revise and repeal provisions related to the athletic commission.

SB 64 revises and clarifies definitions for combat sports in South Dakota, specifically updating terms related to boxing, kickboxing, and mixed martial arts. It adds precise definitions for participants (e.g., "boxer," "mixed martial artist"), roles (e.g., "promoter," "manager"), and events (e.g., "competition," "sparring exhibition"). The bill amends existing law to confirm the South Dakota Athletic Commission’s authority to regulate these sports, including licensing, enforcing safety standards, and reporting event results. It directly affects the commission, athletes, promoters, and event organizers by clarifying the regulatory framework for combat sports events in the state. This is a procedural update to definitions and commission duties, not a substantive policy change.
