The Supreme Court observed that the conviction under Section 498-A IPC would not be sustainable when the marriage was found to be null and void.
In this case, the accused were convicted for the offences punishable under Section 498-A IPC and Sections 3 and 4 of the Dowry Prohibition Act. In appeal before the Apex Court, it was contended that, as the marriage between the parties has been held to be null and void by the judgment of the High Court of Madras, the conviction under Section 498-A IPC would not be sustainable. Reliance was placed on the decision in Shivcharan Lal Verma v. State of Madhya Pradesh (2007) 15 SCC 369.
