Party chief Vaiko charged the ruling AIADMK with having intentions of "removing" the entire memorial and therefore it had moved the court against its unveiling, he said.
The Madurai Bench of Madras High Court had given the go ahead for the inauguration of the memorial which was unveiled on November 6 by World Tamil Confederation President and noted pro-Tamil leader P Nedumaran.
Meanwhile, CPI state unit secretary D Pandian appealed for the release of Nedumaran and others, arrested yesterday when they staged a protest without proper permission.
Officials demolished the compound wall of the Mullivaikkal memorial and removed the park, alleging that they were constructed on encroached highway land.
Smaller pro-Tamil outfits including RSYF held protests against India's participation in Commonwealth Heads of Government (CHOGM) Meeting in Sri Lanka.
