(i) an employment tribunal which is accused of bias should attempt to defuse the situation, perhaps by a short adjournment or simply by ignoring the allegation, rather than (to adopt a convenient American term) simply recuse itself;
(ii) an advocate's ostensible or implied authority does not extend (in the absence of ratification) to abusing the judicial process and therefore the party represented can dissociate himself from such conduct;
(iii) "scandalous" in the context of the employment tribunal rules of procedure which give a tibunal power to strike out a claim which is "scandalous, frivolous or vexatious" means the misuse of the privilege of legal process in order to vilify others or the giving of gratuitous insult to the court in the course of such process.
