Constantine sued Greece at the European Court of Human Rights for €500 million in compensation for the seized property. He won a much smaller amount, receiving a monetary compensation of €12 million for the lost property, with a far smaller sum awarded to his unmarried younger sister, Princess Irene , and his aunt Princess Katherine . 
Greece became a member of the European Union in 1981. Greece had seen rapid growth in the 1990s, but some of the country's economic statistics were modified to appear more correct than they were, as the government had lied with the help of banks from the United States. In 2004, Greece hosted the Olympic Games for a second time.
