How does a judge’s role differ in a civil-law court and a common-law court?

The role of a judge differs significantly between civil-law and common-law systems, primarily regarding their level of involvement in litigation.

Common-Law Tradition

In common-law systems, the procedure is adversarial. The responsibility for gathering and presenting evidence lies with the parties and their lawyers. The judge acts as an impartial arbiter, ensuring the rules of procedure are followed and deciding which party has made the more convincing case. Judges in this tradition are typically appointed or elected from the ranks of experienced legal practitioners rather than following a lifelong judicial career path.12345

Civil-Law Tradition

In civil-law systems, the procedure is inquisitorial. The judge takes an active role in the proceedings, functioning as an investigator responsible for discovering the truth. This includes questioning witnesses, examining documents, and directing the parties to focus on specific factual or legal points. Civil-law judges are typically part of a professional elite who enter the judiciary early in their careers and undergo specialized training.123
