I presented my research to the North South Webinar Series, based on my previous Research Handbook on International Law and Peace (Edward Elgar 2019) and my forthcoming Research Handbook on International Law and Solidarity (Edward Elgar 2023). I will discuss the normative evolution of these third generation rights, the link to the UN Report Our Common Agenda, solidarity paradoxes in an age of decoupling and recoupling, as well as securitized peace and solidarity. There is a role for peace and solidarity in the context of transitional justice, and hence relevant to intractable conflicts like Palestine in which peace and solidarity civic society spaces are under threat. I argue for a pro homine peace and solidarity that is gendered, intergenerational, and inclusive. Peace and Solidarity are both means and ends as they call for pacific settlement of disputes, recognition of the right to freedom of expression (including digital access) and equitable participation and benefit in the common heritage of mankind.
