Is the private-copy levy system of Austrian copyright law compatible with the EC’s InfoSoc Directive 2001/29 when national law: (a) puts the levy on all blank recording-media irrespective of whether the media are marketed to intermediaries, to natural or legal persons and for use other than for private purposes; (b) offers refunds in some circumstances but not others; and (c), only pays authors half of the net ‘fair compensation’ monies collected and gives away the other half to Austrian cultural organisations?
