The simple answer: They can't.
The courts are by definition, and necessity, have to be impartial. They can not support either side.
What probably happened is that her lawyer met with their lawyers. They hashed out an offer. Her lawyers, probably deep in the red, realistically, advised her to take the offer or this can go on buried in paperwork for years - if any settlement at all, ever. She was probably going to have to appear in court every couple of weeks for years. I've been there. It is very personally/emotional exhausting. They count on that too.
They both agreed to terms. They write a one page court order mutually requesting that the case be dismissed. Judge asks if they both agree - if yes, it is over in the court. Nothing that the judge or courts can do about it. The court never even gets a copy of the settlement documents.
The WT is well aware that everything in court is a matter of public record. All transcripts, and filed papers, can be requested by a FOIA (freedom of information act) request by anyone. They did not want more in the records - and her shut up.. So they probably paid extra to silence the case.
It happens everyday. Individuals vs. big insurance companies. Pay a little extra "hush" money - hide all the details so they don't look bad, and no one can use the case in the future cases. Sworn statements in a court case can be used as evidence in other cases. Big technology companies steel patents from small ones because they have more money and can outlast small companies.
Once two parties reach a settlement they request to drop the cases. The settlement can really include anything. Most Judges know what's going on, but there is nothing they can do about it.
I hate it too. But you can reliably say that she obviously was paid off to sweep it under the rug.
