Lay magistrates are part-time judges who preside over minor criminal cases in lower courts. They come from all walks of life and do not require legal qualifications. The document provides an overview of the roles and responsibilities of magistrates, the types of cases they handle, and the qualifications being sought for new magistrates. It encourages readers to apply if they have good character, communication skills, maturity, and can commit to hearing at least 26 cases per year on a voluntary basis.
