“a tribunal or court might sist proceedings against the wish of a party if it considered that a decision in another court would be of material assistance in resolving the issues before the tribunal or court in question and that it was expedient to do so.”
“(3) The Tribunal may strike out the whole or a part of the proceedings if— (a) …; (b) …; or (c) the Tribunal considers there is no reasonable prospect of the appellant’s case, or part of it, succeeding.”
“In our judgment an application to strike out in the FTT under Rule 8(3)(c) should be considered in a similar way to an application underCPR 3.4 in civil proceedings (whilst recognising that there is no equivalent jurisdiction in the First-tier Tribunal Rules to summary judgment under Part 24). The Tribunal must consider whether there is a realistic, as opposed to a fanciful (in the sense of it being entirely without substance) prospect of succeeding on the issue at a full hearing, see Swain v Hillman[2001] 2 All ER 91 and Three Rivers (see above) Lord Hope at [95]. A ‘realistic’ prospect of success is one that carries some degree of conviction and not one that is merely arguable, see ED & F Man Liquid Products v Patel[2003] EWCA Civ 472 The tribunal must avoid conducting a ‘mini-trial’. As Lord Hope observed in Three Rivers , the strike out procedure is to deal with cases that are not fit for a full hearing at all.”
