Happy to address the question, but it's not clear to me exactly what the question is. In the example I provided the lower court and court above it shared jurisdiction over the case by law. Generally, upper courts for case load reasons will not hear a case that's not an appeal. In this case, the higher court considered hearing the case based on the arguments of the other party, but I won based on my arguments that as a result of the contract between the parties the lower court was explicitly the only court that had jurisdiction over the matter. For what it's worth, I'm not an attorney, just skilled at legal matters and litigation; as an example, once had a judge issue an order by phone for me and have their clerk draft the order too - ask any attorney if they've ever done that... :-)
