The most serious case Ah Bian is liable had not yet got any sign of prosecution. That is treason that is death penalty liability. In which he at made application in USA Federal Court to demand Pentagon to exercise Occupational Power & Sovereignty on Taiwan, that he claimed that his role as Taiwanese President was a capacity of Proxy Ruler (aka puppet governance) for Washington which is supposed to be in control of Taiwan after WW2 that Japan had surrendered to USA and handed Taiwan over to USA. As an ex-president to make such an assertion on compromised sovereignty of state is 100% treason, no escape. Yet the heat on this is too high that Ma Ying Jiu is unable to handle and had obviously put case on hold. Charging Ah Bian with a death liable charge will upset KMT Ma's vote. That is why Democracy is a very fragile vulnerable and weak system of Pussy. It is unable to put serious thing into right places at all, and any attempt to handle anything as strongly as necessary will break yourself as president / ruling party. Charging ex-president for money laundering about as hard as it can go, no further than that.
