State ex rel. Secretary, Department for Children and Families

Summary

The Kansas Supreme Court reversed the Court of Appeals' decision that had altered residential custody to the father, holding that the appellate panel improperly reweighed the evidence and should have remanded for a new district‑court determination. The Court affirmed the proper standard of review—light most favorable to the prevailing party—and clarified that appellate courts may not substitute their own factual judgments or order custody changes absent a new finding of material change.
