President Obama’s four recent appointees to the U.S. Court of Appeals for the District of Columbia Circuit have had extensive careers in U.S. Supreme Court appeals and civil rights cases. However, their backgrounds offer very limited insight into their approach on environmental law.

Anthony Cavender, senior counsel in Pillsbury’s Houston-based environmental law practice, noted that all D.C. Circuit judges have to worry about the integrity of the court, and the four new judges are expected to share that concern.

“There's a circuit culture that they all adhere to,” Cavender said. “Longstanding institutions like that, almost like the Catholic Church, absorb a lot of people, and after all, they are judges, and they're supposed to look at the law.”
