Three Legislative Yuan budget evaluations log 23 drone-caused airport closures in Taiwan between FY2019 and August 2023, and every row's response column repeats one sentence: on notification, go to the scene with the Aviation Police and investigate. Article 99-13(6) of the Civil Aviation Act gives an airport the verb 'enforce against', not 'stop or remove' — yet the FY2024 report says every airport has already procured handheld jammers.
Paragraphs 3 and 4 of Article 99-13 of the Civil Aviation Act say 'government agencies, schools or legal persons', but paragraph 7's proviso — the only sentence letting a site operator 'take appropriate measures to stop or remove' a drone — says only 'government agencies', and Taipower, CPC and the fabs are legal persons. Their remaining path is to have a municipality announce a restricted zone and 'enforce against' violators, which drops the penalty from an NT$300,000 minimum to an NT$300,000 maximum, while importing a jammer requires 'critical infrastructure provider' status that you learn you hold by receiving a letter.
Eight municipal police departments now run drone units, and the authority to fly is clear — Article 99-16(2) of the Civil Aviation Act exempts agencies performing statutory duties. But that is a flight-safety exemption: a Taipei City legal opinion says it 'may be unable to serve as the legal basis for conducting administrative investigation by drone', and the special-compulsory-measures chapter passed in July 2024 authorises GPS, IMSI-catchers and private-space imaging with no aerial-investigation provision at all.
'Drone' appears in 19 of Taiwan's central statutes and regulations; 'counter-drone' appears in exactly one, and that one is a procurement act. Six settings are authorised to 'stop or remove' an intruding drone and none of them says by what means — Article 99-13 of the Civil Aviation Act says only 'take appropriate measures', while the 31-item police instrument list includes mortars but no jammer, and Article 67(1) of the Telecommunications Management Act has no public-duty exception.
