The group has filed a similar human rights violation cases against the Congress party and its leader Sonia Gandhi.
Sikhs for Justice (SFJ) said it decided to subpoena Rahul Gandhi after he said in a televised interview that"some Congress men were probably involved in 1984 anti-Sikh riots and they have been punished for it."
The group said it will subpoena Rahul Gandhi "as a witness before New York federal court in the pending 1984 Sikh rights violation lawsuit."
Reacting to SFJ's demand, eminent Indian-American Ravi Batra said that any requests for subpoena issued on Rahul Gandhi will be responded to with a motion todismiss.
Ravi Batra, who represents the Congress party in US courts, also strongly objected to SFJ's demand saying the group should not build "visitor-suites in their sand castles.
"Staying out of the internal politics of India, but dealing only with the legal issues raised by SFJ's perpetual desire to raise false public expectations -any subpoena issued by SFJ on Rahul Gandhi will be met with a motion to quash," Ravi Batra said.
