More than likely what happened is the lawyer for North Star asked for summary judgment on the claims that were addressed, knowing he/she might be able to argue that they are devoid of legal foundation. Whereas the rest of the case is probably on-going and could take a long time to come about. Civil cases can run in to many years, which is a tactic often used by the defense in order to make the plaintiff have to continue to pay attorney fees.
The case may have settled, but the family may also not have wanted to in order to get it on the record that this prison camp is not a treatment center. Costs might not be a serious issue for them as many families who send their kids to these places are upper middle class to upper class. But either way, it is clear the information we have received so far does not tell us the case is over, only what has been ruled upon to date. I say we should just be patient, I am sure more information will be forthcoming.
