Well, the claimant in the present case was not secondarily liable. He simply spent his own money on himself. Whether he was entitled to choose his own services and seek reimbursement involved a question of statutory construction. You are right to say the
source of the right will not always arise out of a statute; it may be a contract as in the guarantee situation to which your refer (the contract with the creditor). But in order to know whether the import house was secondarily liable in Brook’s Wharf one had
to construe the statute, and divine the intention of the drafter. Once one has done that it is more sensible in my view to treat the obligation of one party to reimburse the other as arising out of statutory implication than out of the air through a common
law cause of action (including one in unjust enrichment). I admit equitable contribution is more problematic to analyse in this way. Peter.
Thanks for this Peter.
Why does there need to be a statute? Isn’t it (at least if the plaintiff’s argument is correct) the same type of claim that has always been available where a person who is only secondarily liable pays a debt that someone else was primarily liable to pay?
Of course the primary/secondary question may require statutory interpretation, but this is not the case, for example, where a guarantor pays the debt of a primary debtor—the analogy that was, I think, relied upon in Brook’s Wharf.
On that view, mistake is irrelevant—but I don’t think mistake was part of the claim in Brook’s Wharf. The conclusion about primary/secondary is enough to tell you that something is not as it should be as between the person who paid and the person who was
primarily liable to pay.
Whether unjust enrichment is relevant to this claim is a much more difficult question..

More unjust-enrichment madness, as I see it, out of the English courts yesterday. Again only a strike out decision, but there will be many more of those whilst a free-ranging unjust enrichment concept is on the loose.
