The Indian Constitution has adopted the concept of "Directive Principles of State Policy" from the Constitution of Ireland. The Directive Principles of State Policy are a set of guidelines or principles that direct the government in making laws and policies. These principles are not enforceable by the courts but are considered fundamental in the governance of the country. They aim to establish social, economic, and political justice, promote the welfare of the people, and ensure a just and equitable society. By adopting this concept from the Irish Constitution, India recognized the importance of providing principles for the government to work towards the well-being of its citizens and the overall development of the nation.
