The U.S. Senate confirmed University of Pennsylvania Law School professor Stephanos Bibas for a seat on the U.S. Court of Appeals for the Third Circuit on Thursday.

The vote was 53-43, with four members not voting.

President Donald Trump nominated Bibas in June.

Bibas teaches law and criminology and directs the law school's Supreme Court Clinic.

“We are incredibly proud that Stephanos Bibas has been confirmed to serve on the Third Circuit,” the law school's dean, Ted Ruger, said in a news release Thursday. “He possesses all the skills to excel on the federal bench: he is a deeply insightful legal scholar, an accomplished appellate advocate, and an outstanding teacher. The Third Circuit will be adding an exceptional jurist to its ranks.”

The law school released a bio of Bibas, saying that in a 2010 Supreme Court case, Padilla v. Kentucky, Bibas and his co-counsel successfully persuaded the court that noncitizen defendants had the right to accurate information about deportation before they plead guilty.

According to a press release from the law school, “the American Bar Association's Standing Committee on the Federal Judiciary unanimously rated Bibas 'well qualified' as a judicial nominee, their highest ranking.”

The law school said Bibas is the son of a Greek immigrant. His father immigrated to the United States from Greece in 1959 and became a citizen in 1962. His mother is the daughter and granddaughter of Greek immigrants.

Bibas has served as an assistant U.S. attorney for the Southern District of New York, where he prosecuted narcotics, robbery, fraud and other cases.

He received a bachelor's degree from Columbia University in 1989, a B.A. from the University of Oxford in 1991, a law degree from Yale Law School in 1994, and an honorary master's degree from Oxford in 1998. Following his graduation from Yale Law, he served as a law clerk to Judge Patrick Higginbotham of the Fifth Circuit and Justice Anthony Kennedy of the Supreme Court.
