Official language requirement preserves English as authoritative for proceedings and statutory texts unless law provides otherwise. The article presumes English as the authoritative official language for all proceedings in the Supreme Court and every High Court and for the authoritative texts of Bills, Acts, Ordinances and orders, rules, regulations and bye laws until Parliament provides otherwise. The Governor may, with the President's prior consent, authorise use of Hindi or another State official language in High Court proceedings (excluding judgments), and where a State prescribes a non English language for legislative texts the English translation published under the Governor's authority in the Official Gazette is deemed the authoritative English text.
