The Court of Appeal upheld the finding at trial of HHJ Bird (sitting in the High Court) that save where there is fraud, a debtor is not legally obliged to volunteer information to an assignee regarding his arrangement with the assignor. The dispute arose because Bibby, a factor (and ‘Assignee’), purchased debts from Morleys Ltd (‘the Assignor’), owed to it by HFD Ltd and MCD Ltd (the ‘Customers’/‘Debtors’). The contract between the Assignor and Customers was such that the latter were entitled to a rebate, at the beginning of each calendar year, on purchases made.
