Where any question is to be decided by the Secretary of State under this Act or under any rule, regulation or order made thereunder, then, if in the opinion of the Secretary of State the medical examination of any pupil would assist the determination of the question, the Secretary of State may by notice in writing served on the parent of that pupil, if the pupil is enrolled at a school, or on the pupil himself if he is enrolled at a junior college or other educational establishment, require the parent to submit him, or require the pupil to submit himself, as the case may be, for such examination; and if any person on whom such a notice is served fails without reasonable excuse to comply with the requirements thereof, he shall be liable on summary conviction to a fine not exceeding £10.
