ARTICLE IX

In the event of a dispute arising between one of the Contracting Powers
and a Power not a party to this Covenant, the Contracting Power involved
hereby binds itself to endeavour to obtain the submission of the dispute
to judicial decision or to arbitration. If the other Power will not
agree to submit the dispute to judicial decision or to arbitration, the
Contracting Power shall bring the matter to the attention of the Body of
Delegates. The Delegates shall in such a case, in the name of the League
of Nations, invite the Power not a party to this Covenant to become _ad

arbitration, and if that Power consents it is hereby agreed that the
provisions hereinbefore contained and applicable to the submission of
disputes to arbitration or discussion shall be in all respects
applicable to the dispute both in favour of and against such Power as if
it were a party to this Covenant.

In case the Power not a party to this Covenant shall not accept the
invitation of the Delegates to become _ad hoc_ a party, it shall be the
duty of the Executive Council immediately to institute an inquiry into
the circumstances and merits of the dispute involved and to recommend
such joint action by the Contracting Powers as may seem best and most
effectual in the circumstances disclosed.

contrary to such recommendation, the Contracting Powers shall thereupon
cease all commerce and communication with that Power and shall also
unite in blockading and closing the frontiers of that Power to all
commerce or intercourse with any part of the world, employing jointly
any force that may be necessary to accomplish that object. The
Contracting Powers shall also unite in coming to the assistance of the
Contracting Power against which hostile action has been taken, combining
their armed forces in its behalf.

In case of a dispute between states not parties to this Covenant, any
Contracting Power may bring the matter to the attention of the
