Again Zim, I don't think they're allowed to. The best they can do is put Mike Riley or someone on SSN and say the acting official is personally dissapointed with the decisions made. This isn't a reap what you sow situation, this is about personal accusations not professional/match mistakes.
Their matchday mistakes are propagated by FIFA lagging 80 years behind the modern world; that's why refereeing is in such a bad state.
