A Miami federal judge on Thursday disqualified former state appellate Judge Angel Cortiñas from representing the Miccosukee tribe and its attorneys at a sanctions hearing.

The sanctions request flows from the tribe’s dismissed racketeering lawsuit against its former longtime lawyers Dexter Lehtinen, Guy Lewis and Michael Tein, among others. They alleged the tribe’s current attorney, Bernardo Roman III, filed the lawsuit knowing it contained false allegations.
