The sanction will be upheld-- appeals court judges are judges, and don't like to see lawyers accuse judges of "treason" or falsely accuse judges of unethical behavior (Orly accused Judge Land of secretly meeting with Attorney General Holder to talk about the case, on a day when Holder was actually in Los Angeles).
And even if the sanction were reversed, that would not "allow the reopening of the Obama legitimacy issue." Only Captain Rhodes has standing to appeal that part of the order, and she didn't.
