Offences relating to illegal activities with the use of computers are known as cyber crimes and the Thai government has realised the need to have a clear legal mechanism to cope with such offences. Thus, the "Computer-Related Offences Commission Act B.E. 2550" (the "Act"), has been enacted and became effective on 18 July 2007.

The Act was published in the Royal Gazette on 18 June 2007 and became effective the same day. The Act consists of 2 chapters being Computer-Related Offences and the Competent Officials.

The first chapter, Computer-Related Offences, prescribes the acts that are considered computer crimes such as:

1.2 contains false information in a manner that is likely to cause damage to the country's security or to cause a public panic;

1.3  contains information which is related to offences on the country's security or to do with terrorism.

1.4  contains obscene information, which is publicly accessible.

Any person, who is aware of the information as mentioned above, and disseminates or forwards such information, is also liable. 
In addition, service providers who intentionally associate or allow for the above-mentioned offences to be committed via their networks are also subject to penalties.

2.  Providing access to publicly accessible computer systems that contain pictures of other persons, which have been recreated or modified and that are likely to cause such persons to be defamed, insulted or embarrassed.

The second chapter of the Act prescribes details of the authorities and the functions of the Competent Officials who shall act under the law.

If there is reasonable cause to believe that there is an offence committed under this Act, then a competent official shall have the authority to:

4.1  issue an inquiry letter to any person related to the offences under the Act or summon them to give statements, submit written explanations or any other documents, data or evidence deemed necessary;
