"Thank you for your email. … The deadlines I referred to are set out in your letter accompanying the decision notice. In this case there is a deadline of 1 month from the date of the decision to request a set aside. One of the grounds for set aside can be that a document that was in front of the Tribunal was not in front of the Commissioner. I have no way of knowing that all the documents in front of the Tribunal were placed before the Commissioner without seeing the file."
