concert of action
- The idea used in tort law that holds all individuals responsible who performed wrongful acts contributing to someone's injury, despite only one person directly causing the injury
- A principle from criminal law that makes a person who assisted or encouraged a criminal act just as accountable for the criminal act as the one who actually committed it
- The court applied the concert of action theory, holding the group liable for the plaintiff's injury even though only one member caused it.
- Under the concert of action rule, a person who provided support for the criminal act was also held responsible.
- Not every participant may have thrown the rock at the window, but under the principle of concert of action, each is liable for the damage.
