“14. First, there was a long running and significant issue about the bundles. Following a lengthy CMC the Tribunal gave directions dated8 July 2014 about the preparation of submissions, evidence and hearing bundles. The directions were intended in part to limit excessive and repetitive written submissions and documentations. The purpose is plain. In the words of the overriding objective, a limitation on documentation and written submissions enables the Tribunal “to deal with the case in ways which are proportionate to the importance of the case, the complexity of the issues and the anticipated costs and resources of the parties and of the Tribunal.”
