A ruling’s reach depends on how broadly a court frames its legal principle

Evidence

A judicial ruling imposes legal obligations on the parties to the case and on lower court judges, who must apply the legal principles enunciated by the court in future cases. Judicial rulings also have legal implications for a broader “target population” that is in the same situation as the parties to the case. The size of this target population depends on the breadth of the legal principles a court announces, which in turn depends to a considerable extent on the breadth of the enactment the court is interpreting. Constitutional provisions, for example, tend to be more broadly applicable than statutes or administrative regulations. To some extent, however, courts themselves may determine the legal implications of their rulings by choosing the legal principles on which they will base their decisions. — G.
