Having heard the learned counsel on either side for a considerable length of time, we are clearly of the view on a conspectus of the relevant Section 13(B) of the Act and on the factual matrix of the case that the result of the case would depend upon the decision of two substantial questions involved, they being (1) Whether respondents 1 and 2 are bona fide purchasers of the scheduled land in dispute for adequate consideration entitling to the benefit of the proviso to Section 13(B)(1)? (2) Whether the appellants are entitled to the benefit of subSection (1) of Section 13(B) of the Act? Before making a more detailed and searching analysis on different aspects of the case, it would be necessary for proper understanding of the issues involved to reproduce the relevant provisions of Section 13(B)(1) of the Act, on the pivotal of which both the questions revolve.
