Interesting that this story has stirred up so much contention.
I imagine the law was on the side of the child in this case, and she took advantage of that. I haven't read every article on this so I don't know all sides.. but I do have reasonable faith in our justice system (most of the time); sometimes a judge's hands are tied because of a legal technicality.
However, having read so many stories on these boards about parents who are trying to set boundaries for their adult children, and having dealt with some of it myself, the bottom line for me was the precedent it sets for kids suing their parents when they don't get what they want. I think of the parents who have to go through a formal eviction process to get their "deadbeat" kid out of the hous. Kids today are entitled enough, without a judge adding fuel to that fire.
It's also a shame that grandparents would support their grandchild in suing their parents - what message are they sending? That makes me saddest of all, I think.
