That’s how these election challenges are handled this late in the season. I had one last week were we were served with the complaint in the morning and the hearing was set for 6:00 p.m. that night. Appeals are also super expedited with no time for a formal written opinion. Usually you receive an affirmed or reversed ruling without comment with a more detailed opinion to follow in the next weeks or months. The big issue in every late season election challenge is that ballots must be printed in time for the election. For some jurisdictions, the deadline for sending ballots to the printer for the November election has already passed. You also have to remember that some larger metropolitan areas may have a thousand different types of ballots which include school districts, fire districts, etc. A change to a statewide issue requires a lot of reformatting. I don’t know about the merits of the Florida decision, but the timing and method of delivery is not unusual.
