Pushing the resolution in the house, the chief minister said Tamils living in Sri Lanka as well as Tamils of Sri Lankan origin living in other countries should take part in the referendum.
"India should stop calling Sri Lanka a friendly nation," she said.
"There should be an international probe on the war crimes during the war (against the Tamil Tigers) and people responsible for that should be tried before an international court," she said.
The resolution also urged the Indian government to impose economic sanctions on the island nation until the "oppression" on Tamils there were stopped.
