If the District Court finds that by reason of the omission of Explanation (iv) by U.P. Act No. 28 of 1976 respondent No. 3 is no .longer entitled to rely on it to sustain her claim for release of the rented premises in her favour, it will be unnecessary for the District Court to examine the further question as to whether Explanation (iv) is attracted on the facts of the present case, If, on the other hand, District Court finds that the omission of Explanation (iv) by U.P. Act No. 28 of 1976 being prospective and not retrospective, respondent No. 3 is entitled to avail of that Explanation, the District Court will proceed to decide whether the two tenements or the .around floor constituted one single unit of accommodation so as to attract the applicability of Explanation (iv) and for this purpose, the District Court may, if it so thinks necessary, either take further evidence itself or require further evidence to be taken by the Pre scribed Authority.
