Directive Principles [SEP] Implementation
There is no need of any constitutional amendment and simple legislation by the Parliament is adequate to implement the Directive Principles as applicable laws per as they are already enshrined in the constitution. The State has made few efforts till now to implement the Directive Principles. The Programme of Universalisation of Elementary Education and the five-year plans has been accorded the highest priority in order to provide free education to all children up to the age of 14 years. The 86th constitutional amendment of 2002 inserted a new article, Article 21-A, into the Constitution, that seeks to provide free and compulsory education to all children aged 6 to 14 years.
