Above the Ombudsmen are appeals courts where lower courts decisions can be reviewed, after which is Final Appeal, which, in serious cases may be heard by the Senate Appeal Board. Babylon 5 had at least two Ombudsmen: Wellington and Zimmerman. There was an unnamed female Ombuds - who presided over G'Kar's trial - who may or may not have been Zimmerman. It is unclear if Babylon 5 continued to have an Ombudsmen after breaking away from the Earth Alliance.
