Sovereign Shield: Saudi Arabia’s Endlessly Delayed Day in Court

Quarter of a century after four hijacked airliners reshaped global politics and claimed nearly 3,000 lives, the American judicial system is still tangled in the foundational question of whether a foreign state can be held financially and legally accountable in a domestic courtroom. In New York, the Court of Appeals recently took under advisement a high-stakes challenge by Saudi Arabia, which is desperate to halt a civil lawsuit filed by the families of 9/11 victims before it reaches a full trial.

The central friction rests on the concept of foreign sovereign immunity—a principle states routinely invoke to shield themselves from domestic litigators abroad. For the plaintiffs, who first launched their legal battle in 2002, breaking through this legal armor required years of intense political lobbying. Their efforts culminated in 2016 when Congress enacted the Justice Against Sponsors of Terrorism Act, specifically carving out exceptions to sovereign immunity for foreign states in cases involving acts of international terrorism on American soil. Armed with this statute, the families secured a pivotal victory in August 2025, when the Manhattan District Court ruled that sufficient evidence existed regarding Saudi state involvement to advance toward trial.

Now, Saudi Arabia is demanding a total reversal of that decision. Defense counsel Gregory Rapawy insisted before the appeals panel that core factual questions remain unresolved, particularly concerning the exact nature of employment for Omar al-Bayoumi. Bayoumi, a now-retired Saudi government employee linked to the Ministry of Islamic Affairs, is accused of providing knowing support to two of the 9/11 hijackers. While Riyadh maintains that any claim of state complicity is categorically false and Bayoumi denies knowing the hijackers, the plaintiffs' legal team argues the factual record is already clear. Attorney Gavin Simpson stressed that the lower court had already determined Bayoumi acted under explicit instructions from the Kingdom rather than as an innocent bystander.

The appellate panel, led by Judges William Nardini and Guido Calabresi, now faces a delicate procedural choice. Beyond simply affirming or overturning the lower court, the judges hinted at sending the case back down for further factual determinations—a move that could require live witness testimony, potentially even calling Bayoumi himself. Such a procedural detour would once again postpone any trial. For victims' relatives like Terry Strada, who lost her husband in the World Trade Center, the prospect of further delay underlines the sheer friction of seeking legal recourse against a sovereign nation. Whether the American court system will ultimately pierce Riyadh's legal shield remains a question deferred to a future ruling.
