( 1 ) A large number of writ petitions have been filed in this Court challenging the validity of certain declarations under S. 6, Land Acquisition Act, (1 of 1894) hereinafter referred to as the Act on the ground that they had been made after the expiry of the period prescribed therefor under the said section. C. W. 1639/85 and 15 other of these petitions were heard by Yogeshwar Dayal and S. B. Wad, JJ. in November, 1985 and judgment was reserved. In the meanwhile, R. N. Aggarwal and Malik Sharief-ud-din, JJ. had heard CW 2850/1985 involving the same issue and delivered judgment on 25-8-1985 upholding the validity of the declaration under S. 6. Since Yogeshwar Dayal and Wad, JJ, were inclined to take a different view, they suggested that the issue may be decided by a Larger Bench, and hence the constitution of this Full Bench. As many as 73 writ petitions have been listed before us and, when we heard these matters, we found that the petitioners in all these cases have also raised several contentions other than the main one referred to above. The result is that, if we decide the above principal issue in favour of the petitioners, all the writ petitions can stand
