If, for any reason (including the making of, or cancellation of, an election under the Trust Deed), CSC has paid an amount of benefit that was, or has become, not payable:
(a) the amount so paid may be recovered by CSC in a court of competent jurisdiction as a debt; or
(b) if the person to whom that amount was paid is receiving, or is entitled to receive, a benefit under the Trust Deed--the amount so paid, or such part of that amount as CSC determines, may, if CSC so directs, be recovered by deduction from that benefit.
