Swedish prosecutors filed charges on 31 January 2008 against Fredrik Neij, Gottfrid Svartholm, and Peter Sunde, who ran the site; and Carl Lundström, a Swedish businessman who through his businesses sold services to the site. The prosecutor claimed the four worked together to administer, host, and develop the site and thereby facilitated other people's breach of copyright law.

Swedish law has only gotten more strict since 2008 with regard to copyright.
