Protection of States from invasion and violence.
119. The Commonwealth shall protect every State against invasion466 and, on the application of the Executive Government of the State, against domestic violence467.
UNITED STATES.—The United States … shall protect [every State] against invasion; and, on application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic violence.—Art. IV., sec. 4.HISTORICAL NOTE.—In the Commonwealth Bill of 1891, and in the Adelaide draft of 1897, this clause appeared verbatim. At the Melbourne session, Mr. Gordon moved to substitute “attack” for “invasion,” to make it clear that a naval attack was included. This was negatived. (Conv. Deb., Melb., pp. 691–2.)
