Understanding the Standard of Review in California Appeals
In appellate law, one of the most important factors influencing the outcome of a case is the standard of review. When a party appeals a decision in California, the appellate court does not retry the case; instead, it reviews how the trial court applied the law. At the Law Offices of James M. Braden, we assist clients across San Francisco in understanding how these standards apply and what they mean for the likelihood of success on appeal.
Each standard of review determines the degree of deference the appellate court affords to the trial court’s decision. Knowing which standard applies is crucial when preparing an appeal, as it shapes the legal arguments and the court’s approach to reviewing the case.
What Is a Standard of Review?
A standard of review defines the legal lens through which an appellate court examines a lower court’s ruling. It determines whether the appellate court should uphold or reverse the decision. Some standards are highly deferential to the trial court, while others allow the appellate court to review the issue independently.
The three primary standards used in California appeals are: de novo review, abuse of discretion, and substantial evidence. Each applies to different types of legal questions, and each carries its strategic considerations.
De Novo Review
De novo review applies when the issue on appeal involves a question of law, such as interpreting a statute or applying legal principles. Under this standard, the appellate court does not give any deference to the trial court’s ruling. Instead, it reviews the issue from scratch and reaches its conclusion.
This standard provides appellants with the best opportunity to have the ruling overturned, but it only applies when the appeal is based solely on questions of law. Examples include rulings on contract interpretation, jurisdiction, or constitutional challenges. If your appeal hinges on one of these issues, a San Francisco appeal attorney can evaluate whether de novo review may apply.
Abuse of Discretion
When the trial court has significant leeway in making its decision, such as in granting or denying motions, the abuse of discretion standard is used. Here, the appellate court will only reverse the ruling if it finds that the trial judge made a decision that was arbitrary, irrational, or beyond the bounds of reason.
This standard applies in matters like evidentiary rulings, discovery sanctions, or requests for continuances. While it is harder to overturn a decision under this standard, it is not impossible. We regularly assist clients in determining whether the trial court misused its discretion and in framing that issue for appeal.

Substantial Evidence Review
This standard is used when a factual finding by the trial court is challenged. Under a substantial evidence review, the appellate court examines the record to determine whether there is enough evidence to support the trial court’s decision. It does not reweigh evidence or reassess credibility.
This is a highly deferential standard. Even if the appellate court would have reached a different conclusion, it will affirm the ruling as long as there is some reasonable basis in the record. To present a viable argument under this standard, an experienced San Francisco appellate law attorney will identify gaps in the evidence or highlight where legal thresholds were not met.
Why It Matters in Your Appeal
The standard of review may determine the outcome of your appeal before your arguments are even made. It shapes how the court approaches the issues and what kind of legal reasoning is persuasive. If your appeal is based on legal interpretation, your chances may be higher than if it rests on factual disputes.
