Please find a modest note on formal protest issued this week by Costa Rica against an official publication made by Nicaragua related to oil concessions areas in the sea.

(In Spanish and in English)

Possible new case coming soon at ICJ between the same two.

There is no delimitation treaty of marine areas between Costa Rica and Nicaragua. A very singular case in the region.
