Presumption as to documents: contents and handwriting are presumed when prosecution tenders documents, unless rebutted. Section 144 prescribes that when a document is produced by a person, seized from their custody or received from abroad and tendered by the prosecution, the court shall, unless the contrary is proved, presume the truth of its contents and that signatures or handwriting are that of the person they purport to be, and shall admit the document in evidence even if not duly stamped provided it is otherwise admissible.
