59 Based on research on file with the author.

60 It was challenging to find any comprehensive information of court judgements from Mali and Afghanistan, other than in the US country report. NGO reports also make reference to efforts by the courts but do not provide any specific statistics that would be worth including. Hence, these numbers are not complete.

61 Based on US Country Reports on Terrorism. For 2016, see https://www.state.gov/wp-content/uploads/2019/04/crt_2016.pdf, pp. 39–41, for 2017, see https://www.state.gov/wp-content/uploads/2019/04/crt_2017.pdf, p. 29; for 2018, see https://www.state.gov/wp-content/uploads/2019/11/Country-Reports-on-Terrorism-2018-FINAL.pdf, p. 30; for 2019, see https://www.state.gov/wp-content/uploads/2020/06/Country-Reports-on-Terrorism-2019-2.pdf. The 2016 (p. 238) and 2017 (p. 169) reports note that the Attorney-General's office prosecutes a number of terrorist offences and highlights six particular cases in total; the subsequent reports do not mention specific cases, but imply there are numerous cases (2019 report, p. 152).

62 On the basis of field experience of the author in Afghanistan specifically working on criminal processes.

63 For Australia and The Netherlands (the two countries for which there were the most accurate court reports) the prosecutions were for conduct related to an armed conflict situation, i.e. as an alleged member of a “terrorist” organization in territory where an armed conflict was taking place. Other prosecutions not included are prosecutions such as financing of terrorism, conspiracy to commit domestic terror attacks or actual participation in a domestic terrorist attack.

64 Cases from October 2017 to 2020, available at: https://csd.njca.com.au/recent-cases/#PID_8118; cases from 2015 to 2017 from search of all Australian case law, available at: http://www.austlii.edu.au/advanced_search.shtml.

66 Based on US Country Reports on Terrorism, 2016, 2017, 2018 and 2019, above note 61. In 2017, it was reported that “[i]n 2017, the government opened 69 terrorism-related cases and detained 30 people for terrorism-related crimes. Resource constraints, a lack of training in investigative techniques, and inexperience with trying terrorism cases plagued a weak judicial system. The Malian government has never investigated, prosecuted, and sentenced any terrorists from start to finish.” (p. 29)

67 On the basis that all the other instances covered are 0 and that the ICC is investigating Mali, and no domestic cases have been reported in that context which is otherwise public.
