M/s Kamdhenu Cattle Feed Industries 1993 (1) SCC 71 and (iii) National Buildings Constructions Corporation Vs. S.P. Singh and Ors. 1998 SCC (l7S) 1770.

The existence of legitimate expectation may have number of different consequences and one of such consequences is that the authority ought not to act to defeat the legitimate expectation..
