Standards for Granting Provisional Measures in International Court Proceedings
Quick fact
International courts, such as the ICJ and ITLOS, rarely grant provisional measures—they have been requested in hundreds of cases but granted in only a fraction, often reserving them for extreme situations where rights are genuinely at risk of irreparable harm.
Why this is interesting
When a nation takes another to an international court, the case can drag on for years. What if one side is about to build a dam that floods the other's land—or start a military campaign that destroys the very thing being argued over? Courts have a tool to stop the clock: provisional measures.

Understanding Standards for Granting Provisional Measures in International Court Proceedings
Think of provisional measures like a temporary restraining order in domestic law. When you sue someone, you can ask the court to freeze assets or stop certain actions until the trial is over. In international law, courts like the International Court of Justice (ICJ) or the International Tribunal for the Law of the Sea (ITLOS) can issue similar orders to prevent the situation from deteriorating while the case is being decided. But the international context is different: there is no global police force. So courts are cautious. To get provisional measures, a country must meet a set of rigorous standards designed to balance fairness and caution. First, the court must have prima facie jurisdiction—meaning it seems likely the court has authority to hear the case at all. Second, the applicant must prove that the rights they claim to protect are 'plausible'—that is, they actually exist in law and are not just invented. Third, there must be a real and imminent risk of irreparable harm—damage that cannot be undone with money or later judgments, like loss of life, destruction of archives, or pollution that wipes out ecosystems. Finally, the measures must be urgent: waiting for the final judgment would be too late. For example, in the case of Ukraine v. Russia (2017), Ukraine sought provisional measures related to alleged support for terrorism and racial discrimination. The ICJ found that the rights it claimed were plausible and that there was a risk of irreparable harm, ordering Russia to refrain from further violations. This illustrates how the standards work in practice.
A deeper explanation
The mechanism underlying these standards is the courts' need to maintain their own credibility and the integrity of the judicial process. If a court issues provisional measures too easily, it risks prejudging the merits and undermining the authority of its final decision. If it is too strict, aggrieved parties might suffer irreparable harm, making any eventual judgment meaningless. The first criterion, prima facie jurisdiction, is a gatekeeping measure: the court does not need to be certain it has full jurisdiction, but it must be convinced that the case is not manifestly outside its remit. This prevents frivolous applications while still allowing urgent protection. The plausibility test is a low bar: the applicant does not need to prove the rights exist definitively, only that they are credible. This acknowledges that an applicant may not have all the evidence at the preliminary stage. Irreparable harm is the core of the standard. Harm is considered 'irreparable' when it cannot be fully compensated by reparations later. Loss of life, severe environmental damage, destruction of cultural heritage, or creation of irreversible facts on the ground qualify. The court assesses whether the harm is imminent—not speculative—and whether the measures could prevent it. Urgency is closely tied to imminence: the measures must be so urgent that they cannot wait for the full trial. This ensures that provisional measures are only used when truly necessary. These criteria are cumulative: an applicant must satisfy all of them. Courts also weigh the balance of convenience—whether granting or denying the measures would cause more harm to either side during the proceedings. Understanding these standards is crucial for diplomats, lawyers, and scholars because they determine whether a state can obtain immediate protection of its rights and interests, often with significant political consequences. The binding nature of these orders (as confirmed in the LaGrand case) means that even though enforcement relies on political pressure, they carry substantial legal weight.
