13.—(1) Subject to paragraph (2), where an application relates to any of the proceedings specified in regulation 6 (distinct proceedings), and the applicant was previously an assisted person in relation to that matter, the Board must not redetermine the applicant’s disposable income and disposable capital but must assess the amount of the maximum contribution, if any, payable in respect of the proceedings at an amount not greater than the maximum contribution assessed in relation to the earlier proceedings, less any amount assessed by the Board to be paid in respect of those proceedings.
(2) If since the last occasion on which the disposable income and disposable capital of the person concerned was determined in relation to that matter, that person’s circumstances have altered otherwise than as a result of the payment of a contribution in respect of the earlier proceedings, the Board may redetermine that person’s disposable income and disposable capital in accordance with the law applicable at the time of the original determination and must take into account—
(a)any increase in the amount of that person’s disposable income by an amount greater than £750;
(b)any decrease in the amount of that person’s disposable income by an amount greater than £300; and
(c)any increase in the amount of that person’s disposable capital by an amount greater than £750.
