Which part of the Constitution of India declares the ideal of Welfare State?
(a) Directive Principles of State Policy (b) Fundamental Rights (c) Preamble
Almost every key says that the answer is (a). I differ from this. This is because of the use of the term "Ideal".
Ideal indicates values (ought to be). These values are declared in Preamble and not in DPSP. What is given is DPSP are sort of operating principles/guidelines for implementing the constitution.
To substantiate further, Ideals of welfare state means "policy goals" of the welfare state - ie. eco & soc justice, liberty etc. DPSP contains the "policies tools" for fulfilling these goals.
Therefore, the ideal of welfare state is declared in Preamble and not in DPSP. I hope it makes sense.
