US sanctions
On 20 August 2025, the US Treasury's Office of Foreign Assets Control imposed sanctions on Guillou as a member of the pre-trial panel that approved and issued arrest warrants against Israeli Prime Minister Netanyahu and former defense minister Gallant. Guillou’s name was listed among 15,000 people, including Al-Qaeda terrorists, drug cartel members, and Vladimir Putin. The effect of the sanctions means that Guillou is banned from US territory. Under US law, the sanctions also prohibit any American individual or legal entity, as well as any person or company, including their overseas subsidiaries, from providing services to him. This has had the effect of blacklisting him from the world's banking system. As a result of the sanctions, Gillou and his family were barred from using most credit cards, including Mastercard and VISA, and using online travel booking or deliveries that involve an American intermediary.

Why this record matters
The subject matters to the general reference register because the source frames it as french judge on the International Criminal Court since 2024. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q125985448. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1975, 2006, 2009 and 2012.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
