STATE OF KARNATAKA vs N. MUDDAPPA .

The Supreme Court upheld the validity of the Karnataka Motor Vehicles Taxation (Amendment) Act 14 of 1989, specifically sub-section (4) of Section 3, which imposes a special additional tax on motor vehicles carrying passengers or goods in excess of their permitted capacity. The Court clarified that the State Government has the authority to levy such taxes under the provisions of the Motor Vehicles Act, 1939, and distinguished the case from Automobile Transport (Rajasthan) Ltd. v. State of Rajasthan, affirming the State's competence to enact the amendment. The appeal was allowed, reversing the High Court's decision that had declared the tax invalid.
