Case Note & Summary
This case arose from a reference made by the President of India under Article 143(1) of the Constitution concerning the legislative competence of the State of Gujarat to enact the Gujarat Gas (Regulation of Transmission, Supply and Distribution) Act, 2001. The Act aimed to regulate the transmission, supply, and distribution of gas, defined as a matter in gaseous state predominantly consisting of methane. The core issue was whether natural gas, including Liquefied Natural Gas (LNG), was a Union subject under Entry 53 of List I or a State subject under Entry 25 of List II of the Seventh Schedule of the Constitution. The Union contended that natural gas is included within the definition of petroleum and petroleum products, thus falling under its exclusive legislative domain. The State of Gujarat argued that the term 'gas' in Entry 25 encompasses all types of gases, including natural gas, and that it had the authority to legislate on this matter. The court analyzed various legislative practices and definitions, concluding that natural gas is indeed a petroleum product and that the Gujarat Act encroached upon the Union's legislative powers. The court emphasized the need for harmonization between conflicting entries in the legislative lists and ultimately held that the Gujarat Act was unconstitutional as it exceeded the State's legislative competence. The court's decision reinforced the principle that in cases of overlapping legislative powers, the Union's authority prevails.
