In In re Marriage of Eben-King & King (2000) 80 Cal.App.4th 92, the court defined the standard of review that an appellate court is to apply in reviewing an order denying a motion to set aside under Code of Civil Procedure section 473.
"The standard for appellate review of an order denying a motion to set aside under section 473 is quite limited. A ruling on such a motion rests within the sound discretion of the trial court, and will not be disturbed on appeal in the absence of a clear showing of abuse of discretion, resulting in injury sufficiently grave as to amount to a manifest miscarriage of justice. Where a trial court has discretionary power to decide an issue, an appellate court is not authorized to substitute its judgment of the correct result for the decision of the trial court. '"'The appropriate test for abuse of discretion is whether the trial court exceeded the bounds of reason. When two or more inferences can reasonably be deduced from the facts, the reviewing court has no authority to substitute its decision for that of the trial court.'" ' " The burden is on the complaining party to establish abuse of discretion, and the showing on appeal is insufficient if it presents a state of facts which simply affords an opportunity for a difference of opinion. " (King, supra, at p. 118.)
