What special provision does the President have regarding regional languages in a State?
The special provision relating to language spoken by a section of the population of a State is that on a demand being made in that behalf, the President may, if he is satisfied that a substantial proportion of the population of a State desire the use of any language spoken by them to be recognized by that State, direct that such language shall also be officially recognized throughout that State or any part thereof for such purpose as he may specify.
