Under the separation of powers doctrine, no branch of government may exercise a power of government assigned exclusively to another branch.

Some issues of family law (marriage and divorce in particular) fall either under the jurisdiction of religious courts or under parallel jurisdiction of those and the state's family courts. The state maintains and finances Rabbinical, Sharia and various Canonical courts for the needs of the various religious communities. All judges are civil servants, and required to uphold general law in their tribunals as well. The Supreme Court serves as final appellate instance for all religious courts.
