Although the under the Thai Criminal Code, euthanasia might be deemed unlawful, however under the Civil Code it is not necessarily so:
“When euthanasia, whether active or passive, is performed without the patient’s consent, the doctor will be charged with a tort, and is required to pay the reparation. In case where euthanasia is accomplished with the patient’s own consent, the principle volunti non fit injuria is applied as a general principle of law even though the very same act would be criminally condemned,” (Santivasa, N.D.)[3].
