wilfully obstructs or is guilty of other misconduct in connection with any medical or other examination which he is required under article 16 to undergo, or with any proceedings under this scheme for the determination of his right to an allowance or to the receipt thereof, he shall forfeit, for such period as the appropriate determining authority shall determine, any allowance which would, apart from this paragraph, be payable.
Nothing in paragraph (1) providing for forfeiture of an allowance for failure to undergo medical examination or other examination or any obstruction or misconduct in connection with such examination shall authorise the disentitlement of the person concerned for a period exceeding 6 weeks on any forfeiture.
