This “spatial” conceptualization is used to explain the inapplicability of immunity ratione personae before courts and tribunals of an “international” character, in contrast with those of a “domestic” character. See, e.g., Bashir (2019), Joint Conc. Op. of Judges Eboe-Osuji, Morrison, Hofmański and Bossa, ¶ 430 (referring to the “bilateral (or horizontal) obligation of inviolability of the immunity of Mr. Al-Bashir (as Sudan's Head of State).”).

29 Thomas Weatherall, Prosecutor v. Omar Al-Bashir (Int'l Crim. Ct.), 58 I.L.M. 1177, 1178 (2019). See Thomas Weatherall, Inviolability Not Immunity, 17 J. Int'l Crim. Just. 45 (2019). See contra Bashir (2019) ¶ 97 (“The central issue in this appeal is whether Mr. Bashir, in his capacity as Head of State of Sudan, enjoyed immunity before this Court which Jordan was obligated to respect in the absence of a waiver from Sudan.”).
30 Bashir (2019), ¶¶ 122, 143.
31 See id. ¶¶ 123, 141, 144 (discussed infra).
32 See contra id. ¶ 145 (“there were also no ‘irreconcilable legal obligations’ that Jordan was facing when being asked to arrest and surrender Mr. Al-Bashir to the Court.” (citation omitted)). Under Rome Statute Article 86, states parties are subject to a “general obligation to cooperate” with the court, i.e., to “cooperate fully with the Court in its investigation and prosecution of crimes within the jurisdiction of the Court.” Such cooperation includes compliance with requests for arrest and surrender pursuant to Article 89. Relatedly, Article 59 provides that “[a] State Party which has received a request for provisional arrest or arrest and surrender shall immediately take steps to arrest the person.”
33 U.N.S.C. Res. 1593, U.N. Doc. S/Res/1593 (Mar. 31, 2005). All states, as well as concerned regional and other international organizations, were “urge[d]” to cooperate fully with the ICC.

36 Putin (2024), ¶ 40. Though the Chamber did not use the Latin term of art, obligations erga omnes are defined in these terms: see, e.g., Barcelona Traction, Light and Power Company, Limited (Belgium v. Spain), Judgment, I.C.J. Rep. 1970, p. 3, ¶ 33.

41 PTC II referred to the obligation to cooperate in the arrest and surrender of Putin as both an obligation towards the international community as a whole (erga omnes) as well as an obligation towards other states parties (erga omnes parties). Compare Putin (2024), ¶ 40, with id. ¶ 33. The latter would be the more natural characterization of a treaty-based obligation giving rise to a general legal interest in its performance. It is unclear whether the Chamber intended to suggest that there exists an obligation erga omnes of cooperation under CIL, parallel to Rome Statute Article 86, that is owed to the international community as a whole.
