Case Facts
The council owned and managed Blackpool Airport and had, on three previous occasions (in 1975, 1978, and 1980), granted a concession to the club permitting it to operate pleasure flights from the airport for revenue purposes. In early 1983, the council decided to invite tenders for a new concession. Invitations to tender were sent to the club and six other parties, all of whom were connected with the airport — a total of seven selected, identified parties known to the council.
The invitation to tender prescribed a clear and orderly procedure. Tenders were to be submitted in a specially provided envelope, pre-printed by the council with the words "Tender for Pleasure Flying Concession" and the deadline "Due in 12 noon Thursday 17 March 1983". The envelope was not to bear any name or mark identifying the sender, thereby preserving the absolute anonymity of tenderers. An absolute deadline of 12 noon on 17 March 1983 was imposed, and the council's standing orders expressly provided that no tender received after that deadline would be admitted for consideration. Draft contract conditions were available for inspection but were not open to negotiation.
Only three of the seven invited tenderers responded: the club, one party submitting a low bid covering lighter aircraft only, and Red Rose Helicopters Ltd, submitting a larger bid also relating to lighter aircraft.
The club's tender was deposited in the Town Hall letter box at 11 am on 17 March 1983 — a full hour before the deadline. However, the letter box was not cleared by council staff at noon as it should have been. As a result, the club's tender was recorded as having been received after the deadline and was not considered. The concession was awarded to another tenderer. The club brought proceedings against the council, and at first instance Judge Jolly held the council liable for breach of contract and in negligence. The council appealed.
Held
The Court of Appeal dismissed the council's appeal. In certain circumstances, an invitation to tender sent to selected, identified parties can give rise to a binding implied contractual obligation on the part of the invitor to open and consider any conforming tender submitted before the deadline. The council had breached that implied obligation by failing to consider the club's tender, which had been submitted on time, due to the council's own staff failing to clear the letter box. The club was entitled to damages for breach of that implied contract.
Ratio Decidendi
The central principle established is that where an invitation to tender is made to a limited number of selected, identified parties — rather than to the world at large — and where the invitation prescribes a clear, orderly, and familiar procedure with an absolute deadline, an implied contractual obligation arises on the part of the invitor to open and consider any conforming tender submitted before that deadline.
This implied obligation was grounded in the particular circumstances of the tender process. Tenders were solicited from seven specifically chosen parties, all known to the council. The prescribed procedure was carefully structured: it required submission in an anonymised envelope with no identifying marks, imposed an absolute and non-negotiable deadline, and was backed by standing orders expressly excluding late tenders from consideration. In these circumstances, it was to be implied that if an invitee submitted a conforming tender before the deadline, that invitee would be entitled as a matter of contractual right to have its tender opened and considered alongside any other tenders that were considered.
A critical distinction must be drawn between this type of selective, structured invitation and a general circular invitation to tender addressed to the world at large. In Spencer v Harding (1870), it was established that a general circular invitation to tender is no more than an invitation to treat: it creates no obligation on the invitor to accept any tender, nor to consider any particular response. The present case differed materially because the invitation was directed to a small group of identified, selected parties connected with the airport. The reasonable expectations of those parties — that compliance with the prescribed procedure would entitle them to have their tender considered — warranted legal protection through an implied contract. The council's failure, through its own administrative shortcoming, to consider the club's timely and conforming tender therefore constituted a breach of that implied contractual obligation.
It is important to note that this ratio does not establish a broad general duty on public bodies to act reasonably in all contracting situations. Rather, the obligation is a narrow and specific one, arising from the combination of a selective tender process, a structured and familiar procedure, and conditions designed to ensure fairness and anonymity amongst the invited parties.
Obiter Dicta
The court observed, by way of contrast with the ratio, that a general invitation to tender — of the kind considered in Spencer v Harding (1870) — would not ordinarily give rise to any implied contractual obligation on the part of the invitor. Where an invitation is broadcast to the public or an indeterminate class of persons, there is no basis for implying an obligation to consider responses. It is only where a selective and structured invitation is made to identified parties, with prescribed conditions designed to ensure an orderly and fair process, that the law will imply an obligation to consider conforming tenders. This distinction is essential: the implied obligation recognised in this case exists to protect the reasonable expectations of those specifically invited to participate in a tender process that they are entitled to trust will be conducted fairly.
