Scope of “Minimal Risk” Classification Disputes

Introduction

“Minimal risk” classification is a research-ethics standard used to determine whether a proposed study exposes participants to risks no greater than those ordinarily encountered in daily life or during routine examinations. It is important in biomedical research, biotechnology, behavioural studies, health-data analysis, and clinical investigations.

A dispute arises when researchers, sponsors, or ethics committees disagree about whether a study is genuinely minimal risk. The classification matters because it may determine the level of ethics review, consent requirements, monitoring, and additional safeguards. However, minimal risk does not mean zero risk, and a study cannot be classified as minimal risk merely because it is inexpensive, non-invasive, or scientifically valuable.

In India, the classification is addressed through research-ethics guidelines and institutional ethics committee review. The legal framework must protect participants while allowing low-risk research to proceed without unnecessary regulatory burden.

Indian Ethical and Regulatory Standards

The ICMR National Ethical Guidelines for Biomedical and Health Research Involving Human Participants (2017) recognize four risk categories: less than minimal risk, minimal risk, minor increase over minimal risk, and more than minimal risk. They describe minimal risk by comparing anticipated harm or discomfort with ordinary daily-life activities or routine tests. Examples may include routine questioning, observation, physical examination, or collection of non-invasive samples.

A key rule is that the researcher cannot unilaterally decide that a proposal is minimal risk or exempt. The Ethics Committee (EC) must determine the appropriate review category. A proposal may be eligible for expedited review, but studies involving vulnerable participants, deception, altered risk, or significant protocol changes may require full committee review.

Disputes often arise because risk is not limited to physical harm. Confidentiality breaches, genetic discrimination, psychological distress, social stigma, and economic consequences can also affect classification. Ethical review must consider these indirect harms, as well as the probability and severity of possible injury.

Case Laws

There is no well-established Indian Supreme Court judgment specifically deciding a dispute over “minimal risk” classification. The following cases provide related legal principles concerning research participants’ autonomy, privacy, and informed consent.

1. Samira Kohli v. Dr. Prabha Manchanda (2008) 2 SCC 1

The Supreme Court held that valid medical consent must be voluntary and based on adequate information about the proposed intervention. The case concerned medical treatment rather than research-risk classification, but its principles are relevant where an ethics committee classifies a research procedure as minimal risk. A low-risk classification cannot by itself eliminate the need for appropriate consent or justify an intervention outside the consent given.

2. Justice K.S. Puttaswamy (Retd.) v. Union of India (2017) 10 SCC 1

The Supreme Court recognized privacy as a fundamental right under Article 21 and the freedoms in Part III. The judgment emphasized autonomy, dignity, and informational privacy. This is relevant where a study uses identifiable health records, genomic information, or sensitive personal data. Even if physical procedures are minimal, a risk of privacy invasion or data misuse may require additional safeguards and may affect the ethics committee’s classification.

3. Jacob Mathew v. State of Punjab (2005) 6 SCC 1

The Supreme Court explained that professional negligence requires a failure to exercise reasonable skill and care, and that an adverse outcome alone does not establish negligence. Applied by analogy, a dispute over risk classification should be assessed using the information and professional standards reasonably available when the ethics committee made its decision. A later adverse event does not automatically prove that the original classification was negligent, although failure to respond to emerging evidence may raise further issues.

Scope of Disputes and Conclusion

Minimal-risk disputes may involve:

Whether the procedure creates physical, psychological, social, or informational harm.

Whether the comparison is with ordinary daily life or routine medical examinations.

Whether vulnerable participants require heightened scrutiny.

Whether identifiable data or biospecimens create privacy or discrimination risks.

Whether a protocol amendment or new adverse event changes the risk level.

The ICMR framework requires Ethics Committees to make the classification on a case-by-case basis. Researchers may request a particular review category, but cannot determine it independently. Full review may be required where vulnerability, deception, protocol changes, or newly identified risks materially alter the assessment.

In conclusion, minimal-risk classification is an ethical and regulatory judgment, not a blanket exemption from participant protection. Indian law requires careful assessment of foreseeable harms, privacy, consent, and the characteristics of the research population. The relevant case law supports autonomy, confidentiality, and professional care, though the cited judgments are analogous rather than direct rulings on minimal-risk classification disputes.
