Art. 31(C) envisages that certain directive principles can hold sway over the fundamental rights and are binding upon the state. It says notwithstanding anything contained in Art. 13 no law giving effect to the policy of the state towards securing certain directives shall be deemed to be void on the ground that it is inconsistent with or takes away or abridges any of the rights conferred.
Now directives which the parliament considers imperative to be implemented can be imposed like the right to education has been brought from directive to the fundamental rights and thus has become binding on the state.
