Scalia was merely citing a fact regarding Supreme Court procedure. Any Justice can bring a case to conference, but to get a hearing before the High Court, a petitioner needs four of them to agree that the issues deserve a hearing. It relates to each and every case brought to the court.
The story, as told by Ms. Taitz, indicates that she identified herself to Justice Scalia, as an attorney that had a case pending judicial review. There is NO WAY that I believe Scalia would speak to the woman, in any way and however vaguely, about that specific case. No way. I think that this is a clear indictment of Ms. Taitz's credibility.
The Canon of Ethics regarding Ex Parte communication is crystal clear. Justice Scalia would not commit a violation as overt as this, either intentionally or not.
