If you read the decision of the Illinois Ballot Commission you will see that it quite extraordinarily brief, a couple of sentences, after the finding that standing existed on three points. What is even more unusual, so far as its value as any kind of precedent, it does not cite a single piece of authority and consists of a mere unsupported conclusion. As precedent in would worthless in an actual court. The Illinois law indicates that an appeal lies directly from its decisions to the Clerk of the County Court and from there there lie several layers of appeal, including ultimately to the SCOTUS. Whether Joyce will take an appeal is not clear.
Joyce said he is not taking an appeal. I did read the decision. It is simply summary, as in “summarily executed” without addressing arguments of innocence.
