The court jailed Anat Hayeemasae for 22 years and six months.
Anat was convicted of kidnapping Rohingya people who were forced to live in a border camp under his control until their relatives paid ransoms. Last year, a lower court convicted Anat of trafficking.
The Appeals Court, however, allowed Rohingya victims to become co-plaintiffs in the case against Anat. Initially, victims were not allowed to join as co-plaintiffs because the lower court interpreted human trafficking as a crime against the state. The Appeals Court ruled on the case on October 20.
