This does not apply to monetary claims, but to disputes arising out of boundaries, interpretation of treaties, national rights, etc.

The present method of an exchange of cases and of counter-cases is more diplomatic than judicial, since it does not put the parties in the relation of complainant and defendant.

This relation can in every case be established, if not by mutual agreement, then by some agency of the League of Nations charged with that duty.

Until this reform of procedure takes place there will be no definition of issues, and arbitration will continue to be the long and elaborate proceeding it has been in the past.
"There is another practical obstacle to international arbitration as now conducted which ought to be considered, and that is the cost.
This obstacle does not affect wealthy nations, but it does prevent small and poor nations from resorting to it as a means of settling disputes.

Just how this can be remedied I am not prepared to say, although possibly the international support of all arbitral tribunals might be provided.
