It has been said that there can be no submission unless it deals with some existing dispute between the parties.1 This, however, has been denied and it has been said that a submission may exist, although it does not relate to matters in dispute, but to matters which may be in dispute but for such agreement of submission.2 To a large extent this is, as has been said hereafter,3 merely a question of names. The parties may undoubtedly agree in advance for determining the existence of specific facts,4 and whether such agreement is to be called a submission or not depends upon whether such a method of settling future difficulties is to be regarded as arbitration or not.
