Hello,

The statements made by the government of Peru about its maritime domain obviously apply to the entire maritime domain, not just near Chile. The meaning of the maritime domain is also clearly relevant to that court case, because without the claim of a maritime domain there would be no dispute in the first place. The statement is also not just some interpretation but the court has noted it as an explicit commitment.

If you look at the exact contents of the statement, Peru says the maritime domain is applied consistently with UNCLOS. This means a 200 nm territorial sea is not the current situation on the ground, regardless of what the constitution says Peru is entitled to.

Maybe a different government in the future will successfully claim a territorial sea of 200 nm, based on the constitution, but until that happens the maritime borders should be mapped as they are effectively applied today.
