[Sanctions]
Should any member of the League resort to war in disregard of its
covenants under Articles Twelve, Thirteen or Fifteen, it shall ipso
facto be deemed to have committed an act of war against all other
members of the League, which hereby undertake immediately to subject it
to the severance of all trade or financial relations, the prohibition
of all intercourse between their nations and the nationals of the
covenant-breaking state and the prevention of all financial,
commercial, or personal intercourse between the nationals of the
covenant-breaking state and the nationals of any other state, whether a
member of the League or not.
It shall be the duty of the Council in such case to recommend to the
several governments concerned what effective military or naval forces
the members of the League shall severally contribute to the armaments
of forces to be used to protect the covenants of the League.
The members of the League agree, further, that they will mutually
support one another in the financial and economic measures which are
taken under this Article, in order to minimize the loss and
inconvenience resulting from the above measures, and that they will
mutually support one another in resisting any special measures aimed at
one of their number by the covenant-breaking state, and that they will
take the necessary steps to afford passage through their territory to
the forces of any of the members of the League which are cooperating to
protect the covenants of the League.
Any member of the League which has violated any covenant of the League
may be declared to be no longer a member of the League by a vote of the
Council concurred in by the representatives of all the other members of
the League represented thereon.
