Fabio refused to give Dean Lister his Black Belt and so one of Fabio's newly promoted black belt students (a good friend of Deans) ended up giving it to Dean. Then Fabio proceeded to kick this particular black belt out of his academy for doing so.
That's the short story.....in general i'm sure Fabio is very knowledgable. But the secrecy and tight lips surrounding the Dean Lister charade is quite funny. Anybody that knows of the situation will look down on Fabio for his behavior in this matter. IMO Fabio is Gracie Jiu Jitsu politics at it's worst/best.
Dean had competed for years and won everything, including Abu Dhabi absolute, and was KOK champ, AND beat black belts on a regular basis. Yet Fabio felt that he wanted to keep Dean down. Not sure why, but it sure seems that way.
