David Boies has taken over as counsel of record for a pro se litigant at the U.S. Supreme Court from retired Seventh Circuit judge Richard Posner.

The client was the first that Posner took after retiring.

Boies, of Boies Schiller Flexner LLP, is known for taking on high-profile clients, including representing Al Gore in Bush v. Gore and defending movie mogul Harvey Weinstein against a slew of sexual abuse allegations.

Posner agreed to represent William Bond last year in an appeal arguing that a federal district court shouldn’t have denied Bond’s attempt to amend his complaint without justification.

The Fourth Circuit ruled in an unpublished opinion in August that Bond’s appeal didn’t have any merit.

Bond had sued federal officials in Maryland federal court, alleging they violated his First Amendment and due process rights by spying on him in an attempt to cover up “‘provable corruption’ in the Maryland U.S. courthouse.”

“This appeal raises important questions about access to the judicial system for pro se litigants and how a trial court must consider a pro se litigant’s good-faith attempt to cure perceived deficiencies in his complaint,” the brief said.

Bond has a colorful past. He killed his father when he was seventeen, served no prison time, and later married a wealthy heiress. Eventually he divorced and ended up almost destitute.
