9. A person shall be disqualified from receiving a severe disablement allowance for such period not exceeding 6 weeks as may be determined in accordance with sections 97 to 104 of the Act if—
(a)he has become incapable of work through his own misconduct, except that this disqualification shall not apply where the incapacity is due to venereal disease; or
(b)he fails without good cause to comply with a notice in writing given by or on behalf of the Secretary of State requiring him to attend for and to submit himself to medical or other examination on a date not earlier than the third day after the day on which the notice was sent and at a time and place specified in that notice; or
(c)he fails without good cause to attend for, or submit himself to, medical or other treatment; so however that this disqualification shall not apply to any failure to attend for or to submit to vaccination or inoculation of any kind or to a surgical operation, unless the failure is a failure to attend for or to submit to a surgical operation of a minor character, and is unreasonable; or
(d)he fails without good cause to observe any of the following rules of behaviour, namely:—
(i)to refrain from behaviour calculated to retard his recovery, and to answer any reasonable enquiries (not being enquiries relating to medical examination, treatment or advice) by the Secretary of State or his officers directed to ascertaining whether he is doing so;
(ii)not to be absent from his place of residence without leaving word where he may be found;
(iii)to do not work for which remuneration is, or would ordinarily be, payable unless it is—
(aa) work which is undertaken under medical supervision as part of his treatment while he is a patient in or of a hospital or similar institution, or
(bb) work which is not so undertaken and which he has good cause for doing,
and from which, in the case of work of either description, his earnings, if any, are ordinarily not more than £23.50 a week.
