Can you really blame Justices Thomas, Roberts, Alito and Scaila?
Of course those Justices have the power to remove Obama from office, they must fear that Obama during the duration of the case at the SCOTUS would use his assets at the CIA to neutralize the Justices.
No, they don't.
It takes a majority of the House and two thirds of the Senate. The Supreme Court's only involvement is to send the Chief Justice to preside over the Senate deliberations while wearing extra fancy robes.
