Bangkok: The National Anti-Corruption Commission (NACC) has ruled that Supa will not appeal the Shinawatra share tax case, a decision made during her tenure as Deputy Permanent Secretary of the Ministry of Finance, which resulted in a 17 billion baht loss to the state.

According to Thai News Agency, the NACC's meeting on April 28 concluded with a narrow 4 to 3 vote, determining that Ms. Supa Piyachitti, a former NACC commissioner, was guilty of malfeasance or dereliction of duty. This decision comes from her inaction regarding the appeal of the Central Tax Court's ruling on Shin Corp shares taxes during her service as Deputy Permanent Secretary of Finance. The Supreme Court's Criminal Division for Holders of Political Positions has ruled that her failure to act to protect the state's interests led to significant financial damage.

The Ministry of Finance and Revenue Department officials involved in the case were expected to challenge the Central Tax Court's judgment, but their inaction resulted in a loss of tax revenue and damaged the civil service systems of both departments. The lack of an appeal means the case is now closed, and the taxes in question can no longer be collected. The NACC plans to forward the case file to the public prosecutor for further legal proceedings.
