The Coronavirus Act 2020 and Civil Liberties: A Critical Examination

Unprecedented powers and the role of Schedule 21

The government introduced a range of powers to control the spread of COVID‑19. Among the most significant are those contained in Schedule 21 of the Coronavirus Act 2020 (Coronavirus Act), which grants public health officers, supported by police and immigration officers, authority to direct, remove, detain and assess individuals believed to be potentially infectious.

These powers are unprecedented in peacetime. Although the severity of COVID‑19 justified exceptional measures, it remains vital to scrutinise how far these restrictions extend and whether they adequately protect constitutional principles such as access to justice and proportionality.

Former Supreme Court Justice Lord Sumption publicly warned that the UK risked drifting towards a “police state” if enforcement exceeded legal authority. His comments reflected wider concerns about the breadth of emergency powers and the speed at which they were enacted.

Isolation and the Public Health (Control of Disease) Act 1984

Professor Jeff King of UCL argued early in the pandemic that the Regulations were lawful and did not amount to true quarantine. Under the Public Health (Control of Disease) Act 1984 (1984 Act), ministers may impose “special restrictions,” but section 45G(2)(d) prohibits regulations requiring a person to be kept in isolation or quarantine.

The national lockdown, however, was imposed under the Health Protection (Coronavirus, Restrictions) (England) Regulations 2020, made under section 45C of the 1984 Act, which permits restrictions on movement. Because individuals retained limited lawful reasons to leave home, the restrictions did not constitute mandatory isolation within the meaning of section 45G.

This distinction highlights the complexity of the legislative framework and the importance of understanding which statutory powers were used to impose specific restrictions.

Medical testing and biological samples

Section 45G(2)(a) of the 1984 Act prohibits regulations requiring individuals to undergo medical examination. The Coronavirus Act, however, is primary legislation and therefore capable of overriding this safeguard.

Schedule 21, paragraph 20(4) permits a public health officer, with police assistance if necessary, to take a biological sample using reasonable force. This represents a significant departure from previous public health powers and raises concerns about bodily autonomy, consent and proportionality.

Questions also arise regarding the retention and use of biological samples. In 2019, the European Court of Human Rights held that indefinite retention of personal data by police without adequate safeguards breached Article 8. Although the circumstances differ, the judgment underscores the need for clear limits and protections when collecting sensitive personal information.

Individuals lacking mental capacity

The Mental Capacity Act 2005 (MCA 2005) provides a framework for decision‑making on behalf of individuals who lack capacity. Schedule 21 does not explicitly address how its powers should be applied to individuals who cannot understand or comply with directions due to impaired capacity.

While the MCA 2005 continues to apply, the absence of specific provisions creates uncertainty for public health officers, police and carers. Emergency powers must be workable for all individuals, including those who rely on statutory protections to ensure their rights are upheld.

Constitutional concerns and access to justice

The UK constitution relies on checks and balances between branches of state. Although Schedule 21 includes an appeal mechanism, it does not explicitly provide for legal representation or allow a representative to initiate an appeal on behalf of an affected person. This gap raises concerns about access to justice, particularly for vulnerable individuals.

Emergency legislation must remain subject to scrutiny, even during a crisis. The breadth of powers in the Coronavirus Act requires careful monitoring to ensure they do not extend beyond what is necessary and proportionate.

Conclusion

COVID‑19 demanded swift and decisive action, and few would dispute the need for temporary restrictions to protect public health. However, some provisions of the Coronavirus Act, particularly those permitting the use of reasonable force to obtain biological samples, represent a significant expansion of state power.

Clear guidance is needed on the retention of biological samples, the treatment of individuals lacking mental capacity and the practical operation of appeal rights. These issues must be addressed to ensure that emergency powers remain compatible with constitutional principles and fundamental liberties.

The pandemic has tested the limits of public health law. As the UK continues to navigate its response, temporary measures mustn't become permanent incursions into civil liberty.
