“(1) When an application is filed in accordance with section 86, the chief executive may refer it to a Tenancy Mediator unless, in terms of any regulations made under this Act or of any directions given by the Principal Tenancy Adjudicator, the application is of a class that is to be referred directly to the Tribunal, in which case the chief executive must refer the application to the Registrar.
“(2) Despite subsection (1), if either party informs the chief executive that that party refuses to have the matter considered by a Tenancy Mediator, the chief executive must refer the application to the Registrar.”
