United Nations human rights experts have called on Iranian authorities to stop executions, raising concerns that broadly defined national security offences are being used to punish dissent and peaceful civic activity.

International concern over capital punishment in Iran has intensified as independent United Nations experts urge the authorities to reconsider the use of the death penalty, particularly in cases connected with protests and the exercise of fundamental freedoms.

The experts have warned that Iran has experienced profound human suffering, including deaths associated with armed conflict and executions carried out by the state. They argue that the country’s criminal justice system must not treat peaceful expression, assembly or other legitimate civic activities as threats deserving the harshest punishment.

Their appeal highlights wider questions about fair trials, the protection of human rights and the responsibility of governments to ensure that criminal proceedings comply with international legal standards.

UN Experts Raise Alarm Over Executions in Iran

Independent UN human rights experts have expressed concern about the continued application of capital punishment in Iran and its potential use against people accused of challenging state authority.

According to their assessment, some national security offences are defined so broadly that activities involving peaceful expression or political participation may be treated as serious criminal threats.

Such provisions can create uncertainty about the boundaries between legitimate public activity and conduct that authorities consider a security concern.

The experts have called for an immediate halt to executions and urged the Iranian government to ensure that no one is put to death in connection with the recent protest movement.

They have also stressed that allegations of criminal wrongdoing must be assessed through fair judicial procedures rather than through politically motivated prosecutions.

The appeal reflects a broader international debate over whether capital punishment can be reconciled with the protection of fundamental human rights, particularly when defendants face allegations of torture, coerced confessions or serious procedural violations.

National Security Laws Under International Scrutiny

National security legislation is intended to address threats such as espionage, terrorism and other conduct that can endanger public safety. However, human rights experts have repeatedly warned that laws framed in excessively broad terms can also be used to restrict legitimate dissent.

When legal definitions lack clarity, individuals may face serious criminal charges for conduct that should be protected under international human rights standards.

In Iran, concerns have focused on offences involving alleged cooperation with hostile states, espionage and other national security accusations.

The UN experts argue that such charges must not automatically be treated as justification for imposing the death penalty, particularly when the alleged conduct does not involve intentional killing.

International human rights law places strict limits on the use of capital punishment in countries that retain it. Under Article 6 of the International Covenant on Civil and Political Rights, the death penalty is restricted to the most serious crimes, understood by the UN Human Rights Committee as crimes of extreme gravity involving intentional killing.

The committee has stated that offences such as drug-related crimes and conduct that does not directly or intentionally result in death do not meet this threshold.

These standards have become central to international scrutiny of criminal cases in which national security allegations carry the possibility of execution.

Concerns About Fair Trials and Coerced Confessions

Another major issue identified by UN experts concerns the fairness of criminal proceedings against people arrested during protests.

The experts have raised allegations involving torture, enforced disappearances, sexual violence, coerced confessions and restrictions on access to lawyers selected by defendants.

Such allegations, where established, raise serious questions about whether convictions have been obtained through reliable evidence and lawful procedures.

A fair trial requires an independent and impartial court, access to legal representation, the opportunity to challenge evidence and protection against forced self-incrimination.

Confessions obtained through torture or other forms of coercion cannot provide a legitimate foundation for criminal punishment under international human rights standards.

The concerns are especially serious in capital cases because an execution cannot be reversed if a conviction is later found to have been wrongful.

The UN experts have therefore argued that reported procedural violations in protest-related cases must be treated as fundamental obstacles to carrying out executions.

They have called for the protection of defendants’ legal rights and for authorities to ensure that judicial proceedings meet international standards.

Protest-Related Death Sentences Draw International Attention

The treatment of people arrested during demonstrations has become a central part of the international debate over Iran’s use of the death penalty.

Human rights organisations and UN bodies have documented concerns about prosecutions linked to protest activity, including cases involving serious charges and potentially irreversible punishments.

In September 2026, the Independent International Fact-Finding Mission on Iran reported findings concerning serious human rights violations connected with protests that began in December 2025 and the subsequent period of hostilities.

