Looks like your committee has a problem.
As I understand, your application to Fair Trading named the committee as respondent. So they have to deal with the mediation even if there is no strata manager.
However the legal system is not that unfair. The committee could ask for a time extension because there is no strata manager. FT could then assess the urgency of your application and what disadvantage the committee would suffer prior to making a decision about an extension.
Youll have to bide your time.
