Internet Freedoms in Thailand reviews and analyses legislation that impacts internet freedoms in Thailand. These include provisions in the Constitution, Penal Code, the Computer Crime Act, the Cybersecurity Act, and the Emergency Decree. As this report shows, many provisions under these laws contain vague language enabling wide interpretation, impose harsh punishment, and give far-reaching power to the authorities. Today, internet freedoms in Thailand remain under threat, a product of continuous restrictions accelerated since the 2014 coup. These laws are used to justify removing or blocking content criticising the monarchy and establishment, prosecuting internet users, and harassing activists, individuals, journalists, and human rights defenders. This has led some sectors of Thai society to practise self-censorship, while others choose to defy the regime. Recommendations on upholding internet freedom in Thailand provided in this report include: to amend or repeal provisions containing vague language and imposing harsh penalties; decriminalise defamation and place it within the civil code; and limit the application of the Emergency Decree strictly as necessary.
