Yes. Given they have a conviction rate of nearly 100% and there are only two types of trials ("You admit guilt" and "You plead not guilty but then are found guilty and face a harsher punishment for annoying the judge") I strongly doubt the ruling of court matters.
If you convict everyone, some of the are bound to be guilty (which is what you said) but that neglects those that a) not guilty or b) who are guilty, but do not deserve death (which seems to be some sort of default choice one way or the other in the EoB).
