certified copy which is sought to be taken on record is seen, it would indicate that it nowhere has the thumb impressions/the signatures of Shiv Bux. The said document is a certified copy and this in itself is merely at best a proof to say that Mahadev along with Shiv Bux had executed a document in favour of Shri Ganga Ram. Thus, this document in itself cannot be used to compare the signatures / the thumb impressions of Shiv Bux. Moreover, it is urged that the signatures/ the thumb impressions would be on the original document which would be with Ganga Ram the vendee and there has been no effort made by the defendants to have got the same summoned. The suit has been pending since the year 1983 and more than 40 years have lapsed. The sale deed has been brought on record only in the year 2018 without explaining the delay. Moreover, the said sale deed has no relevance to the controversy as once the defendants have missed the boat, they can not be permitted to patch the lacunae for their case by introducing additional evidence which necessarily entails recording of evidence which shall further retard the disposal of the instant appeal by several months and in the aforesaid circumstances the said document is neither relevant nor sufficient ground has been shown by the appellants within the four corners of Order 41, Rule 27 C.P.C.. Hence the application deserves to be dismissed.
