The Universal Declaration of Human Rights, which has been signed by most countries, says:
(1) Everyone has the right to seek and to enjoy in other countries asylum from persecution.
(2) This right may not be invoked in the case of prosecutions genuinely arising from non-political crimes or from acts contrary to the purposes and principles of the United Nations.
In Canada, it seems, this right has been respected even when it seems contrary to Section (2) above: Row as Canada gives asylum to white South African | World news | The Guardian
Asylum seeker Brandon Huntley claimed he had been persecuted, abused and repeatedly stabbed. But it was the reason he gave for his ordeal that caused a diplomatic rift today. Huntley is South African – and white.
Canada's decision to grant him refugee status because of his colour prompted accusations of racism from the South African government and a fresh bout of soul searching in a country still scarred by the legacy of apartheid. Some South African whites say they have become a persecuted minority.
But France refused asylum to Vladimir Popov, Yekaterina Popova and their two children, who claimed that they were persecuted in Kazakhstan because they were Orthodox Christians and ethic Russians. French authorities kept them in detention for two weeks and repeatedly tried to deport them to Kazakhstan. That seems to be in line with the treatment of asylum seekers in Australia and, in some cases, South Africa.
But in this case the European Court of Human Rights disagreed Interfax-Religion
The European Court of Human Rights found France guilty of violating Article 3 (prohibition of inhuman or degrading treatment), Article 5 (right to liberty and security) and Article 8 (right to respect to private and family life) of the European Convention on Human Rights, and ordered France to pay the family 13,000 euros.So here are five different countries -- Australia, Canada, France, Kazakhstan, and South Africa -- on five different continents, with very different attitudes to asylum seekers and asylum seeking. For some seeking asylum is a human right, for others it is a crime.
