Former Taiwan People's Party legislator Li Chen-hsiu has announced a run for mayor of Zhubei City in Hsinchu County, but her candidacy is almost certain to be blocked — bad news for her personally, and a key step for those who want to see the dispute over political participation by Chinese spouses reach the courts.

• Li Chen-hsiu announced her entry into the 2026 Zhubei mayoral race on a platform of transport, education and environmental policies.
• The Central Election Commission set its position in July this year: former Chinese nationals must have held household registration in Taiwan for a full 10 years, counted from the date they submit proof of renunciation of their original nationality, before they are eligible to run.
• Li did not file the supplementary documents until March 2025, so under that method of calculation she would be ruled ineligible once she registers.
• She had previously taken up a party-list legislative seat, but the Ministry of the Interior questioned whether her status as a Chinese spouse breached the Nationality Act, the TPP expelled her from the party, and the Taipei High Administrative Court dismissed her administrative litigation.
• This run is being read not as a bombshell but as an attempt to open the door to subsequent court proceedings.

Outlook: Once the registration period arrives, Li Chen-hsiu will most likely be excluded by the Central Election Commission, and the real battleground will shift to the courts.
