What is the definition of omission in a legal context?

In a legal context, omission refers to the failure to act when there is a legal duty to do so. This can occur in various situations, such as when an individual is legally obligated to respond to a victim in need or to adhere to specific legal requirements that necessitate action. The concept of omission is significant in criminal law, where an individual may be held liable for not taking action despite having the responsibility to prevent harm or avert a crime. For example, a lifeguard who neglects to rescue a drowning swimmer may be considered to have committed an omission, as their role creates a duty to act in that scenario. Understanding omission is crucial for grasping the nuances of liability and responsibility in various legal frameworks.
