Is an order on a motion to tax costs appealable?

"California’s appellate courts are divided as to whether an order on a motion to tax costs on appeal is an appealable order."
Today 1/5 sides with the "yes" faction: Williams v. Safire (A132145).


William Safire has absolutely nothing to do with this case, Williams v. Safire.

Also see Williams v. Safire (A133759) ("We dismiss the appeal, as we conclude the order denying appellant’s motion for sanctions is not immediately appealable.")
