regard to the same. Referring to Section 36 of the Stamp Act, Mr.N.Suresh contends that once a document has been marked, then it is not open to the other party to question the document on the ground that it is insufficiently stamped. As regards Section 17 of the Registration Act and inadmissibility of the document, Mr.N.Suresh would invite my attention to the proviso to Section 49, which enables the Court to look into the document for establishing a collateral transaction. Mr.N.Suresh, in support of his submissions, has relied on the decisions of the Hon'ble Supreme Court in Sirikonda Madhava Rao vs N.Hemalatha & others, in SLP(C)No.1488214883 of 2022 dated 14.11.2022; Ramratan (Dead) through legal representatives Vs. Ramkalai Bai and others, in Civil Appeal No.3593 of 2025 dated 04.03.2025; Bondar Singh and others Vs. Nihal Singh and others , reported in AIR 2003 Supreme Court 1905 and Bipin Shantilal Panchal Vs. State of Gujarat , reported in CDJ 2001 SC 119. Relying on the above decisions, Mr.N.Suresh, learned counsel contends that the proper procedure would be to mark the document and decide the admissibility of the document at the time of final hearing. According to Mr.N.Suresh, learned counsel for the revision petitioner, the trial Court has not followed the said procedure and therefore, the order has to necessarily go.
