judicial lawmaking

Judicial lawmaking refers to the process by which courts create law through their decisions. In common-law systems, this is primarily done through the principle of stare decisis, meaning "to stand by decided matters." This involves judges following earlier rulings, known as precedents, to ensure uniform and predictable justice. When faced with new situations or ambiguities in existing laws, courts interpret these laws and, in doing so, establish new rules that guide future cases.1

While civil-law systems theoretically rely solely on legislative enactments, courts in these systems also interpret vague provisions and fill gaps in legislation, influencing legal outcomes. In the United States, the Supreme Court has broad power to formulate and amend rules of procedure for federal courts, a form of more explicit judicial legislation. However, courts are generally expected to avoid usurping the role of legislatures, as they are not subject to the same democratic accountability.12
