Marks and Spencer plc v BNP Paribas Securities Services Trust Company (Jersey) Ltd [2015] UKSC 72
Facts
Marks and Spencer occupied premises under a detailed commercial lease requiring rent quarterly in advance. It exercised a break clause ending the lease partway through a quarter after paying the full instalment due. The lease also specified conditions and payments associated with the break, but did not expressly require repayment of the unused portion of advance rent. The tenant claimed an implied entitlement to that amount. The dispute required the Supreme Court to consider the tests for implication in fact, their relationship with interpretation and the legal background governing rent payable in advance.
Legal Issue
Was a term requiring repayment of advance rent for the period after the break date necessary or obvious enough to be implied into the detailed lease?
Held
The Supreme Court refused to imply a right to repayment of the advance rent attributable to the period after the break date. The detailed, professionally negotiated lease worked without that addition, and the proposed term was not necessary for business efficacy or so obvious that it went without saying. Fairness or the fact that reasonable parties might have agreed a refund was insufficient. The majority distinguished construing express language from adding an implied term, even though both exercises consider contractual context. The established position concerning rent payable in advance formed part of that context. The decision did not prevent parties from expressly agreeing apportionment or repayment in a differently drafted lease.
⭐ Legal Principle
A term is not implied into a detailed commercial contract merely because it seems fair or would have been reasonable to agree. Implication in fact requires the established stringent conditions, including business necessity or obviousness, clear expression and consistency with the express bargain.
Significance
Marks and Spencer is a central modern statement on implied terms and the limits of using commercial common sense to supplement a contract. It clarifies that Belize Telecom did not dilute the traditional tests. The lease context also shows why background law matters: parties negotiate against existing rules and can expressly choose a different allocation. For an application problem, construe the express provisions first, identify the exact proposed term and explain why the agreement would lack the necessary practical coherence without it.
Common exam questions about this case
Why was a fair refund not enough to imply the term?
Implication is not a power to improve a bargain after an unforeseen disadvantage emerges. The detailed lease remained commercially workable without repayment. The tenant therefore needed more than fairness or a plausible account of what reasonable parties might have accepted if asked.
Must business necessity and obviousness both independently be proved?
The judgment accepted that those formulations can operate as alternatives, although they commonly point in the same direction. Other requirements, including consistency with express terms and clear formulation, remain relevant. The important point is the demanding threshold, not turning the tests into a mechanical cumulative checklist.
Does the decision prohibit express repayment clauses?
No. Parties can provide expressly for apportionment or repayment after a break. The issue was whether the court should insert such a term into this lease. A differently drafted agreement must be interpreted on its own wording, including any clear mechanism for allocating advance payments.
