Yes Virginia, the Supreme Court Does Matter - A Cat's Paw in the 5th Circuit
Although as an object fact we know that it is important when the Supreme Court issues a decision, see my discussion just above about the importance of a SOX case that will be decided next term, but it never hurts to be reminded.
Although the result might have been the same regardless of Staub, that's not what it sounds like. The case involved two LSU police officers vying for the Chief's job. The male not only got the interim position, but also the ear of the Chancellor. Even though the Chancellor made the decision to select him, not Ms. Haire, the actions of the interim male Chief, were what made the difference, at least according to Judge Jolly who wrote for the majority.
