Taiwan's Constitutional Court has partially invalidated stiff penalties for late supplementary National Health Insurance payments, but the decision—issued by a bare five-justice majority amid ongoing vacancies—has sparked sharp criticism over its own procedural validity and raised alarms about judicial overreach.
The ruling,Constitutional Judgment No. 2 of 2026, stemmed from a construction contractor penalized NT$90,000 (three times the NT$30,000 owed) after ignoring overdue notices. The majority found the law's fixed one- to three-fold multiplier excessively harsh, breaching proportionality and property rights, and ordered amendments within two years. Until then, authorities may set flexible fines based on circumstances, potentially creating uneven enforcement.
Yet the judgment's legitimacy is contested. With vacancies unfilled since late 2024—despite repeated nomination deadlocks between President Lai Ching-te (賴清德) and the legislature—the court operates with only eight justices. Three declined to join deliberations, arguing the case required at least a two-thirds quorum (10 justices) under constitutional litigation rules for valid acceptance. They issued separate opinions rejecting both the substance and the court's authority to rule, warning that such short-handed decisions risk invalidation in the future.
Substantively, the majority's reasoning draws scrutiny. Multiplier penalties are routine in Taiwan's fiscal framework, appearing in income tax, customs, securities, land, and business tax laws to deter evasion—without them, non-payment could become incentivized. Supplementary premiums, capped and at lower rates than regular contributions, target higher earners (e.g., via stock dividends) in a system long debated as more tax-like than insurance-based. If triple fines here violate proportionality, critics ask why similar deterrents elsewhere remain constitutional. Earlier interpretations, such as No. 673 on withholding failures equating to evasion, supported equivalent punishments, highlighting potential inconsistency.
Justice Lu Tai-lang (呂太郎), in a concurring opinion, invoked constitutional flexibility for implementation laws, but opponents view this as judicial overstep, noting the framers placed the judiciary below the executive and legislature in hierarchy—never envisioning courts unbound by procedural norms or full composition.
The broader fallout looms large. National Health Insurance faces chronic funding pressures, with past reform efforts stalled. This ruling may encourage delays in payment or complicate amendments, while persistent vacancies could lead to more disputed verdicts, eroding public confidence in institutions amid cross-strait and regional challenges.
Taiwan's experience underscores a universal constitutional truth: judicial authority rests on both sound reasoning and impeccable process. When a court's own members challenge its composition, the damage transcends one case—undermining governance stability in any democracy governed by the rule of law. Swift resolution of vacancies remains essential to restore balance.
