Jivarajbhai Ujamshi Sheth And Others vs Chintamanrao Balaji And Others on 19 November, 1963
The Court further held as under: An arbitrator who
acts in manifest disregard of the contract acts without
jurisdiction. His authority is derived from the contract
and is governed by the Arbitration Act which embodies
principles derived from a specialised branch of the law of
agency(see Mustill and Boyds Commercial Arbitration, 2nd
edn., p. 641). He commits misconduct if by his award he
decides matters excluded by the agreement(see Halsburys
Laws of England, Volume II, 4th edn., para 622). A
deliberate departure from contract amounts to not only
manifest disregard of his authority or a misconduct on his
part, but it may tantamount to a mala fide action. A
conscious disregard of the law or the provisions of the
contract from which he has derived his authority vitiates
the award.
