Jumping case refers to a legal term where a judge or court changes the precedent set by a previous case, essentially "jumping" over it. Synonyms for jumping case include "overruling," "reversal," "contradiction," and "deviation." These terms all refer to a change in legal precedent that goes against a previously established ruling. A jumping case can occur when a judge wants to differentiate their decision from previous rulings or if new evidence or circumstances have come to light. It's important to note that jumping cases can have significant impacts on future legal cases and can change how laws are interpreted and enforced.
