The Legal Definition of Usurpation
The dictionary definition is very similar to the definition of the crime of usurpation had in law dictionaries:
The illegal encroachment or assumption of the use of authority, power, or property properly belonging to another; the interruption or disturbance of an individual in his or her right or possession. (West’s Encyclopedia of American Law, edition 2)
I sure hope John Charlton and Leo Donofrio continue to collaborate—we desperately need them both.
