The correct answer is Ireland. Explanation & Key Takeaways: • The concept of Directive Principles of State Policy (DPSP) in the Indian Constitution has been borrowed from the Constitution of Ireland, which was enacted in 1937. • DPSPs are enshrined in Part IV of the Indian Constitution, spanning from Articles 36 to 51. • These principles are non-justiciable in nature, meaning they are not enforceable by any court but are considered fundamental in the governance of the country. • The DPSPs aim to create a welfare state by ensuring socio-economic justice and guiding the state to take affirmative action for the betterment of society. • They serve as a guiding framework for the government to formulate laws and policies that align with the principles of justice, equity, and liberty. • The Irish Constitution influenced the framers of the Indian Constitution because Ireland faced similar challenges as a newly independent state when it adopted these principles. • Examples of key provisions in DPSPs include promoting equal justice, ensuring free legal aid, organizing village panchayats, providing the right to work, and improving public health.
