The Criminal Code 2015 (Penal Code 2015) is amended and supplemented by Law no. 12/2017/QH14 and takes effect from January 1, 2018, according to Resolution No. 41/2017/QH14.
The Vietnamese version is a unified document. However the English translation doesn't heave a unified document yet, so readers need to read both the Criminal Code 2015 and the amendments and supplements in Law no. 12/2017/QH14.
