THE INGREDIENTS OF A BINDING CONTRACT
In RTS Flexible Systems Ltd v Molkerei Alois Müller GmbH & Co KG (UK Production)
[2010] UKSC 14, [2010] 1 WLR 753, the Supreme Court allowed an appeal from the decision of the Court of Appeal (on which see
our March 2009 issue, pp4-7) and held that the parties had entered into a binding contract. In doing so, the Supreme Court
affirmed that, when deciding whether parties have concluded a binding contract, a court has regard, not to the subjective
understandings of the parties, but to what was communicated between them by words or conduct, and whether that leads objectively
to a conclusion that they intended to create legal relations and had reached agreement on all essential terms. On the facts
of the present case, these requirements were satisfied. Although clause 48 of the draft written contract provided that the
contract would ‘not become effective until each party has executed a counterpart and exchanged it with the other’ the parties
were held to have agreed to waive this ‘subject to contract’ stipulation so that it was no barrier to the existence of a binding
contract between the parties.
