We are concerned in these matters only with the period from the date of expiry of the contracts in favour of each of the respondents to 30.1.1987 and with the following questions: (a) whether the O.N.G.C. is at liberty to fix its own price for the gas or should be directed to fix the price in any particular manner; (b) whether the O.N.G.C. can be directed to supply data and the break up for the price charged and to negotiate the price with the par ties concerned; (c) whether the 171 O.N.G.C. can be compelled to continue to supply gas to the various petitioners at the interim prices fixed by the court subject to adjustment on fixation of prices determined in accordance with the directions of the court; and (d) whether the minimum guarantee of off take could be raised by the O.N.G.C. to 90 per cent instead of 75 per cent.
