Taiwan prosecutors drop charges in submarine recordings case

Taipei prosecutors have dismissed charges against several figures, including legislator Hsu Chih-chieh and Belle Island Media chairman Wu Tzu-chia, in a complex legal battle surrounding leaked recordings of discussions about Taiwan's indigenous submarine program. The investigation, which examined accusations of corruption and obstruction related to the "Hai Kun" submarine project, concluded that the audio files were not tampered with and that the released content pertained to public defense matters.

The dispute ignited around the time of the "Hai Kun" submarine's unveiling in September 2023. Former Navy advisor Kuo Hsi accused legislator Ma Wen-chun of leaking submarine data to foreign entities. In response, Ma, Hsu, and Wu released recordings of Kuo and a Korean consultant, alleging illicit activities in the submarine procurement process. This led to a cascade of accusations, including claims of defamation and false reporting.

An investigation into the audio recordings, which were reportedly made by a witness who translated for a Korean firm, found no signs of editing, synthesis, or manipulation. Professional voice and digital analysis supported the authenticity of the speakers, identified as Kuo and others. The recordings, circulating on military websites and media for years prior, were deemed not to have been fabricated by Wu, Zhang, and Hsu.

Prosecutors determined that Wu, Zhang, and Hsu had a basis for their accusations, presenting evidence to the authorities for investigation rather than knowingly making false claims. The discussions, involving submarine models, sonar, engines, and government procurement, were considered significant public interest topics related to national defense autonomy. Consequently, the charges against them were dropped. Similar dismissals were issued for other related cases, including one that had passed the statute of limitations.
