Section 360.21 - Time of filing(a)General. During January and February of each year, every interested copyright party claiming to be entitled to DART royalty payments made for quarterly periods ending during the previous calendar year must file a claim with the Copyright Royalty Board. Claimants may file claims jointly or as a single claim.(b)Consequences of an untimely filing. No royalty payments for the previous calendar year will be distributed to any interested copyright party who has not filed a claim to those royalty payments during January or February of the following calendar year.(c)Authorization. Any organization or association acting as a common agent for collection and distribution of DART royalty fees must obtain from its members or affiliates separate, specific, and written authorization, signed by members, affiliates, or their representatives, apart from their standard affiliation agreements, for purposes of royalties claim filing and fee distribution relating to the DART Musical Works Fund or Sound Recordings Fund. The written authorization, however, will not be required for claimants to the Musical Works Fund when either:(1) The agreement between the organization or association and its members or affiliates specifically authorizes the entity to represent its members or affiliates as a common agent before the Copyright Royalty Board in royalty claims filing and fee distribution proceedings; or(2) The agreement between the organization or association and its members or affiliates, as specified in a court order issued by a court with authority to interpret the terms of the contract, authorizes the entity to represent its members or affiliates as a common agent before the Copyright Royalty Board in royalty claims filing and fee distribution proceedings.
