Language in State Legislature

The Constitution has declared the official language(s) of the state or Hindi or English, to be the languages for transacting business in the state legislature. However, the presiding officer can permit a member to address the House in his mother-tongue. The state legislature is authorised to decide whether to continue or discontinue English as a floor language after the completion of fifteen years from the commencement of the Constitution (i.e., from 1965). In case of Himachal Pradesh, Manipur, Meghalaya and Tripura, this time limit is

twenty-five years and that of Arunachal Pradesh, Goa and Mizoram, it is forty years.
