Nacionalidad, derecho internacional y la Constitución de 1833

This article examines the constitutional rules governing nationality and their interpretation in accordance with doctrines of international law, using a historical case study. The analysis is illustrated with two contradictory judgments on the legal nature, nationality, and its regulation in the Constitution of 1833. Both rulings decide on children of foreigners and military service. The intensity with which our legal system accepts the law of nations is fundamental in both judgments. A case related to children of Peruvians born in territory occupied by the Chilean army after the Pacific War is also analyzed. Aspects of contemporary international law on nationality and comparative elements are mentioned.
