Ha ye. That's not a bad legal pun as they go.
Jjarvis- it was Russell LJ who thought estoppel could have been run as an argument- but you're right to say it was obiter sadly.
And Arden LJ- I'm a bit confused- are you talking about the Collier case? You'll just have to clarify for me.
The issue of when something constitutes a factual benefit is very (academically) controversial. Here's my take on it, from my dissertation, it's not the most original bit of it by any means- but hopefully it will clarify the issue for you. As you can see, I am not altogether happy about the state of the law post Roffey.
(iii.) Roffey; A Flawed Judgment?
Roffey is arguably the most notorious “exception” to Stilk. The facts were that the plaintiffs agreed to carry out building works for the defendants at a fixed price. It became apparent the plaintiffs would become insolvent unless supplied with more money. Moreover, if the work was incomplete by a deadline, then the defendants were liable for delay penalties. Consequently the parties mutually agreed a higher sum for the completion of the works. Naturally the defendants relied on Stilk to suggest the revised agreement was unenforceable. However, in a controversial decision the Court of Appeal found that consideration was sufficient if “factual and practical” benefits flowed from the bargain.
Generally the judgments were reasonably well-received by academia and it is suggested that the correct result was generated. That said, although Roffey was clearly well-intentioned it has caused uncertainty. The problems centre on the definition of “factual and practical” benefit. In coming to their decision, the Court cumulatively suggested that four “practical benefits” were material: (1) the evasion of a breach of contract by the plaintiffs, (2) the fact that no substitute performer was required by the defendants, (3) the avoidance of the penalty clause and (4), the replacement of “a haphazard method of payment…by a more formalised system.” Whilst the use of these factors appears reasonable on the particular facts of Roffey, it is difficult to envisage how the judgment could be consistently applied. For instance, the first two criteria necessarily pertain to all contractual relations. Thus, if they were, by themselves, able to constitute good consideration, this would effectively vitiate the need for the doctrine entirely; a result the judges clearly attempted to avoid. Conversely, the latter two requirements were peculiar to Roffey and would not necessarily provide concrete assistance in similar cases. In reality, it is submitted that the Court felt it inequitable for the defendants to escape the additional payment they had promised and resorted to deliberately ambiguous language in order to arrive at a just conclusion. Nevertheless, the problems with this lack of clarity are highlighted by Colman J’s subsequent scathing treatment of the case in South Caribbean Trading Ltd v. Trafigura Beheer BV.
As such, precise guidance as to the exact constitution of “factual and practical benefits” should have been given. That said, given the historical background of Stilk, there should have been no qualms about simply rejecting Lord Ellenborough’s dicta (or at least the conventional interpretation of them). The law, it is maintained, would have been much clarified if the Court had grasped the opportunity to restate the law completely and rejected the notion that pre-exiting duties could not constitute good consideration. This truly would have created a law reflecting modern commercial realities.
