You guys are missing a really big key here.
"HS and her parents instructed lawyers to pursue a compensation claim against the principal and the School District in early 2009"
AKA, her parents basically hired a lawyer and tried to sue the school for kicking her off the cheerleading team. While I don't think she deserved to be kicked off the cheerleading team, I sure as hell don't think she should be rewarded with thousands of dollars over it either. Sounds to me like the courts in Texas were simply responding appropriately to another frivolous lawsuit. The 45k in question is for filing a frivolous lawsuit.
Now, with that aside, let's put some of that into perspective. I'm not siding against her, altogether. I don't necessarily agree that she should have been kicked off the cheerleading squad... but more than that, I SURE as hell don't feel that her assailant had any right to be playing for the school basketball team. Sounds like he got off easy on a plea bargain. Go US Justice system.
But with that said, being kicked off the cheerleading squad for refusing to cheer, while circumstantially a bit out of line, is certainly not so out of order that it deserves a lawsuit. The source doesn't say, but I'd like to know what her parents/lawyers were asking in the suit against the school. I'd be willing to bet that it was a stupid amount. Hence, the courts dismissing it as a frivolous lawsuit, and holding her responsible as such.