The mission documented allegations and evidence involving unlawful killings, arbitrary detention, torture and violations of fair-trial rights. It also examined the use of death sentences in cases connected with the protests.

These findings have increased calls for independent investigations, accountability and stronger safeguards for people facing criminal prosecution.

The authorities’ handling of such cases remains an important test of their compliance with international human rights obligations.

The Human Cost of Capital Punishment

The debate over executions extends beyond the legal system to families, communities and society as a whole.

When a person is executed, the consequences affect relatives and dependants as well as the individual sentenced to death. Families may also experience uncertainty, social pressure and difficulties obtaining information when legal proceedings are not transparent.

The risk of wrongful execution is another fundamental concern. Errors in evidence, coerced confessions, inadequate legal representation and judicial misconduct can contribute to miscarriages of justice.

Unlike other criminal penalties, capital punishment cannot be corrected after it has been carried out.

For this reason, international human rights bodies have consistently called for strict limitations on its application and, ultimately, its abolition.

The UN experts’ intervention places particular emphasis on ensuring that individuals are not executed following proceedings compromised by serious violations of their rights.

International Law and the Death Penalty

Iran retains capital punishment in its criminal justice system, but its application remains subject to international legal obligations.

Article 6 of the International Covenant on Civil and Political Rights establishes safeguards concerning the right to life and limits the circumstances in which the death penalty may be imposed.

Article 14 addresses fair-trial protections, including the right to a competent, independent and impartial tribunal and essential guarantees for people facing criminal charges.

The prohibition against torture is also fundamental. Evidence obtained through torture cannot lawfully be used as a basis for convictions, except in proceedings against alleged perpetrators of torture for the purpose of establishing that torture occurred.

These protections are especially important when national security allegations are used in cases that could result in execution.

Human rights experts argue that states must distinguish between genuine criminal conduct and peaceful activities protected by international law.

They also emphasise that security concerns cannot remove a government’s responsibility to protect the right to life and ensure access to justice.

Calls for an Immediate Halt to Executions

The independent experts’ appeal places the immediate future of people facing execution at the centre of the discussion.

They have urged Iranian authorities to halt executions, particularly those involving individuals prosecuted in connection with protests.

A suspension of executions would prevent irreversible punishment while cases are reviewed and concerns about procedural violations are examined.

It would also create an opportunity to assess whether national security legislation and judicial practices are consistent with international human rights obligations.

Further steps could include ensuring access to independent legal representation, investigating allegations of torture, reviewing death sentences and providing transparent information about judicial proceedings.

Independent monitoring would also be important for establishing whether reported abuses are investigated effectively and whether those responsible are held accountable.

Why the Issue Matters Beyond Iran

The controversy surrounding Iran’s use of capital punishment raises broader questions about the relationship between national security, public protest and individual rights.

Governments have a responsibility to protect public safety, but that responsibility does not eliminate the right of people to express opinions, assemble peacefully or participate in public affairs.

When security legislation is applied too broadly, legitimate civic activity can become vulnerable to criminal prosecution.

International human rights standards are designed to establish limits on state power while allowing lawful responses to genuine threats.

The issue is also significant for the credibility of judicial institutions. Public confidence in justice depends on transparent procedures, reliable evidence, independent courts and the ability of defendants to challenge allegations against them.

Ensuring these safeguards is particularly important in cases involving punishments that cannot be reversed.

The Road Ahead

The UN experts’ warning places renewed international attention on the protection of life, the independence of judicial proceedings and the treatment of people arrested during protests in Iran.

Their central demand is that executions be halted and that criminal cases be assessed in accordance with international human rights standards.

The wider challenge is to ensure that national security laws are clearly defined, peaceful dissent is not treated as a capital offence and allegations of serious procedural misconduct receive independent investigation.

Any meaningful improvement will require transparent judicial processes, access to legal representation and effective safeguards against torture and coerced confessions.

For the international community, the situation remains an important test of efforts to protect fundamental freedoms and uphold the right to life.

The experts’ message is clear: allegations of criminal wrongdoing must be addressed through lawful and fair proceedings, and the use of the death penalty must never become a means of silencing peaceful dissent.
