Article 3. Neither the Tribunal, its members nor their alternates can be challenged by the prosecution, or by the Defendants or their Counsel. Each Signatory may replace its member of the Tribunal or his alternate for reasons of health or for other good reasons, except that no replacement may take place during a Trial, other than by an alternate.
Article 4.
(a)
The presence of all four members of the Tribunal or the alternate for any absent member shall be necessary to constitute the quorum.
(b)
The members of the Tribunal shall, before any trial begins, agree among themselves upon the selection from their number of a President, and the President shall hold office during that trial, or as may otherwise be agreed by a vote of not less than three members. The principle of rotation of presidency for successive trials is agreed. If, however, a session of the Tribunal takes place on the territory of one of the four Signatories, the representative of that Signatory on the Tribunal shall preside.
(c)
Save as aforesaid the Tribunal shall take decisions by a majority vote and in case the votes are evenly divided, the vote of the President shall be decisive: provided always that convictions and sentences shall only be imposed by affirmative votes of at least three members of the Tribunal.
Article 5. In case of need and depending on the number of the matters to be tried, other Tribunals may be set up; and the establishment, functions, and procedure of each Tribunal shall be identical, and shall be governed by this Charter.
