conclusion that the left thumb mark appearing on the Will was not that of the Puttavenkatamma. He further submits that evidence obtained under Section 45 of the Evidence Act 1872, is only an opinion and the same would not form substantial evidence unless corroborated with other evidence. He further submits that the plaintiff therefore, had examined attesting witnesses to the Will, in compliance to Section 63 of Indian Succession Act 1925 and Section 68 of Evidence Act. Thus it is his submission, the Trial Court without taking note of the other material evidence, erred in relying upon a selective evidence with regard to the proof of left thumb mark of the deceased and accordingly has come to the erroneous conclusion which is confirmed by the First Appellate Court resulting in perversity in the judgment, giving rise to substantial question of law requiring for consideration, at the hands of this Court.
