Judge blasts Waymo v. Uber lawyers, delays trial until December 9 years ago
Sure but presumably, two judges scheduled events pertaining to the same attorney at the same time.
I took the question to ask more or less, "Is their any judicial obligation to avoid scheduling conflict, when the attorney is already obligated to be present at a different court-related function".
I assume this is usually granted by courtesy, but a fed up judge has no obligation to do so.
