The Power of a Federal Prosecutor

Looking for expert answers to this question. If a State district judge makes a ruling in a civil case. Does a Federal Attorney have the right to violate or ignore that district courts ruling without having to appeal or have some type of court hearing to overturn the previous ruling of the District court?

It does not seem reasonable to me that if a District court order has no relevance from the day the case is decided, what is the purpose of even have a District court trial? Just for the attorneys to make money? I am not buying that. I know the attorneys are there to make money but I do believe that a court order is intended to be complied to until an different determines it is not. I do not believe that AUSA Kevin VanderSchel in his position as Assistant Prosecuting Attorney for the Southern District of Iowa has any power to simply ignore a court order as he advised me he did. I think he is knowingly making false statements. Someone show me a document that gives that power to an attorney. I do not have any reason to believe one word that comes from the mouth of any government official. Hearsay is not evidence, even the common citizen knows that.
