Each amendment that changed this provision, and each that will, oldest first. Each is shown against the wording just before it; where an amendment gives the provision another number, it is followed under the new one. Read it as it stands today
In force today
In an arbitration procedure, an allegation that an arbitral tribunal does not have jurisdiction must be made promptly after the occurrence of the cause for the allegation if the cause has occurred during the course of the arbitration procedure, or, in any other case, an allegation must be made by the time of submission of the first written allegation on the merits (including the time of orally making the first allegation on the merits in oral hearings); provided, however, that this does not apply when the arbitral tribunal finds justifiable grounds for a delay in making an allegation that the arbitral tribunal does not have jurisdiction.
仲裁手続において、仲裁廷が仲裁権限を有しない旨の主張は、その原因となる事由が仲裁手続の進行中に生じた場合にあってはその後速やかに、その他の場合にあっては本案についての最初の主張書面の提出の時（口頭審理において口頭で最初に本案についての主張をする時を含む。）までに、しなければならない。ただし、仲裁権限を有しない旨の主張の遅延について正当な理由があると仲裁廷が認めるときは、この限りでない。
