"(1) If, on an application made by the Attorney General or the Lord Advocate under this section, the Appeal Tribunal is satisfied that a person has habitually and persistently and without any reasonable ground- (a) instituted vexatious proceedings, whether in an employment tribunal or before the Appeal Tribunal, and whether against the same person or against different persons, or (b) made vexatious applications in any proceedings, whether in an employment tribunal or before the Appeal Tribunal, the Appeal Tribunal may, after hearing the person or giving him an opportunity of being heard, make a restriction of proceedings order."
"(2) A "restriction of proceedings order" is an order that- (a) no proceedings shall without the leave of the Appeal Tribunal be instituted in any employment tribunal or before the Appeal Tribunal by the person against whom the order is made, (b) any proceedings by him in any employment tribunal or before the Appeal Tribunal before the making of the order shall not be continued by him without the leave of the Appeal Tribunal, and (c) no application (other than one for leave under this section) is to be made by him in any proceedings in any employment tribunal or before the Appeal Tribunal without the leave of the Appeal Tribunal."
"(3) A restriction of proceedings order may provide that it is to cease to have effect at the end of a specified period, but otherwise it remains in force indefinitely."
"(4) Leave for the institution or continuance of, or for the making of an application in, any proceedings in an employment tribunal or before the Appeal Tribunal by a person who is the subject of a restriction proceedings order shall not be given unless the Appeal Tribunal is satisfied- (a) that the proceedings or application are not an abuse of the process of the tribunal in question, and (b) that there are reasonable grounds for the proceedings or application."
"(5) A copy of a restriction of proceedings order shall be published in the London Gazette and the Edinburgh Gazette."
"(4) If upon a pre-hearing review the tribunal considers that the contentions put forward by any party in relation to a matter required to be determined by a tribunal have no reasonable prospect of success, the tribunal may make an order against that party requiring the party to pay a deposit of an amount not exceeding£150 as a condition of being permitted to continue to take part in the proceedings relating to that matter."
"No order shall be made under this rule unless the tribunal has taken reasonable steps to ascertain the ability of the party against whom it is proposed to make the order to comply with such an order, and has taken account of any information so ascertained in determining the amount of the deposit."
"The fifth and last issue of law arose out of Mr Jones' wish to challenge the conclusion of various judges in the underlying proceedings that his conduct in those particular proceedings had been vexatious or had involved an abuse of the process of the court. We ruled that he was not free to do so. If any such conclusion was, or was thought by Mr Jones to be, erroneous, the remedy was to appeal in those proceedings … But if that was not done, the decision must stand and is capable of forming the basis for the court being satisfied upon an application under section 42 that Mr Jones had habitually and persistently and without any reasonable ground acted in the manner referred to in subsection 1( a ) or ( b )."
