Under Article 35 of the National Basketball Association (NBA) Constitution, the NBA commissioner has the power to hand down disciplinary actions (either suspension or fines less than $50,000) on players for on-court incidents, conducts that do not conform to standards of fair play, conducts that do not comply to federal or state laws, and conducts that are detrimental to the game of basketball or the league. As defined by the 2005 Collective Bargaining Agreement (CBA) between the National Basketball Players Association (NBPA) and the NBA, any party (a player, a team, the NBA or the NBPA) can appeal to an arbitrator if a suspension is longer than 12 games or a fine is more than $50,000. If an appeal is filed, the arbitrator would have the power to either uphold or reject the decisions made by the commissioner. If the incident is serious enough, such as point shaving or substance abuse, players can be permanently banned from playing, although players banned for substance abuse are permitted to be reinstated two years later under the anti-drug agreement between the league and the NBPA.
