India [(1979) 3 SCC 489 : AIR 1979 SC 1628 : (1979) 3 SCR 1014] and the other in Ashok Kumar Mishra v. Collector [(1980) 1 SCC 180 : AIR 1980 SC 112 : (1980) 1 SCR 491] . We may point out that in R.D. Shetty case, even though the State action was held to be unconstitutional as being violative of Article 14 of the Constitution, this Court refused to grant relief to the petitioner on the ground that the writ petition had been filed by the petitioner more than five months after the acceptance of the tender of the fourth respondent and during that period, the fourth respondent had incurred considerable expenditure, aggregating to about Rs 1.25 lakhs, in making arrangements for putting up the restaurant and the snack bar . Of course, this rule of laches or delay is not a rigid rule which can be cast in a strait jacket formula, for there may be cases where despite delay and creation of third party rights the High Court may still in the exercise of its discretion interfere and grant relief to the petitioner. But, such cases where the demand of justice is so compelling that the High Court would be inclined to interfere in spite of delay or creation of third party rights would by their very nature be few and far between. Ultimately it would be a matter within the discretion of the court; ex hypothesi every discretion must be exercised fairly and justly so as to promote justice and not to defeat it.”
