¹⁹ In Trial of Captain Eikichi Kato ((n 13) 38) Captain Kato was found guilty of the murder of civilians; the victims were not granted the right to a fair trial before being shot as ‘[a] mere discussion between officers as to the merits of a case, based upon reports of interrogations, would not in fact constitute a trial’. In Trial of Karl Adam Golkel and Thirteen Others ((n 13) 51) the defendants were convicted of the killing of prisoners of war without any legal justification or trial; the defence did not even claim that a trial of the victims was held.

⁵⁶ This is one of the possible meanings that the Merriam-Webster Dictionary gives to the adjective: Merriam-Webster, ‘judicial’, https://www.merriam-webster.com/dictionary/judicial?src=search-dict-box. The same definition is endorsed by the Oxford Dictionary: ‘of, by, or appropriate to a law court or judge; relating to the administration of justice’: ‘judicial, adj. and n.’, OED Online, September 2020, https://www.oed.com/view/Entry/101916?redirectedFrom=judicial.

⁵⁷ What is intended here with ‘trial’ is that part of the criminal proceedings consisting of hearings where issues of fact and law are disputed by the parties in front of the deciding authority to assess the guilt of the accused.

⁹⁶ According to GC IV (n 29) art 5, regulating derogations, also persons detained in occupied territories as spies, saboteurs or otherwise suspected of conducting activities that are hostile to the security of the Occupying Power ‘shall not be deprived of the rights of fair and regular trial’. On AP I, art 75, see Commentary Additional Protocols (1987) (n 72) para 3092: ‘Article 75 is not subject to any possibility of derogation or suspension and consequently it is these provisions which will play a decisive role in the case of armed conflict’.

¹⁴¹ This is what is provided by the ICC Statute (n 36) art 28(a). On the issue see, eg, Commentary GC III (2020) (n 64) art 3, para 726 (referring to ICC, Prosecutor v Bemba, Decision pursuant to Article 61(7)(a) and (b) of the Rome Statute on the Charges of the Prosecutor against Jean-Pierre Bemba Gombo, ICC-01/05-01/08-424, Pre-Trial Chamber, 15 June 2009, para 501, and ICC, Prosecutor v Bemba, Judgment pursuant to Article 74 of the Statute, ICC-01/05-01/08-3343, Trial Chamber, 21 March 2016 (Bemba Trial Judgment), paras 205–09). See also Stockholm District Court, Prosecutor v Haisam Omar Sakhanh, Judgment, Case B 3787-16, 16 February 2017, paras 29 and 31, in ‘On the Establishment of Courts in Non-International Armed Conflict by Non-State Actors: Stockholm District Court Judgment of 16 February 2017’ (2018) 16 Journal of International Criminal Justice 403 (which states that non-state actors ‘can establish tribunals to (1) maintain discipline among the group's own armed units and (2) to maintain law and order in a given territory which the group controls’). The argument is also recalled in Al Hassan, Defence Submissions for the Confirmation of Charges (n 139) para 254.

¹⁴² For further details on the issue see, eg, Sivakumaran (n 129) 498, 510ff. Also, the solutions suggested by Amnesty International (in ICC, Prosecutor v Bemba, Amicus Curiae Observations on Superior Responsibility submitted pursuant to Rule 103 of the Rules of Procedure and Evidence, ICC-01-/05-01/08, Pre-Trial Chamber, 20 April 2009, para 20) to refer the case to the authorities of other states or to international authorities are deemed ‘unpracticable’ by part of the scholarship: see Spadaro (n 140).

¹⁵¹ At times the requirement is considered equivalent to ‘competent’, meaning that ‘the tribunal has been established by law to decide cases relating to certain subject matters’: Louise Doswald-Beck, ‘Judicial Guarantees under Common Article 3’ in Clapham, Gaeta and Sassòli (n 71) 469, 470.

¹⁵² Sivakumaran (n 129) 499–500; Commentary GC II (2017) (n 127) para 714; Somer (n 137) 687–90. This line of interpretation is supported in Al Hassan, Defence Submissions for the Confirmation of Charges (n 139) para 254.

There is no legal basis to argue that when ANSAs exercise factual power they are forbidden to change the existing legal order.
