Now that the U.S. Supreme Court has ruled that bond purchasers can try to revive antitrust claims over alleged manipulation of the Libor interest rate, other key Libor plaintiffs are urging a judge not to leave them on the sidelines.

Susman Godfrey's William Carmody made the plea on Friday to U.S. District Judge Naomi Reice Buchwald, who's presiding over consolidated Libor litigation. In a letter, Carmody asked Buchwald to allow his clients pursue an immediate appeal of her 2013 decision to toss the antitrust claims at the heart of the case.

The letter came just days after Justice Ruth Bader Ginsburg, writing for a unanimous Supreme Court on Jan. 21, ruled that a different group of investors couldn't be forced to wait to appeal Buchwald's decision.
