Are Netanyahu and Gallant immune from ICC arrest warrants under international law?

The short answer is no. But states have previously flouted their obligations to surrender leaders like Vladimir Putin and Omar al-Bashir to the ICC by invoking immunity

Israeli Prime Minister Benjamin Netanyahu and his former defence minister, Yoav Gallant, are now wanted persons under international law, after the International Criminal Court issued arrest warrants for them on Thursday.

All 124 state parties to the Rome Statute, including all EU members, are now under a legal obligation to arrest the pair and surrender them to the court. A trial cannot commence in absentia, and the court has no enforcement powers.  

It is likely, however, that Israeli leaders will argue that they are entitled to immunity from arrest and surrender to The Hague on the basis that Israel is not party to the treaty.

Additionally, state parties to the Rome Statute may take advantage of loopholes in the treaty to refuse to arrest and surrender Netanyahu, as was the case with states that failed to arrest Sudan’s Omar al-Bashir or Russia’s Vladimir Putin, both wanted by the court.  

"An immunity defence will undoubtedly be mounted,” Professor Leila Sadat, a leading expert on immunities and former ICC special advisor on crimes against humanity, told Middle East Eye. But she added that ICC judgments in the past have already foreclosed that avenue.

Officials of all ranks, including a head of state or government, under an ICC arrest warrant are not entitled to immunity, even if they belong to a non-state party to the Rome Statute. 

The arrest warrants are part of a war-crimes investigation on the situation in Palestine, launched in 2021 by the former ICC prosecutor. 

While Israel is not a member of the ICC, the State of Palestine was granted membership in 2015. Accordingly, the court can investigate Israeli nationals for crimes committed in occupied Palestine, which includes the Gaza Strip, the West Bank and East Jerusalem. 

Below, Middle East Eye unpacks immunity rules under international law generally and as stipulated in the Rome Statute, and why they are likely to be used in arguments seeking to protect Netanyahu, Gallant or other Israeli state officials from prosecution.   

What types of immunity exist under international law?

There is no treaty enshrining immunity rules under international law, but such rules can be derived from state practice, court judgements and scholarly opinion. 

A state official facing charges of serious international crimes like war crimes, crimes against humanity and genocide can invoke two types of immunity before national or international courts.

First, they may claim that they are entitled to functional immunity, which permanently shields them from prosecution for acts carried out in their official capacity as state actors.

This protection, theoretically, applies during and after they leave office. It benefits officials of all ranks. However, the international criminal law jurisprudence that followed World War II has introduced an exception to this rule in relation to serious international crimes. 

The Nuremberg trials, the ad hoc tribunals of the former Yugoslavia and Rwanda, as well as the Rome Statute have permanently challenged the rationale for this type of immunity by enshrining the concept of individual criminal responsibility and the irrelevance of official capacity in cases of allegations of international crimes.

This also appears to be the position of the International Law Commission, the UN’s main body of experts tasked with the development and codification of international law.

The second type of immunity, known as personal immunity, is more controversial and might be used by states either to refuse to arrest and surrender Israeli leaders to the ICC or protect them from prosecution before their national courts.

Personal immunity protects heads of state, prime ministers and foreign ministers from prosecution during their time in office in order to preserve the smooth functioning of international relations and the officials' unhindered ability to perform their duties, including the representation of their state internationally. 

Personal immunity is a procedural rule that applies when the officials are present on the territory of another state in an official capacity. 

'No international court has ever found that a head of state or high ranking individual has immunity before it, and Article 27 was meant to codify that principle'

- Professor Leila Sadat

In the case of Netanyahu, such immunity may protect him when he travels to states that are not party to the Rome Statute if these states have universal jurisdiction on international crimes, such as the United States. 

Universal jurisdiction is a legal principle that allows a state to prosecute people for serious international crimes, regardless of where the crime was committed or the nationality of the victim or perpetrator.

The above types of immunity, however, are widely understood to be inapplicable in the case of an arrest warrant issued by the ICC. This is because it is uncontroversial that state officials of all ranks have no immunity before an international court with jurisdiction, such as the ICC.  

It is the raison d’etre of the Rome Statute to hold individuals accountable for the four crimes under its jurisdiction - genocide, war crimes, crimes against humanity and aggression - without regard to their official capacity as state officials or leaders.

But there are obstacles and loopholes that might arise in the case of nationals of states that are not party to the ICC, such as Netanyahu, as explained below.

Is Netanyahu immune under the Rome Statute?

The rules on immunity are stipulated in Articles 27 and 98 of the Rome Statute

Article 27 clearly states that all wanted persons are equal before the court, including heads of a state or government. No immunities under international law may bar the court from exercising its jurisdiction, it adds. 

