Swamy obtained Supreme Court Stay against the implementation of Sethusamudram Shipping Canal Project (SSCP). He believes that it would hurt the sentiments of people who believe that this shallow land connecting between Tamil Nadu and Sri Lanka was built by Lord Rama. He strongly opposes the implementation of SSCP citing that implementing this scheme will be a criminal offence under section 295 Indian Penal Code. He wrote letters to Prime Minister of India in June 2009 asking him to stop the project and had informed the Supreme Court on 14 October 2015 that the government may not continue with the Sethusamudram Project.
