28. The concept of a “static fact” is likely to be a useful lens through which practitioners can consider whether individual issues may potentially give rise to an issue estoppel.
29. The Upper Tribunal concluded that the First FTT Decision was simply a consideration of the facts as they stood in the two service charge years in question. The absence of services in those two years in question did not amount to a “static fact” that would be binding in future service charge years. There had been no express finding, for example, on the interpretation of a contract between the Respondent and a third party care provider, or about the Respondent’s policies, or the state of the premises, which was capable of applying to future years. To go any further would be to draw impermissible inferences.
30. As such, the First FTT Decision was simply that the Appellant had received no benefit from the SBSC for those years then under consideration. There was nothing to prevent the FTT from reaching a different decision on what was happening in subsequent years; an issue estoppel had not arisen.
31. The UT did not therefore need to consider the Respondent’s additional arguments as to whether the findings in the First FTT Decision were of a sufficient centrality to be issues for the purposes of issue estoppel.
32. Perhaps more importantly, the Upper Tribunal went on to hold that an exception to issue estoppel would have applied. The Upper Tribunal stated that:
“The 2022 decision was plainly wrong, because the contractual arrangements with [the service provider] require it to provide a service for all residents and the factual evidence heard by the FTT in 2025 showed that it was doing so … It would be wrong for Orbit to be stuck with a position found by the FTT in 2022 which does not reflect the true position found by it in 2025 on the basis of clear and compelling evidence. Mr Vernon entered into a tenancy in a block providing sheltered housing and it would be wrong for him to be entitled to remain in that sheltered situation without making what the FTT found to be a reasonable payment for the service that is provided for him.”
33. This seems to be a clarification, if not expansion, of the expansion in Hemmise. Orbit v Vernon did not share any of the peculiar factors which existed in Hemmise. The exception applied solely because:
- The First FTT Decision had been shown to be demonstrably wrong; and
- The effect of an issue estoppel would impact on the parties’ ongoing relationship for an indefinite period of time.
34. This is a much clearer, and simpler, basis for an exception to issue estoppel. It is probably most applicable in cases of long or rolling leases, or long term contracts. It may however encourage estopped parties to fully litigate matters which are plainly subject to issue estoppel, on the hope that they can show the first decision was demonstrably wrong.
PARTICULAR SIGNIFICANCE TO SERVICE CHARGE CASES
35. Issue estoppel has a particular place in service charge cases, due to their nature. A few points to consider:
- Landlords may face similar challenges from multiple tenants within the same building. A determination in proceedings brought by one tenant will not give rise to an issue estoppel in proceedings brought by another;
- The FTT will frequently be tasked with the determination of the particular terms of a lease. It is well established that such an interpretation could form the basis of an issue estoppel, at least between the parties to that application;
- As has been seen, an interpretation which is plainly wrong may fall within the exception identified by Hemmise;
- Similar arguments are likely to also arise in respect of the interpretation of contracts between a landlord and third-party service providers. If a landlord has entered a contract with a third party that obliges particular services to be provided to a tenant, this will have a significant impact on the FTT’s determination as to reasonableness. The interpretation of that contract may readily give rise to an issue estoppel, if it is a central ingredient of the reasonableness determination;
- Other findings may be made by the FTT that can be described as ‘static facts’, relevant to subsequent years. For example, if service charges should be apportioned based upon the square footage of a block, the determination of the square footage made by the FTT could form the basis of an issue estoppel in subsequent years. Practitioners may be mindful of the arguments that could be advanced should that square footage determination be obviously wrong. The exception in Mills v Cooper [1967] may be applicable if further evidence was obtained that could not by reasonable diligence have been adduced by that party in the previous proceedings. However, following both Hemmise and Orbit v Vernon, continuing to adopt the same incorrect calculation of the square footage would result in the perpetuation of a wrong decision over the life of the lease. Another good example would be the FTT’s findings as to how the metering of utilities worked within a particular block; and
- Careful consideration should always be given to the dichotomy between findings of what is happening “on the ground” and “static facts”. Where the provision of a service is dependent on the landlord’s discretion, it is difficult to see how any findings relating to reasonableness could be “static” as that discretion would be re-exercised each year. On the other hand, findings of facts which might inform that discretion (such as, say, the building layout or existence of other services) could be “static”, but might not be of sufficient centrality to the determination to constitute issues.
CONCLUSION
36. The decision in Vernon v Orbit provides a clear and practical application of issue estoppel. It provides a helpful way of identifying the “issues”, drawing a clear distinction between “static facts” and those which are time limited.
37. The decision also potentially advances the scope of the exceptions to issue estoppel having a binding effect.
38. These points are likely to be of particular importance to practitioners navigating repeat service charge disputes.
39. As a final point, we remain exceptionally grateful to Danielle Sodhi of Shakespeare Martineau for her instructions in this important case.
