Final answer:
Once play has resumed, referees typically cannot change a penalty decision in most team sports due to the rules that provide structure and consistency for the game. Referees may consult with other officials before the game continues if there is immediate uncertainty. The rules established by the sport's governing body determine how penalties should be handled.
Step-by-step explanation:
In sports, particularly in a team sport context like hockey or football, rules dictate that once play has resumed, a referee generally cannot change a decision regarding an assessed penalty. This ensures the game's flow is maintained and that decisions are final to provide structure and consistency within the game. However, a referee may confer with other officials to ensure the correct application of the rules if there is an immediate uncertainty, but traditionally there is no provision for changing a penalty once play has resumed.
The sport's governing body often outlines the rules and regulations regarding the conduct of the referees, including when and how penalties can be assessed, changed, or overturned. These are typically found in the official rulebook or guide that is specific to the sport in question. In some cases, video replay technology can be used to assist officials in making the correct call, but this often occurs before the game continues.
