The US State Department has asked a court in NewYork to dismiss a lawsuit filed by a Sikh rights group for declaring RSS as a "terror group" saying it has no standing.
In an 18-page motion filed Tuesday before judge Laura Taylor Swain of the Southern District of New York, US attorney Preet Bharara said Sikhs For Justice (SFJ) lacks standing to bring such claims.
Even if SFJ had standing, the political question doctrine bars judicial review where the Secretary of State has not designated an organization, it said.
"Neither SFJ nor this Court possesses authority to compel the Secretary to designate an entity as a foreign terrorist organization-a discretionary action that implicates important foreign affairs and national security considerations, and which is entrusted to the political branches," the motion added.
SFJ has filed a lawsuit in the US court to label the Rashtriya Swayamsevak Sangh as a foreign terrorist organization.
It accuses RSS of "believing in and practicing a fascist ideology and for running a passionate, vicious and violent campaign to turn India into a 'Hindu' nation with a homogeneous religious and cultural identity".
"Political question doctrine cannot trump the fundamental human rights of protection of life and liberty which are embedded in the American constitution," SFJ attorney Gurpatwant S Pannun said.
SFJ will challenge the US Government's bid to block the labelling of RSS as "terror group", he said.
A senior Libyan official accused supporters of the late Libyan leader Muammar Gaddafi of carrying out an attack that killed the U.S. ambassador to Libya and three other Americans in Benghazi.
Deputy Interior Minister Wanis al-Sharif told a news conference in Benghazi that the attackers had used rocket-propelled grenades.
"There were RPGs...which shows there were forces exploiting this. They are remnants of the (former) regime," he said. The news conference was broadcast on Al Jazeera television.
He suggested that the attackers could have been acting in revenge for the extradition from Mauritania this month of Gaddafi's former intelligence chief Abdullah al-Senoussi.
Gaddafi was ousted by rebel forces backed by NATO air power in August 2011 and was killed in October after months as a fugitive.
