How can the validity of laws giving effect to certain directive principles be ensured, according to article 31C?
According to Article 31C, the validity of laws giving effect to certain directive principles can be ensured by ensuring that they do not violate any rights conferred by Article 14 or Article 19. This is done by including a declaration in the law stating that it is for giving effect to such policies. The law cannot be challenged in court on the grounds that it does not give effect to such policy, provided that where such law is made by the Legislature of a State, it has been reserved for the consideration of the President and has received his assent.
