The big discrimination case before the Supreme Court

In last year's Supreme Court sleeper case, a woman named Lily Ledbetter lost her right to sue because she didn't go to court the first time her paycheck was docked because of sex discrimination, as opposed to when she later realized she was being shortchanged. On Wednesday, the Supreme Court will hear a new employment discrimination case that could also shake up the law of the land and leave the court's liberal dissenters apoplectic. This one may not only prune back employees' rights under the particular statute at issue, but also help the Supreme Court's conservatives rein in discrimination suits more generally."
