Legal Question in Constitutional Law in Illinois

Re: appeal

You ask about "instances like this", but "like this" is a very hard concept to define. Cases which are very much like each other in some ways are often very different in others, so what you mean by "like this" may be differ from what someone else -- even someone familiar with the case -- would think it means.

In any event, it seems your son has already won a victory on appeal and that at least one ruling by the trial court has been reversed. This does not necessarily mean that he has won the case, though. The fact that some evidence must be excluded does not mean *all* the evidence has to be kept out; there may be other evidence which remains available and which might be enough to support a conviction.

There is really no way anyone unfamiliar with your son's case can offer you any kind of meaningful answer to your question. I presume that your son already has an attorney working for him. She is the one you should talk to if you want more information.
