A Court Ex Parte Order is a decision the Court makes only after one party presents evidence. At times it is usually based on an emergency and it would require an Affidavit and a hearing in front of the Judge to determine whether it would occur. Then there would be an immediate order and allow without prejudice and then allowing both parties to be present in a short period of time. It is not typical though, there needs to be extreme circumstances before a Court would likely hear evidence from only one party, but it does occur.
