A temporary restraining order (TRO) and a preliminary injunction are both provisional remedies that direct a party to refrain from (or, in a mandatory form, to perform) a particular act, in order to preserve the status quo and prevent irreparable injury while a case is pending, but they differ in duration and procedure. A TRO is an emergency, short-lived order issued to prevent grave and irreparable injury during the brief period before the court can hear the application for a preliminary injunction. Under the Rules of Court, a TRO issued by a Regional Trial Court (or a first-level court) is effective for only twenty (20) days from service on the party sought to be enjoined, and this period is non-extendible; within that period, the court must conduct a summary hearing to determine whether the preliminary injunction should be granted. In cases of extreme urgency, the executive judge (or the presiding judge) may issue a 72-hour TRO ex parte, which the court must then, within the 72 hours, hear and determine whether to extend it to the full 20 days. TROs issued by the Court of Appeals are effective for sixty (60) days, and those by the Supreme Court until further orders. A preliminary injunction, by contrast, is issued after a hearing (with notice and the opportunity to oppose) upon a showing of the requisites, and it lasts during the pendency of the action, until the case is decided or the injunction is dissolved. The requisites for both, especially the preliminary injunction, are: a clear and unmistakable right (a right in esse) of the applicant; a material and substantial invasion of that right; and an urgent necessity to prevent serious and irreparable damage. A bond is generally required to answer for the damages the enjoined party may suffer if the injunction is later found to be wrongfully issued. So a TRO is a brief emergency order (20 days in the trial court, non-extendible, or 72 hours ex parte) to hold matters until the injunction hearing, while a preliminary injunction, issued after a hearing, lasts through the case, and both require a clear right and the threat of irreparable injury, plus a bond.
Both Preserve the Status Quo
A TRO and a preliminary injunction both direct a party to refrain from (or do) an act to preserve the status quo and prevent irreparable injury during a case — but they differ in duration and procedure.
The TRO: Short and Emergency
A TRO is short-lived: in the RTC, effective only 20 days from service (non-extendible), within which the court hears the injunction application. In extreme urgency, a 72-hour ex parte TRO may issue. CA TROs last 60 days; SC TROs until further orders.
The Preliminary Injunction: Lasts the Case
A preliminary injunction is issued after a hearing and lasts during the case. Both require a clear right (in esse), a substantial invasion of it, and urgent necessity to prevent irreparable damage, plus a bond.
Practical Takeaways
- TRO = brief emergency order (20 days RTC, or 72 hours ex parte);
- Preliminary injunction = after a hearing, lasts through the case;
- Both need a clear right + irreparable injury and a bond.
Frequently Asked Questions

What are the requirements for a preliminary injunction? A clear and unmistakable right of the applicant (a right in esse), a material and substantial invasion of that right, and an urgent necessity to prevent serious and irreparable damage. A bond is generally required.
Is a bond required for an injunction? Yes, generally. A bond is required to answer for the damages the enjoined party may suffer if it is later determined that the applicant was not entitled to the injunction.
