Article 347 of CoI : Article 347: Special provision relating to language spoken by a section of the population of a State.

Explanation using Example

Example 1:

In the state of Maharashtra, a significant portion of the population in a particular district speaks Konkani. The residents of this district collectively submit a petition to the President of India, requesting that Konkani be recognized as an official language in their district. After reviewing the petition and confirming that a substantial proportion of the population desires this change, the President directs the state government to officially recognize Konkani for administrative purposes in that district. As a result, government offices in the district start providing forms and conducting official business in Konkani, in addition to Marathi and Hindi.

Example 2:

In the state of Karnataka, a large community of people in a specific region speaks Tulu. The community leaders gather support and formally request the President to recognize Tulu as an official language in their region. The President, upon being satisfied with the substantial demand, issues a directive to the Karnataka state government to recognize Tulu as an official language in that region. Consequently, schools in the region begin offering Tulu as a medium of instruction, and local government services are made available in Tulu, ensuring that the community can access public services in their native language.
