I agree with Lion, calcu losing doesnt really change anything, since he could've won or lost if coaching didnt happen, the problem is that you can't know since yeah, it did happen. Even a void would be biased at this point.
This could've been a win for us though, a void would mean that our chance to score a win was thrown away just 'cause they coached. On the suspension part, I honestly have no idea, since the language barrier excuse has no meaning for me, it's the council's decision. The first natural action should be to fix the result of the match, if there was a murder attempt, what would be the first concern, the well being of the victim or the punishment of the criminal?
