Examine the philosophical focus and judicial enforceability distinguishing Part III from Part IV of the Indian Constitution:
1. The overarching intent of the Directive Principles is to advance the collective socio-economic welfare of the community as a whole.
2. The overarching intent of Fundamental Rights is to secure and guarantee distinct political and civil liberties for the individual.
3. The judicial branch possesses the explicit constitutional authority to declare any parliamentary statute unconstitutional if it directly violates a Directive Principle.
