Linguistic rights
The constitution of India was first drafted on January 26, 1950. It is estimated that there are about 1500 languages in India. Article 343–345 declared that the official languages of India for communication with centre will be Hindi and English. There are 22 official languages identified by constitution. Article 345 states that "the Legislature of a state may by law adopt any one or more of the languages in use in the State or Hindi as the language or languages to be used for all or any of the official purposes of that State: Provided that, until the Legislature of the State otherwise provides by law, the English language shall continue to be used for those official purposes within the State for which it was being used immediately before the commencement of this Constitution".
Languages with official status in India
The Indian constitution draws a distinction between the language to be used in Parliamentary proceedings, and the language in which laws are to be made. Parliamentary business, according to the Constitution, may be conducted in either Hindi or English. The use of English in parliamentary proceedings was to be phased out at the end of fifteen years unless Parliament chose to extend its use, which Parliament did through the Official Languages Act, 1963. In addition, the constitution permits a person who is unable to express themselves in either Hindi or English to, with the permission of the Speaker of the relevant House, address the House in their mother tongue.
