The decision
in Guwahati Carbon Limited (7 supra) indicates that there can be
other circumstances where Writ Petition can be entertained not
withstanding the existence of an alternative remedy.
In Harbanslal
Sahnia v. Indian Oil Corpn. Ltd., the Supreme Court has indicated
other situations where Writ Petition can be entertained even though
there is an alternative remedy by declaring:
7. In an appropriate case, in spite of availability of the
alternative remedy, the High Court may still exercise its writ
jurisdiction in at least three contingencies: (i) where the writ
petition seeks enforcement of any of the fundamental rights; (ii)
where there is failure of principles of natural justice; or (iii)
where the orders or proceedings are wholly without
jurisdiction or the vires of an Act is challenged. (See Whirlpool
