Solicitor General Urges SCOTUS Deny KSM Plea Reinstatement

• U.S. Solicitor General D. John Sauer has urged the Supreme Court to reject a bid by Khalid Sheikh Mohammed and a co-defendant to restore plea agreements that would spare them the death penalty.
• The defendants are seeking review of a federal appeals court ruling that allowed the Pentagon to withdraw from these agreements.
• A Pentagon official initially approved the agreements on July 31, 2024, but then-Defense Secretary Lloyd Austin canceled them two days later.
• A military judge and a military appeals court initially ruled that Austin's cancellation was too late, as defendants had begun fulfilling obligations.
• The D.C. Circuit reversed these decisions in July 2025, blocking the military judge from accepting the pleas and upholding the Pentagon's withdrawal.

The Solicitor General's stance directly opposes the defendants' petition, which aims to overturn a ruling by the D.C. Circuit that effectively blocked a military judge from accepting their guilty pleas and upheld the Pentagon's decision to retract the agreements.

The U.S. Solicitor General, D. John Sauer, has formally requested the Supreme Court to reject efforts by Khalid Sheikh Mohammed, the alleged mastermind of the September 11 attacks, and a co-defendant to reinstate plea agreements that would remove the possibility of the death penalty. This significant development comes as the alleged attackers seek Supreme Court review of a federal appeals court decision that permitted the Pentagon to withdraw from these crucial agreements.

These filings represent a critical juncture in the long-running legal saga surrounding the 9/11 defendants. The Solicitor General's stance directly opposes the defendants' petition, which aims to overturn a ruling by the D.C. Circuit that effectively blocked a military judge from accepting their guilty pleas and upheld the Pentagon's decision to retract the agreements. The Supreme Court's decision on whether to hear the case, referred to as US v Khalid Sheikh Mohammed SCOTUS, will have profound implications for the future of military commission proceedings.

The plea agreements in question were initially approved by a Pentagon official under the Biden administration on July 31, 2024. However, just two days later, then-Defense Secretary Lloyd Austin canceled them, asserting that a decision of such magnitude required his direct approval. This swift reversal set off a chain of legal challenges.

A military judge subsequently ruled that Secretary Austin's cancellation came too late, as the defendants had already begun fulfilling their obligations under the terms of the plea agreements. This ruling was then upheld by a military appeals court, suggesting that the agreements were indeed binding. However, the legal landscape shifted dramatically in July 2025 when the D.C. Circuit reversed these prior decisions, thereby blocking the military judge from accepting the guilty pleas and validating the Pentagon's withdrawal from the agreements.

The D.C. Circuit's ruling, which allowed the Pentagon's withdrawal to stand, is now the central point of contention before the Supreme Court. The Solicitor General's urging for the Court to deny the 9/11 plea agreement review underscores the executive branch's desire to maintain the option of capital punishment for Khalid Sheikh Mohammed and his co-defendant, despite the prior agreements. This legal battle highlights the complex interplay between executive authority, military justice, and the rights of defendants in high-stakes national security cases.

Should the Supreme Court decline to hear the case, the D.C. Circuit's decision would stand, effectively nullifying the Khalid Sheikh Mohammed 9/11 plea agreement and potentially paving the way for death penalty military tribunals. Conversely, if the Court grants review, its eventual ruling could set a significant precedent regarding the enforceability of plea agreements within military commissions and the extent of executive power to unilaterally withdraw from such arrangements, particularly in capital cases.

This development signals a critical juncture in the long-running legal saga of 9/11 detainees, particularly regarding the enforceability of plea agreements in military commissions. Lawyers advising on national security, military justice, or capital defense should closely watch SCOTUS's decision, as it could set significant precedent on executive authority to unilaterally withdraw from such agreements and impact the future of military commission proceedings.
