Which of these countries does not have the Constitution?

The State of Israel has an unwritten constitution. Instead of a formal written constitution, and in accordance with the Harari Decision (החלטת הררי) of 13 June 1950 adopted during the Israeli Constituent Assembly, the State of Israel has enacted several Basic Laws of Israel dealing with the government arrangements and with human rights. The Israeli Supreme Court President Aharon Barak ruled that the Basic Laws should be considered the state's constitution, and that became the common approach throughout his tenure (1995-2006).
