I recalled that case, in partricular. The damning thing was, she failed to cite any precedents for her decision; it was merely a matter of "her opinion".
As I recollect, the same criticism was made of several of her other reversed decisions.
I practiced law for several decades in the Northeast. We really expected a LOT more from our judges, even the political hacks, than their personal prejudices. Usually a decision starts with the judge's renditions of factual findings, then citations to the decisions in similar matters by courts which had ruled on the legal matters in contention, and then the ruling.
For short: Facts, reasoning, conclusion. She skipped the reasoning part and went straight to the conclusion. She is an embarrassment and, for other reasons, Elena Kagan is worse.
