Uh...I'll take a swing at that one.
Maybe because ... it's the truth?
Just some back ground infomation for ALL:
If an attorney appears on behalf of a client for a case they must file a "notice of appearance". This is the official document that says this attorney is assuming responsibility for representing this client. This is true of ALL attorneys on the case, not just the lead attorney.
(even attorneys who are just standing in are required to file an appearance document.)
Now the real question here is whether this "notice of appearnace" appears in the case. This would be discernable via the federal PACER system of the clerks or just via FINDLAW.COM.
As for the help being crucial, it just depends on the attorney. If Mr. Jean was a new attorney or relativly inexperienced on appeal, then even small details would be "crucial". This includes items like answer any one question to the entire bench. Do not look down.
I want to know more about the nature of the participation.
I also want to know WHY was this law firm involved in homosexual agenda politics?
