4.—(1) The provision of the next succeeding paragraph of this article shall apply to a person who, before the operative date, was entitled to compensation under a Silicosis Scheme together with a lesser incapacity allowance under article 5 of the Workmen's Compensation (Supplementation) Scheme 1966(1) which amounted, in the aggregate, to a sum greater than the allowance in respect of partial disablement under the Pneumoconiosis, Byssinosis and Miscellaneous Diseases Benefit Scheme 1966 to which he is entitled by virtue of article 2 of this scheme.
(2) A person to whom the last preceding paragraph applies shall, notwithstanding the revocation of the Silicosis Schemes, be treated as entitled to benefit under the Pneumoconiosis, Byssinosis and Miscellaneous Diseases Benefit Scheme 1966 at the rate or rates to which he would have been entitled if such revocation had not taken place and this scheme had not been made and he shall continue to be so entitled until such time, if ever, as his entitlement to partial disablement allowance under the Pneumoconiosis, Byssinosis and Miscellaneous Diseases Benefit Scheme 1966 equals or exceeds the aggregate sum referred to in the preceding paragraph of this article.
