However, in reply, learned counsel for the petitioners points out that, in paragraph no.6 of the plaint, the plaintiffs/opposite parties have specifically referred to a suit, in which a similar written statement had already been filed in the year 2016, mentioning about the agreement of 1980. In order to bye-pass the fact of having acquired knowledge of the agreement in 2016 itself, the plaintiffs/opposite parties adopted the oblique method of permitting the previous suit to be dismissed for default and to file the present suit without taking out any challenge to the 1980 agreement. As such, as on September 23, 2020, when the amendment application in the current suit was filed, the relief already stood time-barred, since the date of knowledge attributable to the plaintiffs had to be taken at least from the year 2016. Since the limitation for challenging a document is three years, such belated introduction of the said relief was patently time-barred.
