Transnational money laundering is a global issue that requires international solutions. This paper examines the concept of Free Movement of Judgments which should be realized in the legal integration process of the ASEAN in order to overcome the negative impacts of money laundering. This research will analyze the regulation for criminalizing money laundering in the ASEAN and compare it with the criminal cooperation in the European Union. The ASEAN Treaty on Mutual Legal Assistance in Criminal Matters (MLAT 2004) is expected to be an alternative to an extradition treaty. If adopting the Free Movement of Judgements, judicial decisions of an ASEAN member country regarding transnational crimes of money laundering would be recognized and implemented in other member’s jurisdiction reciprocally. This adoption is expected to be an effective solution to overcome impunity in cross-border money laundering actors.
