The judges job is to provide an unbiased and just verdict, but a judge is not superhuman and may make mistakes, just like any other person.
What can decrease the probability of errors?more judges and possibility to appeal for more different pannel of jurors.
For example you have 3 stages of arbitration:
13 jurors - 9-4 u win
13 jurors - 6-7 u loose
13 jurors - 11-2 u win
So it is more informative and decrease the probability of errors
Alo you should check rates of jurors!
