New York Court Hears Arguments in 9/11 Lawsuit Against Saudi Arabia

The Court of Appeals in New York recently heard critical legal arguments from both lawyers representing families of 9/11 victims and representatives of the government of Saudi Arabia. This session is part of a decades-long effort by the plaintiffs to bring their lawsuit to a full trial. Almost 3,000 people lost their lives on September 11, 2001, when commercial airliners were hijacked and crashed into the World Trade Center, the Pentagon, and a field in Pennsylvania. Ever since, grieving families have sought accountability, pursuing various legal avenues to uncover the full extent of the conspiracy and any potential institutional backing.

At the center of the current appeal is the allegation that a former Saudi government employee, Omar al-Bayoumi, knowingly supported two of the hijackers who carried out the attacks. The families claim that Bayoumi was working alongside a network of officials linked to the Saudi Ministry of Islamic Affairs. Bayoumi, who has since retired from government work, has consistently denied knowing that the two men were hijackers and maintains he had no involvement in the tragedy. The Saudi government has also categorically rejected any claims of complicity, asserting that it bears no responsibility for the actions of individuals and is protected by foreign sovereign immunity.

The legal pathway to this hearing has been extraordinarily complex. The families first filed their lawsuit in 2002, but faced major hurdles due to the traditional protections afforded to foreign states in US courts. To overcome this, the plaintiffs spent years lobbying the United States Congress to amend the law. Their efforts culminated in 2016 when Congress passed the Justice Against Sponsors of Terrorism Act, commonly known as JASTA. This legislation created an exception allowing civil claims against foreign states or officials for injuries, deaths, or damages stemming from acts of international terrorism.

In August 2025, the Manhattan District Court ruled that the families had gathered enough evidence to meet the legal requirements of JASTA, allowing the case to move forward toward a trial. Seeking to overturn that ruling, Saudi Arabia's legal counsel, Gregory Rapawy, argued before the Court of Appeals that core issues of fact—such as the exact nature of Bayoumi's employment status with the state—remain unresolved and must be addressed before the nation can be stripped of its sovereign immunity. On the other side, the families' lawyer, Gavin Simpson, argued that the lower court had already established that Bayoumi's assistance to the hijackers went far beyond innocent behavior, acting instead on instructions from the state.

During the proceedings, the panel of judges appeared to deliberate on whether to remand the case back to the district court for more concrete factual findings, which could potentially require testimony from live witnesses. When questioned about potential witnesses, Rapawy noted that if witness credibility becomes central, the defense would evaluate whether Bayoumi himself could be called to testify. As the hearing concluded, Judge William Nardini acknowledged the complexity of the matter, stating that the court would take the case under advisement and issue a decision at a later date. This pivotal moment marks another chapter in a relentless pursuit of justice that has spanned more than two decades.
