ICJ: International Court of Justice set to hear Guyana v Venezuela

The International Court of Justice (“ICJ”) is set to hold public hearings this week (4 May onwards) in the matter of Guyana v Venezuela. It concerns an arbitral award from 3 October 1899 in which an international tribunal in Paris awarded the majority of the Essequibo region to British Guiana (now Guyana).

Venezuela claims that there was a flaw in the award and the dispute should be resolved through the 1966 Geneva Agreement process. While Guyana filed an application to begin proceedings in the ICJ back in 2018, Venezuela refused to participate on the basis that the Court lacked jurisdiction to hear the case. However, a judgment from 2020 found that the ICJ could entertain the application for the purposes of definitive settlement.

The ongoing dispute caused a stir only a few days ago, when it was reported that the acting President of Venezuela, Delcy Rodriguez, work a brooch depicting a map of Venezuela including the Essequibo region, claimed by both countries.

Blog Corner: “Caught in the Legal Crossfire? Critical Minerals Agreements and International Economic Law”

In a post on EJIL: Talk! Jesse Coleman and Lorenzo Cotula examine the emergence of bilateral ‘critical mineral agreements’ which they say, may cause a departure with established international economic law obligations. Such agreements may take different forms, including memoranda of understanding, framework or strategic partnerships or mineral-specific obligations into trade and investment agreements. The use of soft-law instruments may further be seen as part of a wider policy concern about what they describe as “rapidity of public action” but also as a means of bypassing constitutional safeguards.
