Language of the plaint in Uttar Pradesh

Article 350 of the Constitution of India says thus:

350  Every person shall be entitled to submit a representation for the redress of  any grievance to any officer or authority of the Union or a State in any of the languages used in the Union or in the State, as the case may be.

If English is in use in the particular place you can give in English. Besides English is the language of law in India under the Constitution. For the purpose of practicability and convenience local language was allowed in courts lower than the High Courts even during the British period. An expert on Hindu Scriptures has to know Samskrit. An expert on Indian law or rather every qualified legal person in India should know English. If any matter from a lower court goes on, say, appeal to a High Court or any matter such a writ is directly filed in a High Court has to be in English only. If the lower court judgment is in a language other than English, an authentic English translation has to be provided. This is law.
