The Clearing Body for Copyright on the Internet (CUII) is an independent body in Germany. It was founded by German internet access providers and copyright holders to objectively examine whether the blocking of access to a given structurally copyright-infringing website in Germany is lawful. When copyright holders submit an application, a review board examines whether the relevant requirements are met. If they are, the review board then recommends a DNS-block of the structurally copyright-infringing website in question.
Every recommendation of the review committee must be unanimous and only apply to clear cases of copyright infringement. The recommendation is then forwarded to the German Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railways (Bundesnetzagentur - BNetzA). If the examination by the BNetzA does not reveal any concerns about the DNS-block according to the provisions of the EU Net Neutrality Regulation (Regulation (EU) 2015/2120), the CUII then informs the internet access providers and the applicants accordingly.
In such cases, the internet access providers participating in the CUII then block the corresponding domains of the structurally copyright-infringing website in Germany.
