According to Article 52 of the Constitution, the president is not, without having been recalled or having been relieved of his duties, liable to criminal prosecution unless he is charged with having committed an act of rebellion or treason.
This article explains presidential immunity, and since that is a privilege that is given in order to protect the office of the president, not the president as an individual, the president does not have the right to relinquish it. As for the right to immunity itself, that is merely a temporary procedural barrier; once the president steps down, any criminal offense that he or she might have committed during the presidency can still be prosecuted.
However, whether the immunity also precludes searches of the president’s office or summoning the president to testify is not clearly stipulated in the article.
This lack of clarity became more controversial when the Supreme Prosecutors’ Office’s anti-corruption team searched the president’s office in connection to investigations into the special allowance fund when former president Chen Shui-bian (陳水扁) was still in office. This forced Chen to file a request for a constitutional interpretation, to which the Council of Grand Justices gave Interpretation No. 627. Pursuant to the intent of this interpretation, although no investigation, prosecution or trial may be commenced against an incumbent president, necessary evidentiary preservation may still be conducted, such as the investigation of a crime scene and inspection of objects.
The problem is that such an investigation could invade the president’s right to maintain secrecy. Hence the Council of Grand Justices explicitly stated that, unless relevant provisions of the Code of Criminal Procedure (刑事訴訟法) are amended to restrict the search and seizure in places where the president carries out his functions and resides, law enforcement agencies should, in order to protect state secrets, call on the president to willingly produce the evidence. If the president refuses to do so, prosecutors can file a motion with the High Court, which can assemble a special tribunal made up of five judges to decide if a search warrant should be issued.
However, not only does the Council of Grand Justices’ explanation conflict with the Code of Criminal Procedure and give the impression that the justices are superior to lawmakers, it also complicates the procedure, erecting more barriers against investigations into any criminal offenses committed by the president.
As such, regarding the case of illegal political donations in which President Ma Ying-jeou (馬英九) might be involved, the Special Investigation Division can, if necessary, file an application for a search warrant with the court in order to search the president’s offices, residence and the Chinese Nationalist Party’s (KMT) offices. It can also summon the president to testify as a witness or a relevant party.
However, the president can still easily reject such searches or summons to testify on the grounds that state secrets are involved. In addition, since the Council of Grand Justices set up such high barriers against issuing a search warrant, the chances that prosecutors will be allowed to search the president’s offices and residence are indeed very slim.
Besides, there is unfortunately also a big question mark as to whether the Special Investigation Division has the wisdom, as well as the courage, to uncover any corruption or criminal offenses committed by the person in power.

As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
An elderly mother and her daughter were found dead in Kaohsiung after having not been seen for several days, discovered only when a foul odor began to spread and drew neighbors’ attention. There have been many similar cases, but it is particularly troubling that some of the victims were excluded from the social welfare safety net because they did not meet eligibility criteria. According to media reports, the middle-aged daughter had sought help from the local borough warden. Although the warden did step in, many services were unavailable without out-of-pocket payments due to issues with eligibility, leaving the warden’s hands
Japanese Prime Minister Sanae Takaichi on Monday announced that she would dissolve parliament on Friday. Although the snap election on Feb. 8 might appear to be a domestic affair, it would have real implications for Taiwan and regional security. Whether the Takaichi-led coalition can advance a stronger security policy lies in not just gaining enough seats in parliament to pass legislation, but also in a public mandate to push forward reforms to upgrade the Japanese military. As one of Taiwan’s closest neighbors, a boost in Japan’s defense capabilities would serve as a strong deterrent to China in acting unilaterally in the
Taiwan last week finally reached a trade agreement with the US, reducing tariffs on Taiwanese goods to 15 percent, without stacking them on existing levies, from the 20 percent rate announced by US President Donald Trump’s administration in August last year. Taiwan also became the first country to secure most-favored-nation treatment for semiconductor and related suppliers under Section 232 of the US Trade Expansion Act. In return, Taiwanese chipmakers, electronics manufacturing service providers and other technology companies would invest US$250 billion in the US, while the government would provide credit guarantees of up to US$250 billion to support Taiwanese firms
