Based on the provided legal document, here are the key points regarding the case Nand Kishore Mehra v. Sushila Mehra:

• Core Legal Question: The primary issue was whether the prohibition imposed by Section 4 of the Benami Transactions (Prohibition) Act, 1988, against filing suits or taking defenses applies to benami transactions where property is purchased by a person in the name of his wife or unmarried daughter. (!) (!) (!)
• Statutory Framework: Section 4 prohibits suits or claims to enforce rights in benami property, but Section 3(2) creates an exception for purchases in the name of a wife or unmarried daughter, presuming the property was for their benefit unless proved otherwise. (!) (!) (!) (!)
• Judicial Reasoning: The Supreme Court reasoned that if the Act permits a person to purchase property in the name of their wife or daughter (via Section 3(2)), it cannot simultaneously prohibit them from enforcing those rights via suit or defense under Section 4. To hold otherwise would create a contradiction where rights are created but cannot be enforced. (!) (!)
• Burden of Proof: While the husband is allowed to file a suit or take a defense regarding such property, the statutory presumption in Section 3(2) means he must prove that the property was not purchased for the benefit of the wife or daughter to succeed in his claim. (!) (!)
• Procedural History: The plaintiff (husband) filed a suit in the Delhi High Court seeking relief regarding properties allegedly purchased in his wife's name. The Single Judge rejected the defendant's application to reject the plaint. The Division Bench reversed this, allowing the rejection of the plaint. The Supreme Court allowed the husband's appeal against this Division Bench order. (!) (!) (!)
• Final Ruling: The Supreme Court held that neither filing a suit nor taking a defense is prohibited for present or past transactions involving purchase of property by a person in the name of his wife or unmarried daughter. The appeal was allowed, the Division Bench order was set aside, and the suit was remitted to the Delhi High Court for disposal according to law. (!) (!) (!)
