You can ask a dispute resolution officer to correct a mistake in the decision within 15 days of receiving it. For example, if you won at dispute resolution but there is no mention of getting your $50 filing fee back, it may be a mistake. You can also ask for reasons for the decision, if they are missing or not clear. You must fill out a form from the Residential Tenancy Branch called [http://www.rto.gov.bc.ca/documents/RTB-6.pdf Request for Correction] or [http://www.rto.gov.bc.ca/documents/RTB-638.pdf Request for Clarification].
