It was argued that because Hindi is the national language and is understood by a large number of people in the country, directions should be given to publish all such details in Hindi. His counsel placed reliance on the deliberations in the Constituent Assembly in his arguments. Even the Centre's counsel referred to the Standard of Weights and Measures (Packaged Commodities) Rules and told the court that such declaration on packets should be either in English or in Hindi in Devanagari script.
But the court asked whether there was any notification saying Hindi is India's national language, for it's an ``official language'' of this country. No notification ever issued by the government could be produced before the court in this regard. This is because the Constitution has given Hindi the status of the official language and not the national language.
The court concluded that the rules have specific provisions for manufacturers that particulars of declaration should be in Hindi in Devanagari script or in English, and it's their prerogative to use English. Therefore, no mandamus can be issued on manufacturers or governments for giving details or particulars of package in Hindi.
