I'm pretty sure the publishers are alleging that a crime has been committed. In that case, private parties can't open a suit (at least if Swedish criminal law is at all similar to Norwegian law), so this asks the police to open a criminal investigation into the matter. What happens next in the Norwegian system at least is that the police will conduct their investigation, and at some point when the police consider their investigations complete the prosecutor's office will decide what to do next. Next steps can be concluding that no crime has occured, to ask the police to investigate further, that a crime has been committed but the evidence are insufficient for a trial, or that someone should be tried.

It's not going to be a lawsuit. You don't sue companies for breaking the law in Sweden. It's going to be a criminal case if police deem so.

Fraud is a crime. When a crime is committed citizens inform the police to investigate.

If someone punches you in the street or steals your wallet will you file a lawsuit or call the police? Maybe in America is different, but the normal thing to do is to go to the police. Fraud is not different, the police will investigate.

Fraud is usually a crime and therefore a matter for the police, even in the US.

I know nothing about Swedish law, but in the US, there can be both civil and criminal fraud. They might be planning to file a lawsuit also.

In Sweden, you can charge someone/something two ways.

Either you and a company has a disagreement and you sue one or the other and it goes to court.

But in this case, ”Utgivarna” which are basically a company/org that represents a lot of media outlets, basically went to the police instead and said ”hey, we think that meta is breaking the Swedish law”.

What the police does is that they then investigate and then finds out who is responsible for the company (Mr. Zuck) and then eventually will indict him. Since its Meta that is breaking the law and The Zuck is the one in charge of Meta.
