law: Specific Relief Act, 1963
  42. Injunction to perform negative agreement
  Notwithstanding anything contained in clause (e) of section 41,
  
  where a contract comprises an affirmative agreement to do a certain act,
  
  coupled with a negative agreement, express or implied, not to do a certain act,
  
  the circumstances that the court is unable to compel specific performance of
  
  the affirmative agreement shall not preclude it from granting an injunction to
  
  perform the negative agreement:
  PROVIDED that the plaintiff has not failed to perform
  
  the contract so far as it is binding on him.
