These motions have a very low success rate and this particular motion likely has an even lower likelihood of success. Jackson is a respected and experience judge. I actually was taken aback by a couple of her comments about the case but courts of appeal are extremely reluctant to force such recusals.
The Stone team seems particularly aggrieved that Jackson said that the jury in the case had "served with integrity."
There is a pending motion for a new trial based on the alleged bias of the foreperson of the jury and the defense feels that the comment prejudges the merits of that motion.
I happen to agree that Stone deserves a new trial if these allegations are true. I have a column appearing in today Hill newspaper calling for such a new trial. An appellate court would like view such a statement as virtually rote for judges and not a commitment on the outcome of the pending motion.
