An adjudicator’s decision can generally be appealed to an RTB Tribunal within 10 working days of the decision being issued. A Tribunal’s determination order can generally be appealed to the High Court within 28 days, but only on a point of law rather than simply because you disagree with the outcome. The High Court process is separate from the RTB’s dispute resolution service, so legal advice may be sensible. Check the RTB’s current guidance and appeal forms carefully, as the relevant deadline and procedure depend on the decision and how it was served.
