Jerry, if - after taking over - Judge Lynn reviewed Judge Sanders' rulings and found the inconsistencies that you hypothesised, then she might have decided she needed more time to evaluate these and delayed the trial to May 15.
However, if such inconsistences existed, then both IDCC and E would have known about them much earlier and lobbied for a change. So, in all likelihood, she would have known about these issues before she reconfirmed the Feb. 10 trial date.
In a roundabout way, I'm saying that I don't believe inconsistent rulings are the reason for removing Judge Sanders. JMO, JK
