Search litigation on the Judicial Yuan judgment system by company name; check the procurement blacklist on the government e-procurement “refused dealings” list; also check labor-violation and environmental-penalty lists. All public and free.
The judgment system holds rulings from all court levels — but judgments must not be aggregated into an identifiable individual’s record (PDPA).
Being listed as a “refused-dealings” vendor signals serious performance failure or violation — an important negative signal.
The Ministry of Labor publishes wage/overtime/safety violators; the Ministry of Environment publishes penalties — worth checking before contracting.
Open Company DD →Yes, but for verification only — do not aggregate into identifiable individuals.
Lawsuit counts are not automatic. Four checks are: government tender count, procurement blacklist (refused dealings), Ministry of Environment penalties, and Ministry of Labor penalties. The first three match precisely by unified business number; the labor one matches by company name, so same-name false positives are possible and “no match” does not mean clean. Court judgments stay a one-click official link — automatic aggregation would be inappropriate under the PDPA.
