Preliminary Injunction
A preliminary injunction is a fast, provisional court decision that immediately prohibits or requires someone to act in a certain way. It is often issued within days because a normal proceeding would take too long.
A court proceeding can take months or years. Sometimes that’s too long, because by the time a verdict is reached, damage has occurred that can no longer be undone. For such cases there is the preliminary injunction: a fast, provisional decision by the court. It prohibits one side from a certain behavior or obligates it to do something, until the dispute is properly resolved. The application can be decided within a few days, in urgent cases even within hours. Nothing is finally decided by this, because the actual proceeding follows only later.
When speed decides over the damage
The point lies in the time pressure. An example: A newspaper wants to publish a text tomorrow that contains false claims about a person. Once the text is out, it is copied and spread within seconds. A verdict two years later then hardly helps anymore. The preliminary injunction steps in while intervening can still change something.
In the tech and business world, it is often about large sums of money. A company can thereby achieve that a competitor is not allowed to sell a product for the time being. A sales ban over a Christmas season can hurt more than a late fine. That is exactly why this tool is so popular in patent disputes and competition law.
The downside: because it has to happen quickly, the court examines things less thoroughly than usual. Sometimes the other side is not even heard beforehand. Whoever obtains an injunction that later turns out to be unjustified must compensate for the damage caused. So the proceeding is also a risk for the applicant.
From application to service
At the start there is an application to the court. In it, one must make two things plausible. First: one actually has a claim to have the disputed behavior prohibited. Second: the matter is urgent, a normal proceeding would come too late. In practice, there is often a deadline of about one month after learning of the incident, for the urgency requirement. Whoever waits longer thereby shows that it was not so urgent after all.
The evidence does not need to be complete. It is enough that the account is probably accurate, for example through screenshots or a written affidavit. Lawyers speak of prima facie showing as opposed to full proof. That explains why some injunctions are later overturned again.
The injunction only becomes effective once it is served on the other side. After that, a violation risks a fine that can quickly reach five figures. The affected party can file an objection, after which the matter is reexamined in an oral hearing. It is important to distinguish this from a cease-and-desist letter: that comes from the other side itself and is merely a demand. Only the court turns it into a binding order.
AI models, training data, and product bans
The term regularly appears in tech news. Music publishers and image agencies are taking action against AI providers because their works are said to have been used for training without permission. One goal then is that a model may not be offered further for the time being. Data protection disputes over chatbots are also being fought this way.
A second area concerns hardware patents. Whoever holds a patent on a chip or a wireless connection can try to have the sale of a smartphone or a console stopped. Such news moves stock prices, because a sales ban directly hits revenue.
A common misconception in headlines: a preliminary injunction is not a verdict and not a finding of guilt. It only says that something should be suspended until clarified. Anyone reading a report should therefore pay attention to whether it concerns a provisional order or a final decision. The difference is significant, even if the headlines sound similar.
