Co-operative Insurance Society Ltd v. Argyll Stores

Factual and Procedural Background

Company B operated a supermarket within a shopping centre owned by Company A. Under the 35-year lease, Clause 4(19) obligated Company B to “keep the demised premises open for retail trade during the usual hours of business.” In May 1995 Company B closed the loss-making store, stripping out its fittings and thereby breaching the covenant. Company A promptly issued a writ seeking specific performance and damages.

At first instance, Judge [Maddocks] refused specific performance and ordered damages to be assessed. The Court of Appeal reversed, granting a mandatory injunction compelling Company B to reopen and trade until assignment or lease expiry (3 August 2014). Company B appealed to the House of Lords. By the time of the appeal the lease had been assigned, so the mandatory injunction never operated; the dispute focused mainly on the propriety of granting such relief and the ensuing costs.

Legal Issues Presented

1. Whether a court should order specific performance (by way of a mandatory injunction) compelling a tenant to carry on a commercial business pursuant to a “keep-open” covenant.
2. Whether the Court of Appeal was entitled to overturn the trial judge’s discretionary refusal to grant such relief.

Arguments of the Parties

Appellant's (Company B) Arguments

• The settled practice of English courts is not to compel parties to run a business; damages are the appropriate remedy.
• Specific performance would require constant judicial supervision and rely on contempt proceedings—an unsuitable enforcement mechanism.
• The covenant’s wording (“keep open for retail trade”) is too imprecise to be policed effectively.
• Forcing the supermarket to reopen would impose disproportionate losses and give Company A an unfair bargaining position.

Respondent's (Company A) Arguments

• Damages would be difficult to quantify and would not fully compensate for the loss of the supermarket’s “magnet” effect on the shopping centre.
• Modern case-management techniques minimise supervision difficulties; the court should simply make the order and deal with issues if they arise.
• Company B’s conduct was commercially cynical, justifying equitable intervention.

Court's Reasoning and Analysis

The House emphasised that specific performance is a discretionary, exceptional remedy. It reaffirmed a settled practice: courts do not compel parties to run a business because:

• Supervision & Contempt: Enforcing an ongoing business obligation necessitates potentially endless applications to determine compliance, with contempt proceedings an unduly heavy enforcement tool.
• Imprecision: The clause “keep open for retail trade” lacks objective benchmarks on product range, trading intensity, or staffing, making any order vague and litigation-prone.
• Economic Waste & Oppression: Forcing Company B to trade at a loss could enrich Company A beyond its contractual expectation and saddle both parties, and the court system, with protracted conflict.
• Alternative Remedy: Although damages may be complex to assess, they remain the proper, once-and-for-all solution.
• No Exceptional Equity: Both companies were sophisticated commercial actors; no element of personal trust or bad-faith bargaining justified departing from the usual rule.

Accordingly, Judge [Maddocks] had exercised his discretion soundly. The Court of Appeal erred by treating supervision concerns as outdated, underestimating imprecision, and over-emphasising Company B’s conduct.

Holding and Implications

Appeal ALLOWED. The order granting a mandatory injunction is set aside, and the trial judge’s refusal of specific performance is restored; damages remain to be assessed.

Implications: The decision consolidates the longstanding principle that English courts will not compel a defendant to carry on a commercial enterprise. Landlords seeking to enforce “keep-open” clauses must ordinarily rely on damages rather than mandatory injunctions. The ruling provides certainty for commercial actors and preserves judicial resources, without creating new precedent outside established doctrine.
