17.—(1) Where a party pays a fee at a time when that party would have been entitled to a remission if they had provided the documentary evidence required by paragraph 14, the fee, or the amount by which the fee would have been remitted as the case may be, must be refunded if documentary evidence relating to the time when the fee became payable is provided at a later date.
(2) Where a fee has been paid at a time when the Chief Executive of the Supreme Court, if all the circumstances had been known, would have remitted the fee under paragraph 15, the fee or the amount by which the fee would have been remitted, as the case may be, must be refunded to the party.
(3) No refund may be made under this paragraph unless the party who paid the fee applies within 3 months of the date on which the fee was paid.
(4) The Chief Executive of the Supreme Court may extend the period of 3 months mentioned in sub-paragraph (3) if the Chief Executive of the Supreme Court considers that there is a good reason for a refund being made after the end of the period of 3 months.
