Well, no, not exactly. Obama and others have urged Texas to abide by the treaty between the US and Mexico giving accused criminals in either nation the right to contact their respective consuls when arrested. This was not done in this case - or in a number of others in the US. The Federal government of the US has no power to compel a state to comply with directives of the ICJ, whether it wanted to or not. BTW, I assume that you realize that the ICJ and the ICC are separate entities, since your post juxtaposes the two a bit.
