Article 26 Preliminary issues
(1)
The Tribunal may order any point which appears to be in issue in a case before it to be determined as a preliminary issue.
(2)
If, in the opinion of the Tribunal, the determination of that point substantially disposes of the whole case, subject to rule 20 the Tribunal may treat the hearing of the preliminary issue as the hearing of the case and may make such order by way of disposing of the case as it thinks fit.
