Tunisian dinar
It is a criminal offence in Tunisia to import or export dinar. Every year, each citizen can convert into foreign currency up to 6,000 Tunisian dinars before departure from the country. Therefore, prices at duty-free shops are in convertible currencies such as euros, US dollars and British pounds. There are many converting ATMs in the country for tourists.
Constitution of Tunisia
The 1959 constitution declares Tunisia to be an independent state, governed by a three branch presidential parliamentary system. It bestows certain rights on the people, including the right of ownership and right to confidentiality in personal correspondence (excluding cases of suspected criminal activity). In addition, the constitution bestows various freedoms upon the people; some of these include freedom of opinion, expression, press, and organization. It establishes Islam as the official state religion, and Arabic as its official language.
