Ali Hamza Ahmad Suliman al-Bahlul (born September 11, 1969) is a Yemeni citizen who has been held as an enemy combatant since 2002 in the United States Guantanamo Bay detention camp.

He was convicted in November 2008 of performing media relations for Osama bin Laden, the founder of al-Qaeda, and sentenced to life imprisonment, after a jury of nine military officers deliberated for less than an hour.

[5] Joint Task Force Guantanamo counter-terrorism analysts describe Ali Hamza Ahmad Suliman al-Bahlul as al Qaeda's public relations director.

He set up a satellite receiver for Osama bin Laden, the leader of the terrorist organization, to listen to live radio coverage of the September 11, 2001 attacks in the United States.

[1] He faced charges before the first Guantanamo military commissions, before the United States Supreme Court ruled that they were unconstitutional under existing executive authority.

Lieutenant Commander Philip Sundel, his first military defense attorney, described the difficulty in getting a security clearance for a translator to talk to his client.

[19] Jane Sutton, reporting for Reuters, wrote that when Al-Bahlul's conviction was overturned it implied the highest profile trials, those against Khalid Sheikh Mohammed, and four other conspirators, also seemed more likely to face similar challenges.

The Circuit specifically directed the rehearing would consider the standard of appellate review and as to if Congress's attempts to define and punish war crimes transgresses the Article III powers of courts.

[26] Judges Patricia Millett and Robert L. Wilkins, voted to affirm Bahlul's conviction but did not join the plurality's opinion, each writing that the case should be decided on more narrow grounds.

"[26] One year later, the Supreme Court of the United States denied Bahlul's petition for a writ of certiorari without comment, with Justice Neil Gorsuch taking no part in considerations.
