Case Note & Summary
The petitioners, Aegis Logistics Limited and another, filed a writ petition under Article 226 of the Constitution of India challenging Rule 18 of the Factors and Categories of Users of Buildings or Lands (Assignment of Weightages by Multiplication) Fixation of Capital Value Rules, 2010, framed by the Municipal Commissioner of the Brihanmumbai Municipal Corporation (BMC) in purported exercise of powers under sub-section 1(B) of Section 154 of the Mumbai Municipal Corporation Act, 1888. The petitioners contended that Rule 18 exceeded the limits of authority conferred by the enabling provision, as Section 154(1B) only permitted the Commissioner to assign weightages for determining capital value of properties for property tax purposes, but Rule 18 imposed additional tax liability not authorized by the Act. The court noted that the said Rules were revised in 2015 and Rule 18 had been deleted, but the challenge remained relevant for the period when it was in force. The court examined the scope of Section 154(1B) and found that it empowered the Commissioner to frame rules only for assigning weightages to factors and categories of users for the purpose of determining capital value, and not to create new heads of taxation or impose additional burdens. The court held that Rule 18 was ultra vires the enabling provision as it went beyond the delegated authority. The court also referred to the decision in State of Tamil Nadu & Anr vs P. Krishnamurthy & Ors. (2006) 4 SCC 517, which laid down the grounds for challenging subordinate legislation, including failure to conform to the statute under which it is made or exceeding the limits of authority conferred by the enabling Act. The court allowed the petition and quashed Rule 18, holding that the Commissioner had exceeded his powers.
