CASE STUDY – 1

Sandeep had sold his house to Bachchan for Rs10 lakh. It was only later that he came to know that it was even conservatively estimated to be worth at least Rs 25 lakh. Immediately there-after, he preferred to back out and refused to perform the contract by giving an undisputed possession of his house to Bachchan, on the plea that the sale price was too inadequate, and that he (Bachchan) must pay him Rs15 lakh more, when alone he will sell his house to him. Thereupon, Bachchan filed a suit against Sandeep to perform the valid contract entered into between them. What are the chances of Bachchan winning the case? Give reasons for your answer.
