Indian Contract Act, 1872
200. Ratification of unauthorized act
cannot injure third person
An act done by one person on behalf of another, without such
other person's authority, which, if done with authority would have the effect
of subjecting a third person to damages, or of terminating any right to
interest of a third person cannot, by ratification, be made to have such
effect.
Illustrations
(a) A, not being authorized thereto by B, demands, on behalf of
B, the delivery of a chattel, the property of B, from C who is in possession of
it. This demand cannot be ratified by B, so as to make C liable for damages for
his refusal to deliver.
(b) A holds a lease from B, terminable on three months' notice.
C, an unauthorized person, gives notice of termination to A. The notice cannot
be ratified by B, so as to be binding on A.
