In Sweden there is a additional review board that go through the decision made by the inspector. The idea is to limit the power that a single inspector has. In practice however the review board tend to rubber stamp decisions, so incompetence/malice still happens.

There was a huge mess right after metoo when a inspector went against the courts rulings. The court had given the father sole custody in a extremely messy divorce, and the inspector did not agree with the decision. As a result they remove the child from his father, in direct contrast to the courts decision, and put the child through 6 years of isolation and abuse with no access to school. It took investigative journalists a while, but the result of the case getting highlighted in media was that the inspector and supervisor is now fired, with two additoal workers being under investigation for severe misconduct. Four more workers would be under investigation but too long time has passed. The review board should have prevented this, as should the supervisor for the inspector, but those safety net failed in this case in part because of the cultural environment at the time.
