The case in our country is the system of two trials and final adjudication, but the longest I know is that the case has gone through seven trials, that is, seven judgments.
The number of trials depends on the specific circumstances of the case, and there is no fixed number.
There are two kinds of judgment announcements, one is a conventional judgment, and the other is a court judgment. So it is not necessarily pronounced in court, but the verdict is public.
