Final answer:
In tackle football, 'consent' serves as a legal defense for battery during the game as players are presumed to consent to reasonable contact customary to the sport. However, this implied consent does not cover acts that are intentionally harmful and outside the rules of the game.
Step-by-step explanation:
When playing tackle football, consent is a defense to legal liability for battery that happens in the normal course of the game. The act of playing the game involves inherent risks, and by participating, players imply consent to reasonable contact that is a customary part of the game.
This means that actions that are typical and expected in football, like tackling, do not constitute battery because the players have consented to that level of contact. However, this consent does not extend to acts that are outside the rules and spirit of the game, such as intentionally harmful behavior that goes beyond the normal interactions on the field.
