An order denying a motion to vacate judgment under CCP 663 is a separately appealable order even if the issues raised on that appeal overlap issues that the appellant could have or did raise on an appeal from the underlying judgment.  Clemmer v. Hartford Insurance Co. (1978) 22 Cal.3d 865 should not be read to hold to the contrary, as a long line of California Supreme Court authority stretching back to Bond v. United Railroads (1911) 159 Cal. 270, 273 has held that orders denying motions to vacate under section 663 are appealable.  The issue was not squarely addressed in Clemmer, which did not cite any authority on the point or purport to overrule prior Supreme Court authority on the point.
