Going into the panel, he knew that the best he hope for if found guilty was 3 games. He pleaded guilty and got 4 games, which isn't a bad result.
I think appealing this decision shows a complete lack of integrity and remorse by both Bousquet and Catalans. I believe a 4 game ban was lenient, to then appeal that ruling is a disgrace.
The appeal can't even be about guilt and wanting the ban removed, as he's already said he is guilty!
