Given as they linked the wikipedia article, it seems likely they are aware. Just because she lost on appeal does not detract from the parent's point, which is that clearly these things are not harmless otherwise there probably wouldn't be such a court case.

Almost no healthcare is harmless. Anyone can sue for almost anything, there's a low threshold to bring a case.

She was over 16 at the time, and capacitous, and so she got the treatment that she asked for.
