UN Human Rights Council Adopts Resolution on Iran Amid Express Reservations by the United Kingdom Regarding Mandate and Scope

Geneva — On 25 March 2026, during its 61st session, the United Nations Human Rights Council adopted, without a vote, resolution A/HRC/61/L.38 as orally revised. The full text of the resolution is accessible here:https://docs.un.org/A/HRC/61/L.38

The text, introduced by members of the Gulf Cooperation Council and Jordan, addresses the human rights implications of events of 28 February 2026 involving the Islamic Republic of Iran and several States in the Gulf region. The urgent debate preceding the adoption is publicly available via United Nations Web TV:https://webtv.un.org/en/asset/k1a/k1az12eff6

The resolution condemns actions attributed to Iran, characterising them as violations of international law and as posing risks to regional stability. It calls for cessation of hostilities, invokes compliance with United Nations Security Council resolution 2817 (2026), and refers to the provision of reparation to affected individuals. It further highlights concerns relating to civilian harm, infrastructure damage, and the potential impact on international navigation and economic stability.

While the adoption by consensus reflects broad political alignment among sponsoring States, the process and substance of the resolution raise questions regarding balance, scope, and institutional competence. The text presents the events of 28 February 2026 in a manner that focuses primarily on actions attributed to Iran, without detailed reference to preceding developments that may be relevant to a comprehensive legal assessment. This approach may affect the ability of the Council to undertake a fully contextual and impartial evaluation, particularly where the legal characterisation of conduct depends on the sequence of events.

In this regard, international law requires that any assessment of the use of force be conducted with due regard to the full factual context. The International Court of Justice has consistently affirmed that the right of self-defence under Article 51 of the Charter of the United Nations is triggered only in response to an armed attack of sufficient “scale and effects,” as established in Military and Paramilitary Activities in and against Nicaragua (Judgment of 27 June 1986, paras. 176, 193–195). Subsequent jurisprudence, including Oil Platforms (Judgment of 6 November 2003, paras. 51, 73–78) and Armed Activities on the Territory of the Congo (Judgment of 19 December 2005, paras. 147, 165), has reaffirmed that any invocation of self-defence must satisfy the requirements of necessity and proportionality and must be assessed in light of the circumstances giving rise to the alleged armed attack.

The omission of contextual elements, particularly where allegations of prior use of force exist, may therefore affect the legal characterisation of subsequent conduct and the overall integrity of the analysis. A comprehensive assessment requires consideration of all relevant acts, including those that may constitute the initiating use of force, as well as their legal implications under the Charter.

A notable feature of the adoption was the explanation of position delivered by the United Kingdom. While co-sponsoring the resolution and expressing concern regarding regional stability and civilian protection, the United Kingdom placed several reservations on record concerning the scope of the Human Rights Council’s mandate. It emphasised that the determination of inter-State reparations falls outside the Council’s competence and that the characterisation of situations as threats to international peace and security lies within the exclusive authority of the Security Council. It further clarified that its interpretation of the resolution was limited to reflecting determinations already made by the Security Council in resolution 2817 (2026), rather than establishing new findings within the Human Rights Council framework.

The United Kingdom also reiterated established positions regarding the territorial scope of human rights obligations and the interpretation of the United Nations Convention on the Law of the Sea. Importantly, it underscored that its support for the resolution should not be regarded as acceptance of the text as a precedent for future practice, thereby signalling caution with respect to potential institutional overreach.

These reservations are legally significant. They reflect a concern that the Human Rights Council may be engaging with issues that extend beyond its primary mandate, particularly in areas traditionally reserved for the Security Council, including determinations related to peace and security, the use of force, and inter-State responsibility. Such concerns highlight the importance of maintaining clear institutional boundaries within the United Nations system.

From a broader legal perspective, the situation also engages the obligation of due diligence under customary international law. As articulated by the International Court of Justice in Corfu Channel (Judgment of 9 April 1949, p. 22), States are under an obligation not to allow knowingly their territory to be used for acts contrary to the rights of other States. This principle has been reaffirmed in Nicaragua (1986) and further elaborated in Armed Activities (2005), where the Court emphasised the responsibility of States to prevent the use of their territory for unlawful armed activities.

The interaction between the right of self-defence and the obligation of due diligence is particularly relevant in situations involving multiple actors and complex operational environments. Where territory, airspace, or infrastructure of a State is used as part of an armed attack, and where that State fails to take reasonable measures to prevent such use despite knowledge and capacity, questions may arise regarding its responsibility under international law. In such circumstances, the legal assessment of defensive measures must take into account both the requirements of necessity and proportionality and the broader factual matrix in which the events occur.

In this context, the assessment of the events of 28 February 2026 necessitates careful consideration of all relevant legal and factual elements, including any preceding acts of force, the conduct of all parties involved, and the role of third States. A comprehensive approach is essential to ensure that international legal standards are applied consistently and without selectivity.

The adoption of the resolution without a vote, notwithstanding expressed reservations by a co-sponsoring State, illustrates the extent to which political consensus may coexist with legal divergence. While consensus adoption may reflect diplomatic pragmatism, it does not eliminate underlying differences regarding interpretation, mandate, and precedent.

For the Human Rights Council, the present case underscores the importance of preserving its role as a forum for objective and balanced examination of human rights situations. The credibility of the Council depends on its ability to apply international law in a consistent and non-selective manner, taking into account the full context of complex situations involving the use of force and their human rights implications.

Justice Pour Tous Internationale recalls that the universality and equal application of international law remain essential to the integrity of the international system. Ensuring that legal standards are applied consistently, that institutional mandates are respected, and that all relevant facts are duly considered is fundamental to promoting accountability, preventing escalation, and maintaining confidence in multilateral human rights mechanisms.
