On March 29, 2023, in a historic move, the United Nations General Assembly adopted Resolution A/77/L.58 by consensus, requesting the International Court of Justice (ICJ) to issue an advisory opinion on the obligations of States concerning climate change and human rights.
The Philippines actively participated in the proceedings through the submission of a Written Statement and its involvement in the Oral Arguments.

Launch of the Monograph on the Roundtable Discussion on Examining the Rules-Based International Order (RBIO) from Perspectives in International Law
The term “rules-based international order” (RBIO) has been the subject of debate among scholars.

Following this roundtable discussion, IILS and DFA are now officially launching the monograph of the discussion.
