States currently have laws which allow for automatic loss of nationality, the international legal principles which govern these grounds are examined in the following paragraphs. One relatively common ground for loss of nationality is where it is based on possession or acquisition of a foreign nationality. However, this justification for loss of nationality is becoming more rare, as people are migrating more frequently and States recognize that individuals may have enduring ties to more than one nation.94 In 1960, the voluntary acquisition of another citizenship led automatically to the loss of the citizenship of the country of origin in approximately one third of all countries.95 As of 2018, the number of States that allow citizens to acquire the nationality of another country without the automatic loss of nationality of their country of origin has grown to approximately seventy five percent.96 In line with this global trend, some LAS member States have laws which allow for dual citizenship. Despite the global movement towards laws which allow for multiple nationalities, many States, including some LAS member States, provide for loss of citizenship upon possession, acquisition of, or application for a foreign nationality. As per the principles outlined in the 1961 Convention, and otherwise widely accepted in complementary areas of international law, acquisition, possession of, or application to possess another nationality should never leave an individual stateless. If a provision prohibiting dual nationality exists or is enacted, States should ensure that they do not allow the withdrawal of nationality to take effect before an individual acquires another nationality, or, alternatively, that the loss of nationality is void if the individual concerned fails to acquire the new nationality within a fixed period of time, such as one year.97 States may also adopt this measure in relation to the voluntary renunciation of nationality. This precaution would help to ensure that women who renounce their citizenship in situations where they marry, or intend to marry, a foreign man are not left without a nationality. Many LAS member States have adopted positive measures to this effect.98 Another approach to ensure that individuals are not left without a nationality, is for States to provide for the facilitated reacquisition of nationality upon application by a former citizen. 43
