Jonathan Parker J held Collins had overpaid Davis and Satterfield and he was entitled to set future royalties off against half of the sums overpaid. He said the overpayment was a mistake of fact, because Collins thought they had played in all 15 tracks. Collins was not estopped from maintaining there was overpayment of royalties because there was never any assumption between the parties that Davis and Satterfield would get royalties for all 15 tracks and there was no acquiescence in the assumption. Overpayment was not acquiescence. There was no evidence Davis and Satterfield ever thought they were entitled. The overpayments did not amount to representations that they were (so no
estoppel by representation). But the fact of overpayment did result in a general change of position on Davis and Satterfield's part. It increased their level of outgoings. However, the defence of change of position was not an “all or nothing” doctrine and, in this case, it would be fair to allow the defence to cover one half of the overpayments (
Lipkin Gorman v Karpnale Ltd [1991] 2 AC 548 applied). Finally, if Collins had made a claim to recover the overpayments his claim would have been statute barred under the
Limitation Act 1980, s.5 because it was six years. But here it was not a return of overpayments, only an equitable set off against future royalties. The following is an excerpt about the change of position defence at work. ==See also==
