A priest can be laicized, barred from celebrating public Mass, hearing confessions, sent to a monastery to repent his crimes, excommunicated, etc. He can also be given over to the civil authority for prosecution. Many priests died as a result. Remember the Holy Inquisition, of blessed memory -- we just discussed it?
A priest cannot be made non-priest any more than you can be made un-baptized.
Your confusion is probably lack of familiarity with technical terms and the irreversible character of the sacrament of the Holy Orders. If you really need to understand it, ask.
