Informed Consent Vs Invalid Consent

A Case sudy of forced sterilization of women living with HIV in Kenya.

Informed consent is not a signature, it is understanding plus freedom of choice. This case study shows how women living with HIV were coerced into irreversible sterilization, and how the law distinguishes informed consent from invalid consent in clinical settings.

Informed Consent Vs Invalid Consent

Ezekiel Munyua

Article Overview

This insight examines the doctrine of informed consent through two constitutional petitions involving women living with HIV who alleged they were coerced into tubal ligation, an irreversible sterilisation procedure, after presenting for antenatal care. It explains what informed consent requires in law, then applies Kenya’s statutory framework under the Health Act, 2017 and related patient rights instruments to show why consent obtained through coercion, manipulation, or without genuine understanding is invalid. 

The piece highlights how vulnerability, stigma, language barriers, and power imbalance between patients and healthcare providers can erode autonomy, and it underscores the duty on healthcare providers to provide adequate information in a language understood by the patient before any non-emergency procedure is performed.

Key takeaways

  • Case study basis: the analysis is grounded in L.A.W. & 2 others v Marura Maternity & Nursing Home & 3 others (Petition E606 of 2014) and S.W.K. & 5 Others v Médecins Sans Frontières & 5 Others (Petition E605 of 2014), decided on 16 December 2022 and 21 September 2023 respectively.
  • Meaning of informed consent: valid consent requires full authorisation by an autonomous person, given intentionally, with adequate information, and free from controlling influence or duress.
  • Legal duties under the Health Act: Section 8 requires disclosure of available options, benefits, risks, costs, consequences, and the right to refuse, plus implications of refusal.
  • Limited exceptions to consent: Section 9 recognises exceptions such as emergencies, court orders, public health concerns, risk of death or irreversible injury, or incapacity, with substitute consent rules where applicable.
  • Patient rights standards: the Kenya National Patients’ Rights Charter (2013) emphasises full, accurate information in a language the patient understands, with decisions made willingly and free from duress except in emergencies.
  • Sterilisation safeguards: FIGO guidance is referenced as requiring absence of coercion, pressure, or undue inducement, and the provision of information in a language understood.
  • Why consent was found invalid in the petitions: the article notes coercion linked to HIV status and vulnerability, including semi-illiteracy, inability to understand documents, and inducement through essentials such as formula milk and supplements.
  • Three elements of valid consent: voluntariness, understanding, and absence of undue influence, with undue influence categorised as persuasion, coercion, and manipulation.
  • Conclusion: consent is central to dignity and self-determination; the burden lies on healthcare providers to explain risks, benefits, and alternatives before treatment.
