  title, not specifically enforceable
  (1) A contract to sell or let any immovable property cannot be
  
  specifically enforced in favor of a vendor or lessor-
  (a) who, knowing not to have any title to the
  
  property, has contracted to sell or let the property;
  (b) who, though he entered into the contract
  
  believing that he had a good title to the property, cannot at the time fixed by
  
  the parties or by the court for the completion of the sale or letting, give the
  
  purchaser or lessee a title free from reasonable doubt.
  (2) The provisions of sub-section (1) shall also apply as far as
