(1) The author may revoke a right of use vis-à-vis the rightholder if the work no longer reflects the author’s conviction and the author can therefore no longer be expected to agree to the exploitation of the work. The author’s successor in title (section 30) may exercise the right of revocation only if he or she can prove that the author would have been entitled to exercise this right prior to his or her death and was prevented from exercising the right or provided for its exercise by testamentary disposition.
(2) The right of revocation may not be waived in advance. Its exercise may not be precluded.
(3) The author must adequately compensate the holder of the right of use. The compensation must at least cover the costs which the holder of the right of use incurred until such time as the revocation was declared; however, no account is taken of costs attributable to those uses of the work which have already been made. The revocation does not become effective until the author has reimbursed the costs or provided security therefor. The holder of the right of use is to inform the author of the amount of the costs within three months after the revocation is declared; if the holder of the right of use does not fulfil this obligation, the revocation becomes effective upon the expiry of this period.
(4) If the author wishes to resume exploitation of the work after revocation, he or she is obliged to offer a corresponding right of use to the previous holder of the right of use on reasonable conditions.
(5) The provisions of section 41 (5) and (7) apply accordingly.
