Israel's Knesset Passes Law Establishing Military Tribunal to Prosecute October 7 Perpetrators

Israel's parliament voted 93–0 on May 11, 2026 to establish a dedicated military tribunal empowered to try hundreds of Hamas militants for crimes committed during the October 7, 2023 attack — and, for the first time in more than six decades, to sentence defendants to death [1][2]. The legislation, titled the "Prosecution Law for the October 7 Massacre," passed with rare bipartisan consensus across Prime Minister Benjamin Netanyahu's governing coalition and much of the opposition, with 27 lawmakers absent or abstaining [3].

The law creates a new institution within Israel's military justice system unlike anything the country has operated before: a public, televised war crimes tribunal seated in Jerusalem, staffed by civilian-caliber judges, and authorized to prosecute charges ranging from genocide and crimes against humanity to murder, rape, hostage-taking, and looting [1][4]. Its passage sets up one of the most consequential legal proceedings in Israeli history — and one of the most contested.

Who Will Be Tried

The tribunal's jurisdiction covers an estimated 300 to 400 Palestinian fighters captured by Israeli security forces inside Israel during the October 7 assault, the majority of them members of Hamas's elite Nukhba Force [2][5]. The exact breakdown by organizational affiliation — Hamas operatives, Palestinian Islamic Jihad members, and civilians who joined the attack — remains classified by the Shin Bet security agency [6].

The tribunal can also prosecute individuals captured later during the war in Gaza who are suspected of participating in the October 7 attack or of having held or abused Israeli hostages in captivity [5]. Prosecutors are assembling case files from forensic evidence, interrogation transcripts, and footage [5].

These figures are separate from the broader population of Palestinian detainees held by Israel. As of early 2025, the Israel Prison Service reported approximately 2,300 detainees arrested in connection with October 7, and nearly 10,000 Palestinian prisoners held in total [6]. The tribunal law applies specifically to those accused of direct participation in the attack, not to the wider detainee population.

No defendants have been prosecuted through Israel's civilian courts for October 7-related crimes. Military legal officials had argued the cases should remain within the civilian justice system, but lawmakers overrode that position [5].

Structure and Procedural Framework

The tribunal will operate as a special court within the military justice system, seated in a dedicated judicial compound in Jerusalem [1][4]. Its bench consists of 15 judges who are either qualified to serve on Israel's Supreme Court or are international jurists approved by the justice minister in consultation with the foreign minister [1].

Individual cases will be heard by three-judge panels, each headed by a sitting or retired district court judge, while cases involving multiple defendants will go before five-judge panels [1][5]. Appeals from the tribunal go to the full 15-judge court, rather than to Israel's regular appellate system — a departure from standard procedure that critics have flagged [7][5].

Proceedings will be open to the public, recorded on audio and video, and broadcast on a dedicated website [1][4]. Key hearings — opening arguments, verdicts, and sentencing — will be livestreamed. Victims and survivors will be permitted to attend in person, and dedicated provisions govern victim participation [4]. Defendants will attend major hearings in person but may appear by video conference for others [3].

The law provides for legal representation, though the specific arrangements differ from civilian court standards. Adalah, an Israeli legal center for Arab minority rights, has argued that "the bill denies suspects the basic procedural protections essential to a fair trial" [8]. Of particular concern: the legislation permits judges to depart from standard evidentiary procedures and grants "broad judicial discretion to admit evidence obtained under coercive conditions that may amount to torture or ill-treatment," according to Adalah's legal analysis [9][8].

The Death Penalty Returns

The tribunal law's most dramatic provision is its authorization of capital punishment. Israel has carried out only two executions in its history — the last being the hanging of Nazi war criminal Adolf Eichmann in 1962 [4][3]. The new law grants the tribunal "full authority to impose the death penalty," in the words of Justice Minister Yariv Levin [4].

A separate law passed on March 30, 2026 already requires hanging for some Palestinians convicted of deadly attacks in military courts, but that measure does not apply retroactively to the October 7 defendants [5][7]. The tribunal law fills that gap, enabling capital sentences specifically for those prosecuted under its framework.

Death sentences require a majority vote of the judicial panel and trigger an automatic appeal regardless of the defendant's wishes [3][7]. Implementation procedures are left to future regulations [4].

