Quote: RFL "The decision on whether a player should be charged with On Field Misconduct resulting from a professional match is made by the RFL's Match Review Panel.
Any cases requiring a hearing are heard by the independent Operational Rules Tribunal which is made up of a legally qualified Chair (a serving or retired Judge) and the side members are ex-professional players

What you're saying is roughly what happens now, the only difference is that contesting a ban comes after the decision to ban you has effectively been made, making it difficult to get overturned as it would show that the panel got it wrong.
The system was made to speed up the process as much as anything else.
There could be 50+ incidents a week to look at and the charge/no charge decision is taken first.
It works fine unless your players are charged or opposing players are not charged.
