Only one prosecution witness remains to be examined in the immigration law case of Australian economist Sean Turnell, according to a source close to the court.

After examining all the witnesses, the charges must be filed. The court will then decide whether to accept the charges.

If the charges are accepted the case will continue and the accused will have to submit a list of witnesses.

Turnell, an Australian economist and former economic advisor to the Aung San Suu Kyi government is currently facing two charges, the alleged breaking of the Immigration Law and a charge under Section 3 (1) (c) of the Official Secrets Act.

He was charged with Section 3 (1) (c) of the Official Secrets Act along with State Counselor Aung San Suu Kyi, former Union Minister for Finance and Industry, Soe Win, former Deputy Minister Set Aung and former Union Minister Kyaw Win.

These cases are being heard in Naypyidaw every Thursday. But the last hearing was postponed, because former Minister Soe Win's lawyer was not allowed to enter Naypyidaw because he had a high fever.

Turnell was arrested in Yangon five days after Myanmar's military overthrew the elected government just over 12 months ago. The charge under Myanmar's Official Secrets Act carries a maximum penalty of 14 years in prison if found guilty.

The Australian government has called on the Myanmar regime to release Turnell.
