Background
Overview
This concept is fundamental to understanding the legislative distribution of powers between the Union and States in India's quasi-federal structure, including mechanisms for Union encroachment on state subjects and the historical complexities of applying constitutional provisions to states with special status like J&K.
Article 249 of the Indian Constitution empowers the Parliament to legislate on a subject enumerated in the State List if the Rajya Sabha declares by a resolution supported by not less than two-thirds of the members present and voting that it is necessary or expedient in the national interest to do so. Historically, the application of such constitutional provisions, including Article 249, to states like Jammu & Kashmir was governed by specific presidential orders under Article 370, reflecting the unique federal arrangements and the state's special status.
