On August 23, 2017 Mr. Mioduszewski delivered a lecture for ELSA Łódź during the “IInd Film Law School”. The subject of the lecture were so-called “additional royalties” for co-authors and artistic performers of the audiovisual works (Article 70 section 2(1) and 3 of the Copyright Act), an interesting institution of the Polish copyright law which is the source of numerous legal and economic controversies. The issue was presented on the background of the example of the first Polish court claim for “additional royalties” for actors of a docu-crime TV series, still pending before courts.
