Based on a novel data set of expatriate dual citizenship policies worldwide since 1960, we find that dual citizenship toleration has increased in the last half century from one-third to three-quarter of states globally. We argue that these domestic policy changes should be understood in light of normative pressure in a world where restrictions on individual choice in citizenship status are increasingly contested and where liberalisation is reinforced through interdependence and diaspora politics. We apply Cox proportional hazard models to examine dual citizenship liberalisation and find that states are more likely to move to a tolerant policy if neighbouring states have done so and that they tend to do so in conjunction with extending voting rights to citizens residing abroad and receiving remittances from abroad. Contrary to other studies, we do not observe significant variation by regime type.Publication Metadata only Het oude verbod van erkenning van kinderen door gehuwde Nederlandse mannen: een drama met vele afleveringen - Annotatie bij Hoge Raad 19 januari 2018, ECLI:NL:HR:2018:59 (antwoorden op prejudiciële vragen Gemeenschappelijk Hof)(Boom Juridisch Tijdschriften, 2018) de Groot, RenéIn de onderhavige annotatie staan de prejudiciële vragen in een Caribische zaak centraal die betrekking hebben op de verkrijging van het Nederlanderschap door erkenning in 1990 in het buitenland door een gehuwde man.Publication Metadata only MACIMIDE Global Expatriate Dual Citizenship Dataset(2015) Vink, Maarten Peter; de Groot, René; Luk, Ngo ChunThe MACIMIDE Global Expatriate Dual Citizenship Dataset charts the rules that existed in near all states of the world since 1960 with regard to the loss or renunciation of citizenship after a citizen of a respective state voluntarily acquires the citizenship of another state. The central variable of the Dataset is the dualcit_cat variable. This is a categorical variable whose values may be used to interpret, in broad lines, the position of a country with regards to the expatriate dual citizenship. The dualcit_cat variable reflects what consequences the legislation and legal practice of a country attaches to the voluntary acquisition of a foreign citizenship. The value of this variable depends on a number of criteria, including whether a citizen of the reference country who voluntarily obtains a foreign citizenship automatically loses – in principle – the citizenship of the origin country, and whether a citizen of the reference country can renounce that citizenship. The value assigned to dualcit_cat reflects the position of the country on the 1st of January of the reference year. Any subsequent changes in legislation will be reflected in the dualcit_cat value of the following year and included in updated versions of the Dataset. The dualcit_binary variable is a recoding of the dualcit_cat variable. This variable can be used for broad comparisons of the dual citizenship positions around the world. The possible values reflect whether the legislation of a country, in a given reference year, provides for the automatic loss of the origin citizenship (1) or not (2). All data have been centrally collected and refer to specific provisions in national law. The Extended Codebook refers to the relevant citizenship legislation as well as to the relevant article in the law and includes additional notes related to coding in various countries. (2020-05-29)Publication Metadata only Twenty Years of CJEU Jurisprudence on Citizenship(Cambridge University Press, 2014) de Groot, René; Luk, Ngo ChunThe history of the European Union has been fraught with constant friction between the sovereignty of the Member States and the supranational powers of the Union, with the Union gaining terrain in fields of law traditionally belonging to the Member States. Despite this tension, certain legal fields are steadfastly asserted as belonging to the Member States. Notably, Member States regulate the grounds of the acquisition and loss of nationality. The Treaty of Lisbon highlights that the nationality of Member States is scarcely governed by European Union law, if at all. The sole provision governing the relationship between Member State nationality and Union law, i.e., Article 20 of the Treaty on the Functioning of the European Union (TFEU) stresses the primacy of Member State nationality. Reality, however, is often not as simple as such a cursory reading implies. European Union citizenship, once a mere complementary facet of the national citizenships, has transformed into an institution in its own right, forming a symbiotic relationship between the Member State nationality and the European Union.Publication Metadata only Geslachtsnaamswijziging(Boom Juridisch Tijdschriften, 2013) Gielen, Miranda; de Groot, RenéIn het Koninkrijk der Nederlanden bestaan een aantal verschillende naamrechtssystemen.
