AIR 1984 SC 667

You can find the judgment passed in this case at this location - http://www.judis.nic.in/supremecourt/qrydisp.aspx?filename=9599
I personally find the judgment search tool of the Indian courts very very cumbersome.

I tried looking for the judgment in the case of AIR 1973 AP 17 and invariably the page showed - "No matching results"... WTF? Maybe there is a secret trick to finding the hidden pot of gold :)
