51. The Commission shall retain all the information concerning a registered person for a period of five years from the date on which the Commission declares the person’s total disqualification. The same applies, from the same time, in the case of a person who is not registered but who is declared totally disqualified, from the date of the Commission’s refusal in the case of a person who is not registered as a result of a refusal by the Commission, or from the date on which the payment referred to in section 13 became payable in the case of a registered person who ceased to be registered as a result of failure to maintain the person’s rights as an owner or operator.
