<P> Per Article 37, state and union governments, as duty, shall make further detailed policies and laws for implementation considering DPSPs as fundamental policy . In contrary to Article 37, many policies have been implemented by state and union governments which go against the DPSPs such as using intoxicating drinks as source of major tax revenue instead of implementing prohibition for better health of people, separation of judiciary from executive, uniform civil code for the citizen, etc . When the union government feels that a DPSP is no longer useful to the nation, it shall be deleted from Constitution by bringing a constitutional amendment to remove ambiguity in policy making / direction . Judiciary can repeal any policy / law devised by the government which is diametrically opposite to any DPSP . </P> <P> An existing policy in line with DPSP cannot be reversed, however it can be expanded further in line with DPSP . The policy changes applicable under DPSP shall not be reversible unless the applicable DPSP is deleted by constitutional amendment (ex. prohibition implemented once in a state cannot be repealed later as long as it is part of DPSP) </P> <P> The directive principles ensure that the State shall strive to promote the welfare of the people by securing a social order in which social, economic and political justice is animated / informed in all institutions of life per Article 38 (1). Dr. Ambedkar clarified as given below in the Constituent Assembly debates on Article 38 high lighting its inevitable implementation . </P> <P>... The word' strive' which occurs in the Draft Constitution, in judgement, is very important . We have used it because our intention is even when there are circumstances which prevent the Government, or which stand in the way of the Government giving effect to these Directive Principles, they shall, even under hard and unpropitious circumstances, always strive in the fulfilment of these Directives . That is why we have used the word' strive' . Otherwise, it would be open for any Government to say that the circumstances are so bad, that the finances are so inadequate that we cannot even make an effort in the direction in which the Constitution asks us to go . </P>
