The Brussels court of appeals recently referred the case of Sabam versus  Scarlet regarding the liability of internet service providers to the  Court of Justice of the European Union for a preliminary ruling. Sabam, a  collecting society, initiated a claim against the internet service  provider Scarlet, to prevent that on Scarlet’s servers illegal music and  video files would be exchanged via a peer-to-peer network. The first  court ruled that Scarlet could be held as an intermediary and had to  take active steps to prevent such unlawful file sharing, but Scarlet  appealed.
 
 The court of appeals now considers that the Belgian Copyright Act,  which states that the national courts may issue an injunction against  intermediaries whose services are used by a third party to infringe a  copyright or related right, must be interpreted in light of the European  directives regarding copyright in the information society, regarding  the enforcement of intellectual property rights and regarding data  protection, as well as in light of the European Convention on the  Protection of Human Rights and Fundamental Freedoms. 
 
 The European Court of Justice will have to decide whether such a  provision of national law may lead to an obligation of an internet  service provider “to introduce, for all its customers, in abstracto and  as a preventive measure, exclusively at the cost of that ISP and for an  unlimited period, a system for filtering all electronic communications,  both incoming and outgoing, passing via its services, in particular  those involving the use of peer-to-peer software, (…) and subsequently  to block the transfer of [unlawful] files.” 
 
 Hopefully, the Court of Justice will strike an equitable balance  between the interests of the holders of intellectual property rights and  those of the service providers who should not have a general burden to  police their own customers.
