3.—(1) Where as well as any relevant child there are other children to whom special allowances are payable in respect of the death of the same person and either of the relevant provisions applies, the special allowances payable to those other children (“the other special allowances”) shall be increased as provided in this paragraph.
(2) If paragraph 2(a) applies in the case of any relevant child, then, without prejudice to sub-paragraph (3), the annual amount of each of the other special allowances shall be increased by an amount equal to his excess remuneration divided by the number of other special allowances.
(3) If paragraph 2(b) applies in the case of any relevant child, then, without prejudice to sub-paragraph (2), each of the other special allowances shall be recalculated as if the relevant child were not entitled to a special allowance.
(4) Notwithstanding the provisions of sub-paragraphs (2) and (3), no child shall by virtue of these provisions receive a special allowance greater than that to which he would be entitled if no relevant provision applied in his case.
