Micah judges Magic stuff in an unofficial capacity. Each event he judges also does not require a judge for any reason.
He will not be permitted to play in any event he officially judges.
Besides, we're talking about 40k here. Magic, fortunately, has definitive rules that can almost always be stated easily. Assuming players are playing correctly and know / understand the rules, Magic has very, very, very, very, very few "judgement calls."
40k is not that way. There are grey areas and plenty of areas where a disagreement can arise (line of sight, for one... scenarios for two)
