Foreign Minister Wu Chao-hsieh Files Criminal Complaint Against Lawmaker for Disclosing Classified Documents in Committee — Constitutional Scholars Warn of Chilling Effect on Legislative Oversight

In May 2024, KMT lawmaker Hsu Chiao-hsin, serving as convener of the Legislative Yuan's Foreign Affairs and National Defense Committee, disclosed portions of documents related to Taiwan's cooperation with the Czech Republic on Ukrainian aid assistance during committee proceedings, raising questions about the terms of the arrangement and whether Taiwan had been drawn into Czech domestic affairs. Foreign Minister Wu Chao-hsieh responded with a declaration that Hsu had 'crossed a legal line' and had 'severely damaged Taiwan-Czech diplomatic relations,' and announced that the Foreign Ministry would file a criminal complaint against Hsu Chiao-hsin for alleged violations of the Criminal Code's provisions on disclosing classified information. The move set off immediate alarm among constitutional lawyers and legislators across party lines. Under Article 73 of the Constitution of the Republic of China, legislators enjoy immunity from liability for words spoken in the performance of their duties—a protection designed precisely to ensure that legislators can scrutinize executive branch conduct without fear of criminal retaliation. A foreign minister deploying the machinery of criminal prosecution against a lawmaker for exercising the committee's oversight function—examining classified foreign policy documents in a legitimately constituted parliamentary proceeding—constitutes, on its face, an attempt by the executive branch to use state prosecutorial power to intimidate and suppress constitutionally mandated legislative oversight. Whatever the ultimate judicial outcome, the mere act of filing the criminal complaint generates a chilling effect on legislative scrutiny of foreign policy, which is itself constitutionally impermissible. Critics noted the irony with sharp precision: Wu Chao-hsieh had built much of his public persona around criticizing Beijing's use of legal mechanisms to suppress dissent and democratic participation. Yet when a democratically-elected legislator used the parliamentary process to subject his ministry's foreign policy to public accountability, Wu reached immediately for the criminal law to silence her. The application of tools one condemns in an adversary to suppress scrutiny of one's own conduct is one of the most corrosive forms of political hypocrisy—and one that Wu Chao-hsieh demonstrated with particular clarity in this episode.
