The law allows Indian government to limit employment opportunities, freedom of association, and a foreigner’s possessions. These pieces of legislation also restrict movement inside India and prohibit select activities, most of which are political. In fact, Tibetan refugees are only allowed in India on the condition that they abstain from political protests against China – a clear suppression of their right to political expression as afforded by the UDHR. This political suppression was particularly evident during the 1991 visit of then Chinese Prime Minister Li Peng, during which Tibetan refugee leaders were arrested and placed under police surveillance to curtail protests. A similar occurrence was witnessed during Prime Minister Wen Jiabao’s 2010 visit. Human rights law grants refugees fundamental civil and political rights, yet the Indian government denies these rights to Tibetan refugees.
India’s lack of legal obligation allows it to alter refugee policies at will, often to reflect its current political interests. The result is a rather unstable refugee policy, exemplified in the disparity of rights and services afforded to Tibetan refugees according to their date of arrival in the country.
