On the basis of the percentage of the people speaking Tamil, the S.R.Commission recommended for the transfer of four taluks namely, Agasteeswaram, Thovalai, Kalkulam and Vilavancode to Tamil Nadu from the State of Travancore-Cochin. The same yard stick was used for the transfer of Shenkotta Taluk to Tamil Nadu. Even though Shenkotta was fully transferred by the commission, the Joint Committee appointed to fix the exact boundaries of the states, divided Shenkotta Taluk and allowed Travancore–Cochin State to retain a major portion.
