What the Evidence Shows
The claim that millions of people are discovering they can become magistrate judges in many states without being licensed lawyers is supported by multiple sources, with some important nuances:
1. State-Level Magistrate Judges: Several states, including South Carolina, allow magistrate judges to serve without requiring a law degree or bar admission. These magistrates typically handle lower-level cases such as small claims, traffic violations, or preliminary hearings. NPR and ProPublica highlight South Carolina as a notable example where magistrates often lack formal legal training but still make decisions affecting many people.npr.orgnpr.orgSouth Carolina Magistrate Judges Don't Need Law Degrees To Handle Lower-Level...

In summary, while the statement is broadly accurate for many state-level magistrate judgeships, it does not apply to federal magistrate judges or most higher court judgeships. The scope of authority and responsibilities of non-lawyer magistrates is generally limited compared to lawyer-judge roles.
