Appeals: Decision

The Appeals Resolution Officer will review the information in the claim file and any additional information you submit on the Appeal Readiness form or the Respondent form to make their decision. If there is an oral hearing, the Appeals Resolution Officer will also consider the testimony and arguments made during the hearing.

Clarifying an appeal decision

If a party to the appeal receives a decision and finds it to be unclear, incomplete or to have an obvious error (e.g., a typographical error that does not impact the decision) you can write to the Appeals Resolution Officer directly and ask them to provide you with a clarification.

An Appeals Resolution Officer can issue an addendum to clarify their decision, correct a date, or complete an incomplete decision.

Requesting a clarification is not the same as formally disagreeing with a decision.
