I am reading 'Indian Polity' by M Laxmikanth, chapter on 'Directive Principles of State Policy'.
Please explain the following Stanza with help of an example
"The Supreme court has ruled many a times that in determining the constitutionality of any law,if a court finds that the law in question seeks to give effect to a Directive Principle,it may consider such law to be 'reasonable' in relation to Article 14(equlaity before law) or Article 19(six freedoms) and thus save such law from unconstitutionality "
