7G.—Where it comes to the knowledge of the Executive that—

(a) all or part of the payment of a relevant subvention to a dependent person has been procured through fraud or misrepresentation, or

(b) there has been an overpayment of a relevant subvention to, or in respect of, a dependent person,

then the amount of that payment so procured, or of that overpayment, as the case may be, shall be repayable to the Executive on demand and, if not so repaid, the Executive may recover the amount, as a simple contract debt in any court of competent jurisdiction, from the dependent person to whom the payment or overpayment, as the case may be, was made or the estate of that person.]
