Appendix A (Judge Classes)
Head Judge, Floor Judge, Level 1 Judge
Level 1 - Local Judge
Level 1s are generally Local judges, who oversee local tournaments, run Regular REL premiere events, or aid in larger premiere tournaments. They usually operate in a metro-area. They are knowledgeable of Magic rules, DCI tournament rules, structures, formats, and are capable of organizing store-level events.
Local Judges are the main envoys to the retail community and work with (sometime for) retailers. Retailers often inquire about local judges and will often have local judges asked to aid them in organizing and running/reporting their tournaments. Many retailer operators employ local judges or become local judges themselves.
