Assuming no dramas like in 2017, one can expect 'clean slates' for Js Xue and Iwasawa, and for Pr Nolte.
Pr Nolte's #ICJ candidacy was announced back in late 2018: https://www.auswaertiges-amt.de/en/aussenpolitik/themen/internatrecht/goerg-nolte-icj-2021-30/274690
Japan announced J Iwasawa's (expected) candidacy a few months later: https://www.mofa.go.jp/press/release/press4e_002346.html https://twitter.com/bknussberger/status/1283275311036215296

Currently on paper is a three-way contest for one of the African Group 'seats'. However, there are reports that states are negotiating withdrawals, which could partly hinge on #AU's candidate for #WTO DG: https://www.africaintelligence.com/central-and-west-africa_diplomacy/2020/07/08/au-abuja-kigali-kampala-vie-to-fill-african-seat-on-icj-bench,109242960-ar1
However, rivalry and tense relations between Rwanda and Uganda may prevent the possibility of a clean slate for that seat. https://mulengeranews.com/m7-kagame-in-new-war-over-sebutinde-icj-job/
As for for Eastern European Group 'seat', re-upping this thread from June. #ICJ_elections https://twitter.com/OriPomson/status/1273943068597764097?s=20