MK Yulia Malinovsky, who co-authored the bill alongside coalition member Simcha Rothman of the Religious Zionism Party, compared the planned proceedings to the 1961 Eichmann trial, which "broadcast live and recorded testimonies of Holocaust survivors" [4][7]. She argued the law would prevent defendants from "dying of old age before trial" [3].

The Prisoner Exchange Lock

One of the law's most consequential provisions bars anyone indicted or convicted under the tribunal from being released in future prisoner exchanges or diplomatic agreements [5][7]. This eliminates a negotiating tool that has defined Israeli-Palestinian conflict dynamics for decades.

In the 2011 Gilad Shalit deal, Israel released 1,027 Palestinian prisoners — including senior Hamas leaders — in exchange for a single captured soldier [10]. In the ceasefire exchanges following October 7, Israel traded approximately 2,000 Palestinian detainees and prisoners, including 250 serving life sentences for terrorism, in exchange for 24 Israeli hostages [11].

The prisoner swap restriction creates a two-track system: defendants prosecuted under the tribunal cannot be bargained away, while those held under other legal frameworks potentially can. For hostage families, this raises a difficult question. Representatives of hostage families had previously called for a comprehensive "all for all" exchange [10]. The tribunal law narrows that possibility by removing a category of prisoners from the negotiating table.

Rights organizations including Hamoked, Adalah, and the Public Committee Against Torture in Israel have acknowledged that "justice for the victims of October 7 is a legitimate and urgent imperative" but insist accountability "must be pursued through a process which includes rather than abandons the principles of justice" [9].

How It Compares: Military Courts Past and Present

Israel's existing military court system in the occupied West Bank provides a reference point. Established in 1967 after the Six-Day War, those courts have processed hundreds of thousands of Palestinian defendants over nearly six decades [12][13]. Their conviction rate stands at 99.74%, with the vast majority of convictions resulting from plea bargains — a figure that critics attribute to the denial of bail in most cases, making guilty pleas the fastest path to release [12][13].

The new tribunal differs from the West Bank military courts in several respects: it will be staffed by civilian-caliber judges rather than uniformed soldiers, proceedings will be public and broadcast, and it handles a specific category of cases rather than the full range of security offenses. Supporters argue these features represent a higher standard of due process than the existing system [1][4].

The comparison to the U.S. military commissions at Guantánamo Bay is instructive but imperfect. Both systems were created to prosecute foreign fighters accused of terrorism, and both have drawn criticism for lacking the procedural safeguards of civilian courts [14][15]. At Guantánamo, proceedings have been plagued by years-long delays — the trial of the five men accused of planning the September 11 attacks did not produce plea agreements until mid-2024, more than two decades after the attacks [14]. The Israeli tribunal's supporters argue that their system's design avoids some of Guantánamo's problems: public proceedings, civilian judges, and a defined defendant pool.

Ya'ara Mordecai, an international law expert at Yale Law School, acknowledged the tribunal's structural improvements over standard military courts but flagged "some concerns about due process, given the military court setting," as well as a risk of proceedings "turning into politicized or symbolic show trials" [2][8].

Constitutional and Legal Challenges

Israel lacks a formal constitution but operates under a series of quasi-constitutional Basic Laws. The Supreme Court (sitting as the High Court of Justice) demonstrated its willingness to strike down legislation in January 2024, when it nullified the government's "reasonableness" amendment in an 8-7 decision — the first time the court had ever annulled a Basic Law provision [16].

In that ruling, 12 of 15 justices agreed the court holds authority to review Basic Laws and intervene in "exceptional, extreme cases" where the Knesset deviates from Israel's core identity as a Jewish and democratic state [16]. Whether the tribunal law crosses that threshold is an open question. No Supreme Court challenge to the tribunal law has been publicly announced as of May 2026, though human rights organizations have signaled their intent to contest it.

The 93-0 vote complicates any judicial challenge. The court typically shows greater deference to legislation with broad parliamentary support, and striking down a unanimously passed law related to the October 7 attack would carry significant political risk.

International Law Exposure

The tribunal raises questions under international humanitarian law (IHL) and the Geneva Conventions. As a High Contracting Party to the 1949 Geneva Conventions, Israel is bound by their provisions regarding the treatment of captured combatants and the conduct of military proceedings [17].

The Fourth Geneva Convention requires that protected persons be tried by "a regularly constituted court" providing "the judicial guarantees which are recognized as indispensable by civilized peoples." Whether the new tribunal meets that standard — particularly given concerns about coerced evidence and deviations from normal evidentiary rules — will be the subject of international legal scrutiny [17][8].

