the defendants had refused to admit the claim of the plaintiffs. Admittedly, the suit was filed on 218-1990. According to the averments made by the plaintiffs in their plaint, as noted hereinabove, if this statement is accepted, the question of holding that the suit was barred by limitation could not arise at all. Accordingly, we are of the view that the right to sue accrued when a clear and unequivocal threat to infringe that right by the defendants when they refused to admit the claim of the appellants i.e. only seven days before filing of the suit. Therefore, we are of the view that within three years from the date of infringement as noted in Para 16 of the plaint, the suit was filed. Therefore, the suit which was filed for declaration on 21-81990, in our view, cannot be held to be barred by limitation.”
