‘There are two respects in which an overpayment may undoubtedly be split so that part is recoverable and part not. I have already referred to the distinction drawn in regulation 99 between overpayments that were caused by official error and those that were not. As I have said, I accept the point made by Ms Jackson on this AG v Calderdale Council (HB)[2016] UKUT 396 (AAC) CH/1633/2016 CH/1633/2016 4 distinction. The legislation also requires, when appropriate, that an overpayment is split by reference to time. The focus of attention under regulation 99(2) is on the time of ‘the payment’ or notice of the payment. That requires an individual consideration for each payment or notice. And that inevitably requires the overpayment to be split by reference to time if different considerations applied at different times so that the claimant could reasonably have been expected to realise that an overpayment was being made for part of the time but not for the remainder.’
‘an overpayment should be looked at as a series of payments’
‘The notices dated15 August 2000 were clearly “relating to that payment” within the meaning of Reg. 99(2). No doubt some limitation must be placed on the word “any” in the phrase “any notice relating to that payment” so that a notice which is not sufficiently closely related to receipt of the payment must be disregarded for this purpose. But here the notices were the first written notification of the payment and were received by the Claimant at or about the same time as she became aware of the payment.’
