A/HRC/17/27 1. Arbitrary blocking or filtering of content on the Internet 70. The Special Rapporteur is deeply concerned by increasingly sophisticated blocking or filtering mechanisms used by States for censorship. The lack of transparency surrounding these measures also makes it difficult to ascertain whether blocking or filtering is really necessary for the purported aims put forward by States. As such, the Special Rapporteur calls upon States that currently block websites to provide lists of blocked websites and full details regarding the necessity and justification for blocking each individual website. An explanation should also be provided on the affected websites as to why they have been blocked. Any determination on what content should be blocked must be undertaken by a competent judicial authority or a body which is independent of any political, commercial, or other unwarranted influences. 71. With regard to child pornography, the Special Rapporteur notes that it is one clear exception where blocking measures are justified, provided that the national law is sufficiently precise and there are sufficient safeguards against abuse or misuse to prevent any “mission creep”, including oversight and review by an independent and impartial tribunal or regulatory body. However, the Special Rapporteur calls upon States to focus their efforts on prosecuting those responsible for the production and dissemination of child pornography, rather than on blocking measures alone. 2. Criminalization of legitimate expression 72. The Special Rapporteur remains concerned that legitimate online expression is being criminalized in contravention of States’ international human rights obligations, whether it is through the application of existing criminal laws to online expression, or through the creation of new laws specifically designed to criminalize expression on the Internet. Such laws are often justified as being necessary to protect individuals’ reputation, national security or to counter terrorism. However, in practice, they are frequently used to censor content that the Government and other powerful entities do not like or agree with. 73. The Special Rapporteur reiterates the call to all States to decriminalize defamation. Additionally, he underscores that protection of national security or countering terrorism cannot be used to justify restricting the right to expression unless it can be demonstrated that: (a) the expression is intended to incite imminent violence; (b) it is likely to incite such violence; and (c) there is a direct and immediate connection between the expression and the likelihood or occurrence of such violence. 3. Imposition of intermediary liability 74. Intermediaries play a fundamental role in enabling Internet users to enjoy their right to freedom of expression and access to information. Given their unprecedented influence over how and what is circulated on the Internet, States have increasingly sought to exert control over them and to hold them legally liable for failing to prevent access to content deemed to be illegal. 75. The Special Rapporteur emphasizes that censorship measures should never be delegated to private entities, and that intermediaries should not be held liable for refusing to take action that infringes individuals’ human rights. Any requests submitted to intermediaries to prevent access to certain content, or to disclose private information for strictly limited purposes such as administration of criminal justice, should be done through an order issued by a court or a competent body which is independent of any political, commercial or other unwarranted influences. 20
