Greece is the only country in the European Union that allows the implementation of the Sharia, the muslim religious law. This is based on the 1923 Treaty of Lausanne governing the status of the muslim minority of Western Thrace or rather a convenient, (for various reasons both for the Greek State and the Muslim Minority), interpretation of the Treaty. Still recently the Court of First Instance, (Πρωτοδικείο), of Rodopi has overturned a decision by an islamic court stating that :
“the prerogatives of the mufti (…) cannot act towards the direction of violating the personal/civil rights of muslim women“
The case regarded the inheritance that was to be assigned to a daughter and was half of what the son would perceive. It is the first of it’s kind and opens up the way to the abolition of the practice since it directly challenges the decision of the mufti. You can read an article on the greek Sharia by Ios but I’d also recommend reading an interesting dialogue at e-roosters.
