Basically:
Madhubala signed a contract and started Naya Daur shooting with Dilip Kumar
When the time came for an outdoor shoting, her father made her walk out.
BR Chopra sued her.
Her father said the suit was instigated by Dilip because she had rejected her.
Dilip Kumar was called as a witness and was cross-examined.
Both sides accused each other.
I believe the money was returned and it was settled out of court. [Please correct me if I am wrong.]
The proceedings as reported in Times of India, Bombay April-May 1957.
