Reversing the lower court, a state appeals court rejected hedge fund founder John Paulson’s motion to have oral arguments over efforts to dismiss his wife’s billion-dollar lawsuit against him closed to the public.

In a ruling focused on courtroom access, the Appellate Division, First Department set out both procedural and substantive grounds for deciding that Paulson, a billionaire who accumulated immense wealth by betting against subprime mortgages during the 2008 global financial crisis, shouldn’t be able to have the oral arguments kept behind closed doors in Manhattan Supreme Court.
