(4) In any week in respect of which a coal industry employee is entitled to receive under paragraph (3) an addition to the basic benefit, the aggregate of the basic benefit and that addition shall be reduced or extinguished by deducting therefrom an amount equal to the aggregate of the payments and amounts referred to in sub-paragraphs ( a ) and ( b ) of paragraph (1) which such employee is entitled to receive in respect of that same week.
(5)
(a) Where any coal industry employee eligible for payments under this Scheme has, between the relevant date and the making of this Order, received a lump sum payment, not being a refund of contributions, under the Staff Superannuation Scheme, then, for every week in respect of which he is entitled to receive the basic benefit, the amount of such benefit, after adjustment if appropriate in accordance with the preceding paragraphs of this Article, shall be reduced or extinguished by deducting therefrom an amount calculated at the rate of one shilling for each £50 of that lump sum payment.
