In a decision of April 20, 2012 the District Court Hamburg concluded that the video platform YouTube is only liable for copyright infringements committed by its users if certain control obligations have been violated. If YouTube has been informed about a copyright infringement an immediate reaction, namely blocking the video in question is required. The further control obligations of YouTube have to be determined on the basis of a balance of interests whereby the activity of YouTube which is, in principle, allowed shall not be hampered in an unreasonable manner. The decision is not jet final.
