From the article:
The Ostergaard and Zilletti families said they first waited to see a bill. Then they asked Young to sign an agreement that, with the roughly $900 paid, she would not make additional claims. Young said she was bothered by that request and the lack of trust she believed it signaled. By Dec. 30, she said, she felt that she had to go to court.
You're busted on a charge of sloppy reading.
What they wanted and what they got were two different things. They were in the wrong so it wasn't up to them to call the shots. They thought so but the court said otherwise.
