69.—(1) Where the Secretary of State is satisfied that a person who has sustained a qualifying injury should in his own interests receive medical, surgical or rehabilitative treatment for that injury, and that person refuses or neglects to receive the treatment, the Secretary of State may, if he considers that such refusal or neglect is unreasonable, withhold or cancel any award of a pension in respect of that injury which may be or has been made or may reduce the amount of any such pension.
(2) For the purpose of this Article any misconduct on the part of a person which, in the opinion of the Secretary of State, renders it necessary for any treatment that he is receiving to be discontinued may be treated as a refusal of the person to receive the treatment.
