When Rules outrun the Statute

This note by J the app examines the decision of the Telangana High Court in BirlaNu Limited v. Union of India & Others (W.P. No. 14564 of 2024), which addresses a foundational issue under the GST framework concerning the limits of delegated legislation. The case arose from audit proceedings seeking to penalise delayed distribution of Input Tax Credit by an Input Service Distributor on the basis of Rule 39(1)(a) of the CGST Rules, 2017. At its core, the judgment interrogates whether, prior to 1 April 2025, the rule-making authority was empowered to prescribe a mandatory time limit for ITC distribution when the parent statute authorised only the prescription of the “manner” of such distribution. The ruling assumes significance not merely for the petitioner, but for the broader constitutional discipline governing GST rule-making and the protection of vested ITC rights.
