When any dispute is heard in a tenancy court/tribunal, a determination is made by an Adjudicator, Magistrate or Registrar based solely on the objective facts.
Their decision then becomes final. Any avenues to appeal are generally both time-consuming and very costly. Therefore, it is often wise to mediate and discuss the matter before considering legal action. This obviously will vary largely on a case-to-case basis and can come down to something as simple as it being a matter of principle for one of the parties, rather than an exercise of maximising the financial outcome. However, as the saying goes 'A large percentage of something is a lot better than a hundred percent of nothing'.
If a dispute arises and an outcome is achieved prior to a hearing that is very close to acceptable, sometimes it is worth considering taking this and moving on, rather than risk a potentially reduced decision being made.
