Are you serious? You seem to be but its bizarre to me that it is not obvious to you that a public official cannot act in this way.
First off, it's slander not least because if wasn't accurate information (Wang was cleared this summer). So no matter what you seem to think, Ma has acted illegally.
What you also fail to grasp is that Wang is not just a personal rival to Ma but the legal and functioning speaker of the legislative. In this capacity he is a representative of the ROC and personal rivalry cannot play any roll in whether he gets to remain in office and perform his duties. It doesn't matter that Ma hates his guts: if Wang sees a piece of law passed then Ma has to sign it. If he didn't because he hates Wang he would clearly be acting unconstitutionally.
However, Ma did take his personal hatred of Wang into the public sphere by trying to destroy him with the illegal evidence. Which of course was not even evidence as Wang was cleared this summer of influence peddling. Taking a private hatred into the public sphere to influence the direction of your country is a gross violation of office. How can you not get that this ethical violation must also be illegal in any functioning democracy?
Do you really think president Obama could use the Justice Department to investigate a sitting senator and then use information he obtained (legally or not) to try and have that person lose his seat? It is one thing to sling dirt at a rival in an election. It is another to abuse your position to try to force another person out of legal office.
Again, how is this not illegal in a democracy and how can you possibly defend this? Ma abused his position.
No. Are you insane to think a president is allowed to unseat someone simply because he doesn't like him?
The president has no right to go after another politician.
Certainly an abuse of office and so certainly illegal.
You mean dictator who is above the rule of law. Ma took his personal hatred and used the power of his office to enact revenge. And you think that is okay?
