(1) The author may require information from the person obliged to pay remuneration pursuant to section 54 or section 54b as to the nature and quantity of appliances and storage mediums sold or otherwise put into circulation within the territory to which this Act applies. The trader’s obligation to provide information also extends to naming sources of supply; it also subsists in the case of section 54b (3) no. 1. Section 26 (7) applies accordingly.
(2) The author may require such information from the operator of an appliance in an institution within the meaning of section 54c (1) as is necessary to assess the amount of the remuneration.
(3) Where the person obliged to pay remuneration does not meet this obligation, or only does so incompletely or otherwise incorrectly, twice the rate of remuneration may be demanded.
