Fine for alleged assault?

Hi, the police just brought a letter from the district court to my friend personally. It's about my brother claiming that my boyfriend choked him and that sort of thing and that left him with injuries, strains and pain for days. However, it was the case that my brother wanted to steal my laptop, my friend stood in his way and my brother just kept walking towards him. My friend then tried every possible means to prevent him from stealing my belongings. (So it was self-defense?)
The letter says that my friend has to pay 1200 euro, but he can also raise an objection and then there will be a main hearing.

I have no idea what we can and should do now. The police have documented my brother's injuries, but it shouldn't have come to this if my brother had just stopped walking towards my friend. Incidentally, my friend also had injuries that lasted for days.

THE POLICE DELIVERED THE LETTER BECAUSE WE HAVE MOVED AND SO THE LETTER IS NOT LOST

We don't know what to do. Do we get right in court if we object? What options do we have?

Hi, the police just brought a letter from the district court to my friend personally.

Of course.

The letter says that my friend has to pay 1200 euro, but he can also raise an objection and then there will be a main hearing.

I have no idea what we can and should do now.

It says in the letter:
Either pay or appeal and wait for the verdict.

Can, however, also raise an objection and then a main hearing will take place.

Did you write? Objection is called negotiation. Taking evidence, pleading, judgment. So either acquittal or judgment.

Hi, such a penalty order is only possible if the facts are clear in order to save legal costs.

The friend can of course file an objection, then there's a court hearing where all sides are heard again and evidence can be presented.

Of course, its outcome is uncertain, since I don't know all the details, I will also be careful not to speculate about it.

If the friend is found guilty, the legal costs will of course be added to the penalty.
