(iii) In complex economic matters, every decision is necessarily empiric and it is based on experimentation or what one may call ‘trial and error method and therefore, its validity cannot be tested on any rigid ‘a priori’ considerations or on the application of any strait-jacket formula. The Court must while adjudicating the constitutional validity of an executive decision relating to economic matters grant a certain measure of freedom or ‘play in the joints’ to the executive. The same is required to be given unless such decision is patently, arbitrary, discriminatory and malafide. [ State of M.P. and others v.
