Janata Party chief Subramaniam Swamy filed a petition in Supreme Court asking the Apex Court to order the government to declare Ram Sethu a national monument as it was a matter of faith.
Swamy had alleged that Transport Minister Baalu's family members had business interests in both fishing and shipping sectors, and the building of a shorter sea route around India's southern peninsula would greatly benefit them.
Later in 2013 Tamil Nadu government has urged the Supreme Court to direct the central government not to proceed with the implementation of the Project.
The state government said that shipping channel project was not in public interest.
