By tradition, deposed monarchs who have not freely abdicated continue to use their monarchical titles as a courtesy for the rest of their lives. Hence, even after Constantine II ceased to be "King of the Hellenes", it is still common to refer to the deposed king and his family as if Constantine II were still on the throne, as many European royal courts and households do in guest lists at royal weddings, as in Sweden in 2010, Britain in 2011 and Luxembourg in 2012. The Republic of Greece oppose the right of their deposed monarch and former royal family members to be referred to by their former titles or bearing a surname indicating royal status, and has enacted legislation which hinder acquisition of Greek citizenship unless those terms are met. The former king brought this issue, along with property ownership issues, before the European Court of Human Rights for alleged violations of the European Convention on Human Rights, but lost with respect to the name issue.
