Nanda Lal Dhur Biswas vs Jagat Kishore Acharjya Chowdhuri on 17 July, 1916
Before their Lorships consider the circumstances in which that attestation took place, they think it is desirable to emphasise once more that attestation of a deed by itself estops a man from denying nothing whatever excepting that he has witnessed the execution by implication; any knowledge of the contents of the document, and it ought not to be put forward alone for the purpose of establishing that a man consented to the transaction which the document effects. It is, of course, possible, as was pointed out by their Lordships in the case of Banga Chandra Dhur Biswas v. Jagath Kishore Chowdri (1916) 31 M.L.J. 563 : (1916) L.R. 48 I.A. 249 : 4 L.W. 458 L.A.I.R. 1916 P.C. 110, that an attestation may take place in circumstances which would show that the witness did in fact know all the contents of the document, but no such knowledge ought to be inferred from the mere fact of the attestation.
