'''Jus soli''' (
Latin for "right of the soil" or, somewhat figuratively, "right of the territory"), or '
birthright citizenship', is a
right by which
nationality or
citizenship can be recognised to any individual born in the territory of the related state. At the turn of the nineteenth century,
nation-states commonly divided themselves between those granting nationality on the grounds of ''jus soli'' (
France, for example) and those granting it on the grounds of ''
jus sanguinis'' ("right of blood") (
Germany, for example). However, most European countries chose the German conception of an "objective nationality", based on "blood", "
race" or
language (as in
Fichte's classical definition of a nation), opposing themselves to
republican Ernest Renan's "subjective nationality", based on an every-day
plebiscite of one's appurtenance to his
Fatherland. This non-
essentialist conception of nationality allowed the implementation of ''jus soli'', against the essentialist ''jus sanguinis''. However, today's massive increase of
refugees has somewhat blurred the lines between these two antagonistic sources of right.
''Lex soli''
Usually a practical regulation of the acquisition of nationality or citizenship of a state by birth on the territory of the state is provided by a derivative
law called ''lex soli''. Most states provide a specific ''lex soli'', in application of the respective ''jus soli'', and it is the most common means of acquiring nationality. A frequent exception to ''lex soli'' is imposed when a child was born to a parent in the diplomatic or consular service of another state, on a mission to the state in question.
Blurred lines between ''jus soli'' and ''jus sanguinis''
Some countries are restricting ''lex soli'' by requiring that at least one of the child's parents be a national of the state in question at the child's birth, or a legal permanent resident of the territory of the state in question at the child's birth, or that the child be a
foundling found on the territory of the state in question. The primary reason for imposing this requirement is to limit or prevent people from travelling to a country with the specific intent of gaining citizenship for a child. The
27th amendment to the
constitution of the
Republic of Ireland was passed by
referendum in 2004 for this purpose.
Specific national legislation
''Jus soli'' is common in countries in the New World that wanted to develop and increase their own citizenry. It is also recognized in some Old World nations. Some countries that observe ''jus soli'':
★
Argentina
★
Barbados
★
Brazil
★
Canada
★
Colombia
★
Jamaica
★
Mexico
★
Pakistan
★
Peru
★
United States
★
Uruguay
Modification of jus soli
In a number of countries, the automatic application of ''jus soli'' has been modified to impose some additional requirements for children of foreign parents, such as the parent being a permanent resident or having lived in the country for a period of time. ''Jus soli'' has been modified in the following countries:
★
United Kingdom on
1 January 1983
★
Australia on
20 August 1986
★
Republic of Ireland on
1 January 2005
★
New Zealand on
1 January 2006
★
France also operates a modified form of ''jus soli''
German nationality law was changed on
1 January 2000 to introduce a modified concept of ''jus soli''. Prior to that date,
German nationality law was based entirely on ''
jus sanguinis''.
Modification of ''jus soli'' has been criticized as contributing to the growing global problem of statelessness, along with the creation of social underclasses and various legal challenges in countries like Australia. For example, in Australia, children must wait ten years before they are considered equal in the eyes of the law to their peers.
On the other hand, in places like the
United States, ''jus soli'' is credited with the nation's ability to integrate various nationalities and with much less social strife and difficulties than other countries. Although ''jus soli'' was formally stated in the
Fourteenth Amendment, judicial authorities recognize that the philosophy was integral at the conception of the country's constitution.
Abolition of jus soli
Some countries which formerly operated ''jus soli'' have moved to abolish it partially, only conferring citizenship on children born in the country if one of the parents is a citizen (or has been a legal resident for a number of years) of that country. These include:
★
India on
1 July 1987
★
Malta on
1 August 1989
★
Ireland on
24 June 2004
★
New Zealand on
1 January 2006
United States
Recently, due to the influx of
illegal immigrants, there have been moves (though unsuccessful, thus far) to abolish it in the United States. Amendment of
US citizenship law to remove ''jus soli'' would require either a Constitutional amendment or a reversal by the
Supreme Court. That is because the Fourteenth Amendment, as established in
United States v. Wong Kim Ark, guarantees and protects the citizenship of any individual born in the United States.

A minor, quite improper use of the term ''jus soli'' refers to the
jurisdiction: in this case it would indicate that the law to use is the law of the nation-state in whose territory the evaluated fact happened. But, as said, it is not considered a correct use of the term, or at least it is considered misleading.
