Class Action Lawsuits and Proceedings in Thailand

Thailand - On 8th April 2015 there was an amendment of the Civil Procedure Code - B.E. 2558 (2015) was promulgated into the Royal Thai Government Gazette. This amendment to the Civil Procedure Code introduced class action proceedings, into the Thai legal system.

Originating from Anglo-Saxon law the class action lawsuit involves several injured parties who do not all have to start their own legal actions in order to receive a court reward out of the class action case. Therefore, the class action lawsuit can provide efficiency and facilitate justice in certain cases with a large number of parties. It can bring justice for injured persons who would otherwise not seek compensation. Even small claims of numerous people can add up to a considerable or even huge value of the aggregated claims. The typical model case would be a consumer protection case with many injured individuals against the responsible corporation. In theory class actions strengthen the procedural rights of less privileged social groups. Can the practice of class action in Thailand keep this promise? We will monitor class action cases.

The initial concept of draft law on Class Action Act was mainly adopted from the United States Federal Rules of Civil Procedure. It might be worth to carefully study the application of the US class action law in Thailand as class actions until now foreign to the Thai legal system are well-established in the United States. This even more as the new Thai class action is surprisingly vague regarding central issues, e.g. regarding the group of people who shall be bound and entitled by the class action called “class members” under the new law (the new law contains a provision for the opting-out of class members, but is not clear as to whether a person will be a class member eo ipso by fulfilling the statutory requirements or whether a constitutional act is required).

On the other hand the new class action amendment contains provisions for the procedure during and in preparation of court hearings, e.g. regarding evidence owned by the counterparty, the testimony and questioning of parties, matters in dispute etc. which in such detail are not even regulated in the Thai Civil Procedure Code for all other types of procedures which involve no class action.

There are limitations as to what extent US interpretations and precedents can be used to interpret the new Thai class action law, as the common law system of the US is based on different principles and a different legal culture than the Thai system which follows the continental-European civil law.

The introduction of the class action into the Thai Civil Procedure Code amounts to an exception to the fundamental principle that the right to sue lies only with the party who is affected in their own rights. This principle which is comparable to the Anglo-Saxon “locus standi” governs the Thai civil procedure as prescribed in Section 55 of the Thai Civil Procedure Code: only the persons whose rights are involved is entitled to submit a lawsuit to a civil court. By contrast, under the new class action law a plaintiff and the plaintiff’s attorney will have an extraordinary leading role and submit a lawsuit for all “class members” who will be bound by the decisions of the court in the class action case. This also means that the class members will automatically forfeit their rights to bring a new lawsuit as Section 144 of the Civil Procedure Code prescribes that an adjudicated case may generally not be tried again. If a person regarded as a class member wishes to avoid being bound by the class action proceeding, they would need to formally opt-out.

The class action lawsuits which may be filed must involve wrongful acts or breach of contracts or other forms of losses arising from specific laws; environment law, consumer protection law, security and exchange law, competition law and labor law as well.

The plaintiff of class members can file a lawsuit together with a request to commence a class action to the Court. Thereafter, the Judge will consider and send the copy of those to the defendant. If the request is approved, the Judge will send the notice to class members and publish on the well-known newspaper 3 days continually so in case any member would exclude from this class (opt-out), shall send a correspondence to the Court within the prescribed period. The notice shall include the important information i.e. the rights of the class member, binding of final judgment, detail of Court and case.

2. Grant full repayment

3. Grant partial repayment
