Chaloka Beyani is a professor of international law at the London School of Economics and Political Science (LSE). He has worked and published extensively in the fields of international human rights law, international criminal law and international humanitarian law, as well as on issues relating to humanitarian assistance and population displacements, in particular internal displacement. In 2023 Beyani was nominated by Zambia for election to the International Court of Justice (ICJ). The Netherlands co-nominated Beyani. Zambia had previously put Beyani forth for the 2017 International Court of Justice judges election, but withdrew his name prior to the candidate selection process. If elected, he would have been the first Zambian judge at the ICJ. After five rounds of voting in the Security Council and one round of voting in the General Assembly, Beyani was not elected.
 Beyani is a recognized international and United Nations expert on internally displaced persons (IDPs), population transfers, the rights-based approach to development, climate change, sexual and reproductive health, mercenaries and private military companies, making treaties and making constitutions.
 His analysis and arguments on the protection of the human rights of IDPs have become highly influential in shaping state policies on the protection of IDPs, especially in Africa.
