Discuss the historical trajectory of the Three-Language Formula in India and the recurring Centre-State tensions it has generated.

Article 343 made Hindi the Union's official language while allowing English to continue for fifteen years [1]. The Three-Language Formula emerged from this compromise as a device to reconcile national integration, regional linguistic identity and administrative pragmatism — but its trajectory shows a settlement repeatedly deferred rather than achieved.

Historical trajectory

• 1950 — constitutional design: Article 343 fixed Hindi in Devanagari as official language with English as an additional medium for a transitional period; the Eighth Schedule separately recognised (today) 22 languages, excluding English [1].
• 1963 — statutory extension: the Official Languages Act, 1963 (effective 26 January 1965) permitted English's continued official use beyond the fifteen-year sunset, responding to non-Hindi states' resistance [2].
• 1968 — the formula proper: the National Policy on Education, 1968 enunciated the formula — Hindi, English and a modern Indian language in Hindi states; the regional language, Hindi and English elsewhere [3].
• 2020 — revival: NEP 2020 reformulated it with greater flexibility and a mother-tongue medium in early grades, while retaining the requirement that two of three languages be native to India [4].
• 2026 — litigation: CBSE's circular making three languages compulsory from Class 9 is under challenge; the Supreme Court has questioned classifying English as "non-indigenous" [5].

Recurring Centre-State tensions

• Asymmetric burden: non-Hindi states effectively study three languages while Hindi states seldom implement the third Indian language — the formula's chief equity grievance [3].
• Federal competence: education is a Concurrent List subject, so central curricular design collides with state autonomy; Tamil Nadu has retained a two-language policy since the 1965 anti-Hindi agitations [1].
• Definitional friction: treating English as "foreign" despite its entrenchment in governance, courts and higher education is now itself a constitutional question [5].

The formula's history suggests that linguistic pluralism is better served by persuasion than prescription. A flexible, consultative framework — letting states choose combinations while the Centre funds teacher supply — would honour both Article 351's promotive spirit and cooperative federalism.
