A written decision by the majority of the Chamber, in either a Regional Court, or the International Court, shall be published in an official reporter. Dissenting opinions shall also be published, and each judge may write separately or join in an opinion by a group.
Judges, like other humans, will not agree. It may be that over time the minority view becomes the majority view. Concurrences and dissents are treated with respect and are included with majority opinions in official reporters.
