Two Person Rule Law and Legal Definition

Two person rule is a system designed to prohibit access by an individual to nuclear weapons and certain designated components. This is enforced by requiring the presence of atleast two authorized persons who are capable of detecting incorrect or unauthorized procedures with respect to the task to be performed. Each person will be present during any operation that affords access to sensitive weapons. Two person rule is considered as an additional security measure. It ensures that no single person will have access to nuclear or chemical weapons. This is also known as two man rule.