Israel faces existing proceedings at both the International Criminal Court and the International Court of Justice. The ICC issued arrest warrants for Netanyahu and former Defense Minister Yoav Gallant in November 2024 on charges of war crimes and crimes against humanity [17][18]. The ICJ is separately hearing a genocide case brought by South Africa. While Israel does not recognize the ICC's jurisdiction (it signed but never ratified the Rome Statute), the ICC maintains jurisdiction over crimes committed in Palestinian territory and by Palestinian nationals on Israeli territory [17].

If the tribunal's proceedings are found to lack basic fair trial guarantees, this could strengthen the ICC's hand. Under the Rome Statute's complementarity principle, the ICC can take jurisdiction when national proceedings are deemed unwilling or unable to genuinely carry out prosecutions. A tribunal that admits coerced evidence or operates without adequate defense rights could be characterized as a "sham proceeding" that fails the complementarity test, opening further legal exposure for Israel [17][18].

The Case For and Against

Supporters frame the tribunal as an unprecedented accountability mechanism. The October 7 attack killed at least 1,139 people, mostly civilians, and resulted in the seizure of approximately 240 hostages [2][9]. No legal proceeding of comparable scope has been attempted in Israeli history. Supporters argue that military tribunals offer faster proceedings, operational security for classified intelligence, and judges with relevant expertise — advantages that outweigh the procedural trade-offs [4][3].

The Eichmann trial analogy resonates with the Israeli public: a public, broadcast proceeding that documented atrocities for the historical record while delivering a verdict. Justice Minister Levin called the law's passage "one of the most important moments" in Israel's pursuit of justice for the attack [4].

Critics raise several objections. Adalah argues the framework is "fundamentally incompatible with the right to life, the presumption of innocence, judicial independence and the rule of law" and that any death sentence imposed would constitute "an arbitrary deprivation of life, absolutely prohibited under international law and potentially a war crime" [8][9]. Amnesty International and Human Rights Watch have described the legislation as institutionalizing inequality based on ethnicity [9].

The Palestinian Authority has denounced the law as racist and discriminatory [2]. Hamas spokesperson Hazem Qassem characterized it as a cover for Israeli war crimes in Gaza [3][9].

Military legal officials within Israel's own system had warned against moving the cases out of civilian courts, arguing that the civilian system's procedural protections would produce more durable convictions less vulnerable to international legal challenge [5].

Timeline and Implementation

Implementation faces significant hurdles. The Defense Ministry estimates the initiative will cost approximately NIS 5 billion ($1.72 billion), primarily for a dedicated judicial compound and a staff of roughly 400 soldiers and civilian employees [1]. Disagreements between the defense and finance ministries over funding could delay the tribunal's establishment [1].

Once operational, regular proceedings could take four to five years, according to Israeli legal reporting [5]. The first indictments could come months after the tribunal is formally established, depending on how quickly the judicial compound is built, judges are appointed, and translators and defense attorneys are arranged.

For comparison, major terrorism prosecutions in Israel's civilian courts have historically taken years. The perpetrators of terrorism cases involving multiple defendants and complex evidence have routinely consumed the better part of a decade when accounting for investigation, trial, and appeals. The Guantánamo military commissions took more than 20 years to reach plea agreements in the September 11 case [14].

The tribunal's proponents argue its focused mandate — a defined set of defendants, a single attack, abundant forensic evidence — should produce faster results than either Israel's civilian courts or the Guantánamo precedent. Whether that projection holds will depend on factors including the scale of individual trials, the number of defendants who contest the charges, and the resolution of the funding dispute between ministries.

What Comes Next

The law is now on the books, but the tribunal does not yet exist as a physical or operational institution. The sequence ahead involves budgetary negotiations, facility construction, judicial appointments, and the preparation of individual indictments from what prosecutors describe as extensive forensic and documentary evidence [5][4].

The legal challenges — domestic and international — are likely to begin before the first gavel falls. Human rights organizations have the tools and precedent to petition the Israeli Supreme Court. The ICC investigation continues separately. And the prisoner exchange restriction will test whether the law's architects have correctly assessed that accountability outweighs the diplomatic flexibility Israel has historically relied on to recover its own citizens from captivity.
