The resolution was adopted unanimously after members spoke on the appropriateness of renaming Madras High Court as Tamil Nadu High Court.
"Naming the High Court of Judicature at Madras as Tamil Nadu High Court will be most appropriate," Jayalalithaa said, moving the resolution.
"This House urges the Union government to alter the name from Chennai HC, proposed in the Bill introduced in Parliament to Tamil Nadu HC," the resolution said, adding "It will be correct to call the High Court as Tamil Nadu High Court which is presently being called as Madras High Court."

Listing out the historical reasons behind the name of Madras High Court, Jayalalithaa said the British Parliament had enacted the Indian High Courts Act, 1861 and Letters Patent was granted by Queen Victoria under which the Madras High Court was established in 1862.
The High Courts established after states were reorganised on linguistic basis in 1956 were named after such states. Thus, it was "not appropriate" to call Madras High Court under the same name that was set up on the basis of Letters Patent granted by Queen Victoria, she said.
A proposal was sent to the Central government in 1997 to rename Madras High Court as Chennai High Court after Madras city was renamed as Chennai in 1996, the CM added.
