Negligence means that a person acted in a way that puts others in harm’s way.
In the case of a personal injury lawsuit, the defendant failed to behave with the level of care that any person of good judgment would exercise in the same situation.
While negligence usually translates to actions that the defendant committed, a defendant can also be accused of negligence by omission.
Omission occurs when a person has a duty to act but fails to do so.
