She had missed a round of oral arguments in January, the first time she had been absent from them since her appointment to the court in 1993.
Ginsburg, 85, who had been working from home since being released from the hospital on Dec. 25, returned to the court on Friday for meetings with her fellow justices.
Last month, doctors gave her the all-clear, saying that there was “no evidence of remaining disease,” according to the Supreme Court.
On Feb. 4, Ginsburg, known for supporting the arts, attended a production of “Notorious RBG in Song” at the National Museum of Women in the Arts in Washington, marking her first public appearance since the surgery.
Tuesday’s session of oral arguments is for a patent case involving the U.S. Postal Service.
