Opened for signature at the Pan American
Union on May 1, 1957
The High Contracting Parties, desirous of clarifying, supplementing, and strengthening the principles and rules stipulated in the Convention on Duties and Rights of States in the Event of Civil Strife, signed at Havana on February 20, 1928,
Have resolved, in order to carry out those purposes, to conclude the following Protocol:
Each Contracting State shall, in areas subject to its jurisdiction:
a) Keep under surveillance the traffic in arms and war material that it has reason to believe is intended for starting, promoting, or supporting civil strife in another American State;
b) Suspend the exportation or importation of any shipment of arms and war material during the period of its investigation of the circumstances relating to the shipment, when it has reason to believe that such arms and war material may be intended for starting, promoting, or supporting civil strife in another American State; and
c) Prohibit the exportation or importation of any shipment of arms and war material intended for starting, promoting, or supporting civil strife in another American State.
The provisions of Article 1 shall cease to be applicable for a Contracting State only when it has recognized the belligerency of the rebels, in which event the rules of neutrality shall be applied.
The term "traffic in arms and war material", which appears in the third paragraph of Article 1 of the Convention on Duties and Rights of States in the Event of Civil Strife as well as in this Protocol, includes land vehicles, vessels, and aircraft of all types, whether civil or military.
The provisions of the Convention on Duties and Rights of States in the Event of Civil Strife with respect to "vessels" are equally applicable to aircraft of all types, whether civil or military.
Each Contracting State shall, in areas subject to its
jurisdiction and within the powers granted by its Constitution, use all appropriate means
to prevent any person, national or alien, from deliberately participating in the
preparation, organization, or carrying out of a military enterprise that has as its
purpose the starting, promoting or supporting of civil strife in another Contracting
State, whether or not the government of the latter has been recognized.
a) The contribution, supply or provision of arms and war material;
b) The equipment, training, collection, or transportation of members of a military expedition; or
c) The provision or receipt of money, by any method, intended for the military enterprise.
The present Protocol does not affect obligations previously undertaken by the Contracting States through international agreements.
