5. The court emphasized that when a transaction is procured by fraud, the document itself is void, and possession obtained under such a transaction does not confer rights against the true owner (!) .

6. The burden of proof was on the defendant to establish the proper execution of the sale deed, which they failed to do, especially since the Sub-Registrar was not examined to confirm the execution (!) (!) .

9. The case highlights that a sale based on fraud and misrepresentation, especially involving illiteracy and undue influence, is subject to being declared void, and the affected party is entitled to relief including declaration of nullity and injunctions (!) (!) .
