Answer and Explanation:
Temporary Restraining Order:
Temporary Restraining Order abbreviated as 'TRO' is generally issued in situations demanding immediate action. Courts usually issue TROs on the basis of affidavit from those people or person whose interest needs to be protected or can be harmed. These TROs are issued so urgently that sometimes they do not even provide a chance for the other party to respond.
Preliminary Injunction:
Unlike Temporary Restraining Orders, Preliminary Injunctions can't be carried further without providing the opportunity to the other side to be heard and respond. Generally, Preliminary Injunctions are summoned only after the other party has its say on it or we can say that these are usually issued only after complete trial or after the default or consent of the other party.
