Mexfield Housing Co-operative Ltd v Berrisford [2011] UKSC 52: Issues and Reasoning

Introduction

The decision of the Supreme Court in Mexfield Housing Co-operative Ltd v Berrisford [2011] UKSC 52 is a significant case in modern English land law, particularly concerning the requirement for certainty of term in leases. The case demonstrates the judiciary's use of an old, and some thought obsolete, common law rule to navigate the strict requirements of property law and achieve a result that protected a residential tenant from eviction. The traditional rule, reaffirmed in Prudential Assurance Co Ltd v London Residuary Body [1992] 2 AC 386, is that a lease must have a fixed and ascertainable maximum duration from the outset. The agreement in Mexfield appeared to fail this test, creating a legal problem for the court. This note will explain the key issues faced by the Supreme Court and detail the reasoning it employed to resolve the dispute in favour of the tenant, Ms Berrisford.

The Factual Background

The case concerned an agreement between Mexfield Housing Co-operative Ltd (‘Mexfield’) and Ms Berrisford. Mexfield was a fully mutual housing co-operative, which had been set up as part of a mortgage rescue scheme. Ms Berrisford had faced difficulties paying her mortgage and, under the scheme, sold her property to Mexfield, who then leased it back to her.

The agreement, described as an "occupancy agreement", stated that it was granted "from month to month". However, it also contained specific clauses setting out how it could be terminated. Clause 5 allowed Ms Berrisford to end the agreement by giving one month's notice. Clause 6 stated that Mexfield could only end the agreement if Ms Berrisford was in rent arrears, had breached a term of the agreement, or had ceased to be a member of the Co-operative.

The problem arose when Mexfield served a notice to quit on Ms Berrisford, giving her one month's notice, based on the argument that she held a simple monthly periodic tenancy which could be terminated by either party for any reason. Ms Berrisford had not breached any terms of the agreement, so the conditions in Clause 6 were not met. She argued that Mexfield could not evict her unless one of the conditions in Clause 6 was satisfied. The case therefore turned on the legal nature of the agreement she held.

The Legal Issues

The County Court and the Court of Appeal both found in favour of Mexfield. They held that the agreement, because its duration was uncertain, could not create a valid lease for a term. The ending events specified in Clause 6 (such as rent arrears) might never happen, so the maximum term of the lease was not known at the start. Following the authority of Prudential Assurance, the courts below concluded that the uncertain term meant that only a periodic tenancy could exist. As the rent was paid monthly, this was a monthly periodic tenancy, which a landlord can terminate by giving one month’s notice.

The Supreme Court had to address the following key legal issues:

1. Did the agreement, on its face, satisfy the certainty of term requirement for a valid lease?
2. If the term was uncertain, what was the legal effect of the agreement? Was it, as the lower courts found, a simple periodic tenancy that could be terminated by notice, despite the express terms of the agreement to the contrary?
3. Could an old common law rule, which treated a lease for an uncertain term granted to an individual as a tenancy for life, be applied?
4. If so, what was the effect of section 149(6) of the Law of Property Act 1925 (LPA 1925) on such a tenancy?

The Supreme Court's Reasoning

The Supreme Court unanimously allowed the appeal, finding in favour of Ms Berrisford. The leading judgment was given by Lord Neuberger, with whom Lords Walker, Hope, Mance and Collins agreed. Lady Hale and Lord Dyson gave concurring judgments.

Lord Neuberger’s reasoning proceeded in several logical steps.

Confirmation of the Certainty of Term Rule

First, the Court confirmed that the long-established rule requiring a lease to have a certain term remains a part of English law. Lord Neuberger acknowledged that the rule had been criticised as having no practical justification (Dixon, 2021), but felt bound by the House of Lords' decision in Prudential Assurance. The agreement between Mexfield and Ms Berrisford, being terminable only on the occurrence of uncertain future events, did not have a certain maximum duration. Therefore, it failed to create a valid lease according to its own terms.

The Effect of an Uncertain Term at Common Law

The crucial part of the reasoning was the Court’s revival of a pre-1926 common law principle. Lord Neuberger explained that, before the LPA 1925 came into force, an agreement for a lease of uncertain duration granted to an individual was treated by the common law as a tenancy for life. The logic was that since the person's life was itself of uncertain duration, an agreement that could last for that person's lifetime was considered a tenancy for life, determinable on the earlier occurrence of the specified events. The agreement in this case, being for an indefinite period but terminable on events linked to Ms Berrisford’s tenancy (such as her falling into arrears or giving notice), was exactly the sort of arrangement that the common law would have interpreted in this way.

The Statutory Conversion under the Law of Property Act 1925

The third step was to consider the impact of the LPA 1925 on this common law position. Section 149(6) of the Act provides that any "lease… at a rent… for the life or lives of any person or persons… shall take effect as a lease… for a term of ninety years determinable" after the death of the original lessee.

By applying this statutory provision, the Supreme Court reasoned as follows:

1. The agreement between Mexfield and Ms Berrisford, due to its uncertain term, would have been treated as a tenancy for her life at common law.
2. Section 149(6) of the LPA 1925 applies to such tenancies for life.
3. Therefore, the agreement was statutorily converted into a lease for a fixed term of 90 years.
4. This 90-year lease was determinable (i.e., could be ended earlier) either upon Ms Berrisford’s death, or by her giving notice, or by Mexfield if one of the grounds in Clause 6 of the original agreement was met.

This interpretation had the effect of validating the original intention of the parties. It meant that Ms Berrisford had a secure tenancy that could not be ended by a simple notice to quit from the landlord; Mexfield was bound by the restrictive termination clauses they had agreed to. The court distinguished Prudential Assurance on the grounds that the s.149(6) argument had not been raised in that case, allowing them to reach a different outcome without formally overruling the precedent.

Concurring Judgments and Criticisms of the Rule

While all the judges agreed on the outcome, several expressed dissatisfaction with the state of the law. Lady Hale described the law on certainty of term as "a bizarre outcome" and stated that there was "no apparent practical justification for holding that an agreement for a term of uncertain duration cannot give rise to a tenancy" (Mexfield at [89]-[93]). Lord Walker also noted the criticisms of the rule. This shows a judicial appetite for reform, even though the Court did not take the step of abolishing the certainty rule in this case. They were able to find a "workaround" that avoided a direct confrontation with established precedent while achieving what they saw as a just result.

Conclusion

The decision in Mexfield v Berrisford is a striking example of judicial creativity. Faced with a conflict between the parties' clear intentions and a rigid, arguably outdated, common law rule, the Supreme Court reached back into legal history to find a solution. By reviving the principle that an uncertain term for an individual creates a lease for life, and then applying the statutory conversion mechanism in section 149(6) of the LPA 1925, the Court transformed the agreement into a valid 90-year lease. This protected Ms Berrisford’s security of tenure and upheld the terms she had agreed with the co-operative.

However, the solution is not without its limitations. The reasoning relies on the tenant being a human being, as a company cannot have a 'life' in the same way. In a subsequent case, Southward Housing Co-operative Ltd v Walker [2015] EWHC 1615 (Ch), the High Court decided that the Mexfield approach could not be used where the parties’ intentions clearly pointed away from creating a life tenancy. The decision in Mexfield therefore provides a clever but narrow escape route from the certainty of term rule, rather than a comprehensive solution. It solved the immediate problem for Ms Berrisford but left the controversial Prudential rule intact, leaving the law in this area in a state that many commentators, and indeed some of the judges themselves, consider unsatisfactory.
