In the paper we consider the conical parallel of latitude circles.
As comparing Euclidean example we presented the diameter of the conical parallel of latitude which does not pass through its centre.
In the case of 20 of the 53 arrests, the report records or indicates the place at which the arrests took place and all of those places are far to the north of the parallel of latitude extending from the land boundary between Peru and Chile, and closer to the boundary between Peru and Ecuador.
In respect of these incidents, the Court recalls that the zone of tolerance established under the 1954 Agreement starts at a distance of 12 nautical miles from the coast along the parallel of latitude.
For its part, Peru stresses that neither its Note of January 1976 nor its alternative proposal of November 1976 mentioned a parallel of latitude or suggested any method of maritime delimitation for Bolivia's prospective maritime zone.
1 as the reference point for the parallel of latitude constituting the maritime boundary between the Parties", further contending that the Parties have also used the parallel passing through this point as the maritime boundary for the capture and prosecution of foreign vessels.
As the Court has already noted (see paragraph 183 above), the existence of an agreed line running for 80 nautical miles along the parallel of latitude presents it with an unusual situation.
The Court concludes that the maritime boundary between the Parties starts at the intersection of the parallel of latitude passing through Boundary Marker No.
Decides that the starting-point of the single maritime boundary delimiting the respective maritime areas between the Republic of Peru and the Republic of Chile is the intersection of the parallel of latitude passing through Boundary Marker No.
For the reasons set out in this opinion, I do not concur with the view of the majority of the Court that an agreed all-purpose maritime boundary already exists between the Parties along the parallel of latitude passing through the Boundary Marker No.
Acknowledging that the Santiago Declaration contains no clear and unequivocal delimitation provision, Chile asserts that Article IV thereof should be interpreted as establishing an international maritime boundary between Chile and Peru along the parallel of latitude passing through the starting-point of their land boundary and extending to a minimum of 200 nautical miles seaward.
Nevertheless, the Court holds that it is precisely on the basis of "a tacit agreement" that an all-purpose maritime boundary already exists between the Parties along the parallel of latitude passing through the Boundary Marker No.
