 The formula was formulated in response to demands from non-Hindi speaking states of the South, such as Karnataka, Andhra Pradesh, and mainly Tamil Nadu.Currently, the three language system is not followed in Tamil Nadu due to efforts of former Chief Minister C. N. Annadurai.The first recommendation for a three-language policy was made by the University Education Commission in 1948–49, which did not find the requirement to study three languages to be an extravagance, citing the precedents of other multilingual nations such as Belgium and Switzerland.
