Hailed as one of the strongest domestic violence policies in major sport, MLB’s policy has no minimum or maximum penalties. The policy gives the “joint policy board” broad latitude in imposing requirements and Commissioner Rob Manfred has already demonstrated some willingness to impose punishments without findings in criminal or civil court.
The NBA’s current collective bargaining agreement requires a minimum 10-game suspension for any violent felony (not just violence against women). Like many leagues with general/vague policies, the NBA has faced criticism for inconsistent enforcement and penalties.
The National Hockey League has faced criticism for both vague policies and inconsistent penalties. As of 2014, the league’s domestic violence prevention efforts were just part of the “substance abuse and behavioral health program” included in the CBA.
The National Football League has faced a great deal of negative press regarding their inadequate responses in major domestic violence cases. While the NFL has improved their policies, many critics point to continued concerns about enforcement.
A code of conduct for all England footballers does exist, but it is not publicly available, nor is it an enforceable policy. It is instead a set of “recommendations.” English football has seen several recent cases of criminal sexual assault in recent years.
