or states not members of the League shall be
invited to accept the obligations of membership in the League for the
purposes of such dispute, upon such conditions as the Council may deem
just. If such invitation is accepted, the provisions of Articles Twelve
to Sixteen inclusive shall be applied with such modifications as may be
deemed necessary by the Council.

Upon such invitation being given, the Council shall immediately
institute an inquiry into the circumstances of the dispute and
recommend such action as may seem best and most effectual in the
circumstances.

If a state so invited shall refuse to accept the obligations of
membership in the League for the purposes of such dispute, and shall
resort to war against a member of the League, the provisions of Article
Sixteen shall be applicable as against the state taking such action.

If both parties to the dispute, when so invited, refuse to accept the
obligations of membership in the League for the purposes of such
dispute, the Council may take such measures and make such
recommendations as will prevent hostilities and will result in the
settlement of the dispute.