The main loophole in the statute, however, is a provision in Article 98 (1) that introduces an exception to Article 27 in relation to the arrest and surrender of officials from states that are not members of the ICC, such as Israel. 

It stipulates that the court may not request the arrest of a non-ICC country's official if that would force a member of the ICC to act inconsistently with its international law obligations on state or diplomatic immunity. The country that official belongs to must waive their international immunity to proceed.

“On the face of it, this rule would apply to Netanyahu, who enjoys immunities under international law as head of government of Israel,” said Paola Gaeta, professor of international law at the Geneva Graduate Institute and prominent expert on immunities.

But, as Professor Sadat has noted, the ICC Appeals Chamber's judgment of 6 May 2019 in Al Bashir case has clearly argued that there is no immunity at all for a head of state before an international court with jurisdiction, as opposed to a national court. Article 98 (1), as the court noted and as she explained, must be read in context and interpreted in a manner that is consistent with the object and purpose of the Rome Statute, meaning that it should not be read to carve out an exception to Article 27’s clear provisions.

"No international court has ever found that a head of state or high ranking individual has immunity before it, and Article 27 was meant to codify that principle," she added.

At any case, Israel could still choose to surrender Netanyahu to the ICC, though that appears extremely unlikely while he is prime minister.

Moreover, states that are not members of the Rome Statute may choose to surrender the suspects to The Hague, bar them from entering their territories, or prosecute them under their domestic jurisdictions. 

The immunity rule does not apply to Gallant, who is no longer in office, as former state officials do not enjoy the same immunities as serving officials. Netanyahu would similarly no longer be entitled to any immunity for international crimes after leaving office. A future Israeli government may hand them over to The Hague. 

For now, as a precaution, Netanyahu and Gallant will have to restrict their travel, as Putin did following the ICC arrest warrant against him. 

How have ICC members flouted their obligations to arrest state leaders?

Article 98 (1) has been used in the past by states that refused to hand over Bashir and Putin, who are nationals of states not party to the ICC. 

For example, Jordan triggered Article 98 (1) when it did not arrest Bashir on 29 March 2017, and Mongolia refused to arrest Putin when he visited the country on 3 September 2024, saying he enjoys both functional and personal immunity.

But the ICC in the two cases rejected the immunity plea as unfounded. Last month, the court ruled that Mongolia had violated the Rome Statute by failing to arrest Putin. 

In explaining its rationale, the court said the article “refers only to acts of government activities which are typically conducted abroad and are protected by the safeguards on diplomatic immunity for certain officials and buildings”.

It added that the reference to state immunity under article 98 (1) is related to the immunity of a state and its property, not its leaders or officials.

“It is reasonable to expect the pre-trial chamber to take a similar position with regard to Netanyahu and Gallant,” said William Schabas, a prominent international criminal law professor and scholar.

Professor Sadat agrees, explaining that the purpose of Article 98 (1), at the time of drafting, was "to address interstate issues such as the inviolability of diplomatic correspondence, embassies, etc."

On the other hand, Professor Gaeta explained that when the ICC rejected the claim of Jordan and other states that refused to arrest Bashir, it did so on the basis that the United Nations Security Council had referred the situation in Sudan's Darfur to the court. Such referral, the court held, prevailed over Article 98 (1).

“This argument is not available to the case of Netanyahu, since the jurisdiction of the court over the crimes in Gaza was not triggered by the Security Council,” said Gaeta. 

But Sadat said the immunity still applies regardless of the nature of the referral. The rationale of the court would apply in the Netanyahu case as well, she added.

The court emphatically said that immunities for officials of non-ICC member states did not apply in Bashir's case. 

'The heads of states do not enjoy immunity before the ICC, period, irrespective of whether they belong to state parties or also to non-party states'

Giulia Pinzauti, international law professor Leiden university

“In the end, I guess that the case of Netanyahu will reopen the debate that was apparently settled in the case of Bashir,” Gaeta said. 

Giulia Pinzauti, an international law professor at Leiden university, noted that Mongolia has sought to appeal the ICC’s decision on its non-compliance.

“We haven't had a final word on this,” said Pinzauti. “On the other hand, you also have statements like the one by the Dutch foreign minister that stated that the Netherlands will arrest the suspects if they enter Dutch soil,” she added.

“So this is a very important statement for state practice. It reinforces the view that is gaining ground among states. The heads of states do not enjoy immunity before the ICC, period, irrespective of whether they belong to state parties or also to non-party states.”

If states do not comply with the court’s request for arrest, their conduct will be referred to the Assembly of States Parties, the governing body of the ICC, as was the case with Mongolia.

Then the assembly can take measures to induce cooperation.
