‘6. Shri Prem Malhotra, the learned counsel for the respondent, contended that since the respondent had refused performance the suit must be deemed to have been filed on 2312-1987 and, therefore, when the amendment was allowed, it would relate back to the date of filing the suit which was filed within three years from the date of the refusal. Accordingly, the suit is not barred by limitation. Shri U.R. Lalit, the learned Senior Counsel for the appellant, contended that in view of the liberty given by the High Court the appellant is entitled to raise the plea of limitation. The suit filed after expiry of 3 years from 1986 is barred by limitation. The question is: as to when the limitation began to run? In view of the admitted position that the contract was to be performed within 15 days after the injunction was vacated, the limitation began to run on 6-4-1986. In view of the position that the suit for perpetual injunction was converted into one for specific performance by order dated 25-8-1989, the suit must be deemed to have been instituted on 25-8-1989 and the suit was clearly barred by limitation. We find force in the stand of the appellant. We think that parties had, by agreement, determined the date for performance of the contract. Thereby limitation began to run from 6-4-1986. Suit merely for injunction laid on 23-12-1987 would not be of any avail nor the limitation began to run from that date. Suit for perpetual injunction is different from suit for specific performance. The suit for specific performance in fact was claimed by way of amendment application filed under Order 6 Rule 17 CPC on 12-9-1979. It will operate only on the application being ordered. Since the amendment was ordered on 25-8-1989 the crucial date would be the date on which the amendment was ordered by which date, admittedly, the suit is barred by limitation. The courts below, therefore, were not right in decreeing the suit.’
