The appellants moved the High Court under Art. 226 of the Constitution challenging the validity of the Act. The High Court by its judgment and order dated 6/06/1955, dismissed the writ petitions. Thereupon, the appellants obtained the certificates that the cases involved substantial questions of law as to the interpretation of the Constitution. The petitions under Art. 32 of the Constitution were moved in this Court for the same purpose of challenging the vires of the Act. The appellants and the petitioners will, in the course of this judgment, be referred to, for the sake of convenience, as the appellants. The State of Assam, the Commissioner of Taxes, appointed under S. 6 of the Act, and the Superintendent of Taxes are the respondents to the appeals and the writ petitions.

( 2 ) IT appears that the appellants are growers of tea in West Bengal or in Assam and carry their tea to the market in Calcutta from where the tea is sold for consumption in the country or is exported for sale out of the country. The sale of tea inside Assam bears a very small proportion to the tea produced and manufactured by the appellants. Thus the bulk of tea produced and manufactured is carried out of Assam, either for internal consumption in India or for export abroad. Besides the tea carried by rail, a large quantity of tea is carried by road or by inland waterways from Assam to Bengal and in some of these cases, from one part of West Bengal to another part of the same State through inland waterways, only a few miles of which pass through the territory of the State of Assam. The Assam Legislature passed the act which received the assent of the Governor of Assam on 9/04/1954, the came into force on and from 1/06/1954. The purpose of the Act is to levy taxes on certain goods carried by road or inland water-ways in the State of Assam.

The appellants in some of the cases, in pursuance of demand notices, submitted returns to the third respondent, the Superintendent of Taxes, in the prescribed form in respect of tea despatched and carried up to 30/09/1954, under protest. They also paid the tax demanded under protest. The appellants moved the High Court of Judicature in Assam under Art. 226 of the Constitution challenging the validity of the said Act and praying for the issue of a writ of mandamus directing the respondents to forbear from giving effect to be provisions of the Act and the notification issued under the Act and/or a writ of prohibition or any other appropriate writ restraining them from taking steps under the provisions of the Act. The appellants challenged the validity of the Act mainly on the grounds that (1) the Act, rules and the notifications under the Act were ultra vires the Constitution, because the Act was repugnant to the provisions of Art. 301 of the Constitution as the tax on carriage of tea through the State of Assam had the effect of interfering with the freedom of trade, commerce and intercourse; (2) that tea being a controlled industry under the provisions of the Tea Act, 29 of 1953, the Un
