Thailand’s National Legislative Assembly voted  unanimously on December 15 to pass an amendment to the 2007 Computer Crime Act. The new law, which will take effect after 180 days, has been criticized  by several human rights groups for containing provisions that threaten to further undermine freedom of expression in Thailand.
The law was approved by a parliament whose members were appointed by the military, which took power in a coup in 2014. The junta said amending the law is necessary to combat  cybercrimes but critics fear it is really intended to suppress dissent.
An online petition against the legislation led by the Thai Netizen Network has gathered  over 370,000 signatures. The petition cited some of the provisions  in the law which could be used by authorities to intimidate the media and even ordinary Internet users.
For example, section 14 criminalizes the sending of “false computer data” or Internet content that damages “the maintenance of national security, public security, national economic security or public infrastructure serving public interest or cause panic in the public.”
The Bangkok Post newspaper is suspicious  about this provision:
There is no clear definition of what acts may be construed as being in breach of this section. Will criticizing the government's megaprojects qualify as damage to national security or public infrastructure? How about opinions about the state of the country's economy?

Meanwhile, section 15 could lead to self-censorship on the part of local Internet Service Providers because it penalizes all parties that “cooperate [in spreading] false computer data”. This section also allows officials to obtain Internet traffic data from ISPs without court approval. This could also lead to more costs that will negatively affect  both business and consumers.
Section 16 criminalizes the possession of information that the court has ordered to be destroyed. This could hamper  the work of researchers and journalists. Some are worried that the computer cache or Internet browsing history of ordinary netizens can be retrieved by authorities to monitor if they are storing banned content.
Section 18 allows authorities to access encrypted data. It is not clear how this would be carried out in practice.
Section 20 empowers a committee appointed by the government to monitor and even order the removal of dangerous Internet content. The Bangkok Post is referring to this provision when it published an editorial criticizing the amended law:
The draft amendment's most serious shortcoming is in its giving too much power for state authorities to make their own judgement whether certain actions may be deemed in violation of the law.
Even though the law is not yet in effect, authorities are already aggressively blocking ‘harmful’ Internet content, especially those deemed to be disrespectful to the monarchy. Thailand implements a strict lese majeste (anti-royal insult) law which some activists believe is being abused by the junta to harass and detain its critics. According to the government, it shut down  1,370 websites in October for violating the lese majeste law. This is massive compared to the 1,237 websites shut down by the government in the past five years.

Prime Minister Prayuth Chan-ocha defended  the law by insisting that it will not violate civil liberties. Some businesses also welcomed  the passage of the law which they believe will protect intellectual property rights and spur  the development of the digital economy.
But protests were also organized  a few days after the law was approved by the parliament. The online activist group Citizens Against Single Gateway claimed that it hacked  several government websites.

Thai Netizen Network acknowledged the sentiment of Anonymous but it also urged the group to consider the protection of data by ordinary Internet users:
Thx for support, #Anonymous . U made ur point. Further hack may harm Thai citizens more than Junta. Pls u consider avoid citizen data? Thx :)

Several international groups such as the United Nations Human Rights Office  in Asia and the Committee to Protect Journalists  also issued statements expressing concern about the passage of the law.
