The Centre has opposed a Public Interest Litigation (PIL) in the Delhi High Court seeking to classify air purifiers as medical devices and reduce their Goods and Services Tax (GST) from 18% to 5%. The government argues that the GST Council is the sole constitutional body empowered to decide tax rates and that judicial intervention would violate the separation of powers. It also contends that classifying air purifiers as medical devices would impose additional regulatory burdens, potentially restricting market supply and creating monopolistic conditions.
