Supreme Court Justice Ruth Bader Ginsburg will miss oral arguments for the first time today as she recovers from surgery.

The Hill reports:

Supreme Court Spokeswoman Kathy Arberg said Ginsburg is working from home after undergoing surgery on Dec. 21 to remove two cancerous nodules in the lower lobe of her left lung, which were discovered incidentally during tests performed at the George Washington University hospital to diagnose and treat rib fractures she sustained in a fall on Nov. 7. Arberg said Ginsburg will participate in the cases using briefs, filings and transcripts of oral argument

It has yet to be determined when the Supreme Court justice will return to the court.

The Supreme Court will be hearing arguments on two cases today: “a battle over the preemption federal and state laws and…over whether fair debt collection laws apply to nonjudicial foreclosures, which do not require a court’s approval.”
