Non-justiciable but foundational β the Directive Principles that guide how the state is meant to govern.
Part IV of the Constitution (Articles 36-51) contains the Directive Principles of State Policy β guidelines for the state while framing laws and policy. Unlike Fundamental Rights, DPSPs are not enforceable in any court, but Article 37 calls them "fundamental in the governance of the country" and a duty of the State to apply. They were borrowed from the Irish Constitution.
Since DPSPs sometimes require the state to act in ways that could restrict Fundamental Rights, courts had to work out which prevails. In Golaknath (1967), FRs were held to be beyond Parliament's amending power. This was overturned by Kesavananda Bharati (1973), which allowed FRs to be amended, but protected by the "basic structure" doctrine. Minerva Mills (1980) then held that the balance between Fundamental Rights and Directive Principles is itself part of the basic structure β neither can be given absolute primacy over the other.
