I'll agree with you that Tribunal needs some serious work to help ensure case accuracy, but this idea isn't it.
At the moment I still feel no compulsion to work tribunal cases with how things stand. I view cases with reports containing racial / homophobic / national slurs, hatred fueled insults at fellow players (not friendly banter at all), and I hit Punish. Surprise surprise, cases are being pardoned.
Simply not worth it. I'll look forward to trying again once Tribunal undergoes its next major overhaul. The current version is a waste of my time.
