All schools are officially government-run and non-sectarian, although in practice some schools are run by the Christian and Druze communities. There is mandatory religious instruction in schools for all religious groups, with government-approved teachers and curriculum. Religious instruction is provided on Islam and Christianity only, and courses are divided into separate classes for Muslim and Christian students. Groups that participate in Islamic courses include Sunni, Shi'a, Alawi, Ismaili, Yezidi, and Druze. Although Arabic is the official language in public schools, the government permits the teaching of Armenian, Hebrew, and Aramaic in some schools on the basis that these are "liturgical languages." There is no mandatory religious study at the university level. Religious groups are subject to their respective religious laws for matters dealing with personal status. Syria has not yet passed legislation pertaining to personal status issues for Orthodox Christians. A new Civil Law for Catholics went into effect in 2006. It contains strict rules on the order of inheritance with regard to the relatives of the deceased, as well as on the jurisdiction of Christian courts. Additionally, there are laws that establish the legal marriage age and prohibit some instances of mixed marriage for Catholics, according to AsiaNews, the official press agency of the Roman Catholic Pontifical Institute for Foreign Missions. The law gives the bishop of a diocese and the Christian courts expanded authority to determine the validity of an adoption. The new law also clarifies parental rights and inheritance rules between adopting parents and the adopted child. The Catholic leadership generally received the law positively. Syrian law specifically provides for reduced or commuted sentences in "honor crimes", which involve violent assaults by a direct male relative against a female. Section 548 of the Syrian penal code stipulates that a man can be absolved of any killing if he witnesses a direct female relative in the act of adultery. Moreover, a man's sentence for murder will be greatly reduced if he sees a direct female relative in a "suspicious situation" with a member of the opposite sex who is not a relative. Under Syria's interpretation of Shari'a, the legal standard for men to be granted a divorce is much lower than that for women. Husbands may also claim adultery as grounds for divorce, while wives often face a higher legal standard when presenting the same case. A man can only be found guilty of adultery if the act takes place inside the home. If a wife requests a divorce from her husband, she may be denied alimony and the return of her dowry in some instances.
