Vaccination policy and proportionality: courts defer to experts, but restrictions on unvaccinated persons must still satisfy constitutional review.

A vaccination policy affecting fundamental rights is subject to judicial review for legality, reasonableness and manifest arbitrariness, even though courts generally defer to executive and expert public-health judgment. Bodily integrity and personal autonomy under Article 21 mean vaccination cannot be physically compelled, and restrictions on unvaccinated persons must satisfy a legitimate public health aim and proportionality. The text also states that trial results and required future data should be published under the clinical-trial framework, but segregated primary trial data need not be disclosed absent a legal mandate. It further notes that adverse-event reporting systems should permit wider self-reporting and that paediatric vaccination policy is ordinarily left to expert consensus.

Issues: (i) maintainability of the public interest petition; (ii) scope of judicial review over vaccination policy based on expert opinion; (iii) whether vaccine mandates restricting access for unvaccinated persons were proportionate; (iv) whether segregated clinical trial data and regulatory material had to be disclosed in public domain; (v) whether the AEFI surveillance and reporting system was deficient; and (vi) whether the policy on vaccination of children called for interference.

Issue (i): maintainability of the public interest petition

Analysis: The petitioner was not a stranger to the subject and raised questions bearing on public health and fundamental rights. A public interest petition may be entertained where the petitioner has subject-matter knowledge and the issues warrant judicial scrutiny rather than summary rejection on the apprehension that the petition may create vaccine hesitancy.

Conclusion: The challenge to maintainability failed and the petition was held maintainable.

Issue (ii): scope of judicial review over vaccination policy based on expert opinion

Analysis: Policy choices in matters of public health ordinarily lie within the executive domain and courts do not sit in appeal over scientific assessments. Yet judicial review remains available where the policy is unconstitutional, arbitrary, unreasonable, or contrary to statute, and where fundamental rights are implicated. The governing standard is not substitution of judicial views for expert judgment, but scrutiny for legality, reasonableness and manifest arbitrariness.

Conclusion: The Court held that wide latitude is due to the executive, subject to constitutional review on settled grounds.

Issue (iii): whether vaccine mandates restricting access for unvaccinated persons were proportionate

Analysis: Bodily integrity and personal autonomy are protected facets of Article 21, and no person can be physically forced to be vaccinated. However, limitations affecting unvaccinated persons may still be justified where they satisfy legality, legitimate State aim and proportionality. On the material then before the Court, vaccination policy itself was upheld as informed by public health considerations, but no adequate material was shown to justify differential restrictions only against unvaccinated persons once the evidence indicated that transmission risk from vaccinated and unvaccinated persons had become broadly similar. The restrictions therefore failed the proportionality standard in the then-prevailing circumstances.

Conclusion: Vaccine mandates imposing discriminatory restrictions on unvaccinated persons were held disproportionate in the prevailing situation, though the executive's lawful power to impose future restrictions was left open.

Issue (iv): whether segregated clinical trial data and regulatory material had to be disclosed in public domain

Analysis: The statutory framework under the New Drugs and Clinical Trials Rules, 2019, together with the Good Clinical Practices guidelines and the ethical principle of privacy and confidentiality, required publication of trial results and key outcomes, but did not justify a direction for disclosure of primary clinical trial data in the absence of a legal mandate. The Court found that the approval process for the vaccines had been conducted through expert bodies, that the relevant minutes and outcomes were available in public domain, and that there was material compliance with the governing regime. At the same time, ongoing and future trial data required publication without undue delay to the extent permitted by the governing rules and privacy protections.

Conclusion: No direction was issued to disclose segregated primary clinical trial data, but publication of required future data was directed.

Issue (v): whether the AEFI surveillance and reporting system was deficient

Analysis: The Court accepted that a structured surveillance framework existed for reporting, investigation and causality assessment of adverse events following immunisation. The broad allegation that the system was faulty or opaque was not accepted. However, wider participation in reporting was considered necessary for better data collection and public awareness, and the Court directed that suspected adverse events should also be capable of being reported by individuals and private doctors on a virtual platform with public accessibility and anonymisation safeguards.

Conclusion: The challenge to the surveillance system failed, but a direction was issued to enable self-reporting by individuals and private doctors.

Issue (vi): whether the policy on vaccination of children called for interference

Analysis: The decision to vaccinate children was treated as a policy matter supported by global and domestic expert consensus. The Court declined to second-guess scientific opinion on paediatric vaccination. However, consistent with the governing trial-disclosure framework, the Court directed publication of the key findings and results of the relevant clinical trials for paediatric vaccines already approved for use.

Conclusion: The challenge to paediatric vaccination was rejected, with a direction to publish the relevant trial findings and results.

Final Conclusion: The petition was disposed of with limited reliefs: the general vaccination policy was upheld, discriminatory unvaccinated-only restrictions were found unsustainable on the record then available, and directions were issued for greater transparency in adverse-event reporting and publication of mandated trial results.

Ratio Decidendi: A vaccination policy affecting fundamental rights is valid only if it satisfies legality, a legitimate public health aim and proportionality; while courts defer to expert policy choices, they may intervene where restrictions on autonomy or equality are not shown to be justified on the material before them.
