2021 Statelessness & Citizenship Review 3(1) subjected violated these rights, which are provided for in arts 77 and 66 of the Constitution of Ecuador. 39 Finally, the Court ruled that the arbitrary detention of the plaintiff disregarded his right to migrate, considering that ‘detentions of persons based on their migratory status, regardless of the place of detention, whether in airports, transit zones or ‟international” zones, are practices that promote the criminalisation of migration’, 40 under art 40 of the Constitution of Ecuador, art 16 of the CRMW 41 and art 7 of the ACHR. 42 REASONING The ruling handed down by the Constitutional Court of Ecuador in JP has no precedent in the Ecuadorian legal system. It also has no precedent in the domestic legal systems of the region in terms of the right to nationality, statelessness, limits of the discretionary power of the state in cases of revocation of nationality by naturalisation and minimum guarantees of due process to avoid arbitrary deprivation of nationality. In addition, the Constitutional Court established clear guidelines on the following issues: (a) Characteristics of the notification of decisions in proceedings for revocation of nationality or with revocation effects. 43 (b) Limits to the detention of migrants in transit or in international zones at airports, in accordance with the duration of detention, as a guarantee to avoid arbitrariness. 44 (c) Adequacy of the mechanism of the action for protection for the defence of the constitutional rights of persons in a situation of human mobility. 45 Each of the parameters indicated by the Constitutional Court of Ecuador is based on the human rights norms and principles of the Inter-American system. The judgment supports, through jurisprudence, compliance with the standards of protection being binding on the countries of the region. It is clear from the characteristics of the judgment that it is binding as a constitutional precedent, with erga omnes effects established by the Court itself in future analogous cases. CONCLUSION Although the Constitutional Court of Ecuador has made other pronouncements related to the right to nationality in cases of birth registration of children of samesex couples, 46 or persons recognised as refugees, 47 the ruling discussed is a unique decision and without any precedent concerning the issues addressed. As such, it is likely to have an important impact on the Ecuadorian legal system for future judicial and regulatory developments.
