The sources of constitutional law in foreign countries are regulations that provide rules governing constitutional and legal relations. The main source of this branch of law in most countries (with the exception of some Muslim countries) is the constitution - the fundamental law. Other sources include:
1) Laws - Constitutional (make changes in the constitution or complement), organic (made in a more complex manner and is usually controlled an institution of constitutional law in general), common (regulate certain issues, such as the law on presidential elections), emergency (according to the constitution itself, these laws may derogate from its provisions, but accepted only for a short time, usually several months, although with the right of Parliament to extend this period);
2) domestic public law contracts (for example, the National Pact in 1943 in Lebanon on the distribution of top government posts among adherents of different religions, the agreement on the division of Czechoslovakia from January 1, 1993 into the Czech Republic and Slovakia, the Constitutional Agreement between the President and the Parliament of Ukraine 1995 the Constitutional Treaty in 1996 between Moldova and the breakaway republic of Transnistria that the latter remains a republic within Moldova);
3) The regulations of parliaments and their chambers, the internal organization and procedure of the parliament. They are taken either in the form of resolution of each House for themselves and do not require approval by the other chamber (Germany) or in the form of law in the unicameral parliament (China);
4) acts of the President and the executive (the decrees of monarchs, presidents decrees, government regulations, acts of ministers, some departments, such as the decision of the Central Electoral Commission on compiling lists of voters). The special role of executive acts belongs to acts having the force of law (they are issued based on the following consideration by Parliament delegation (as, for example, in the UK), or on the basis of the Constitutions of Government-owned by the regulatory authorities (Italy), or under the exclusive authority President (France);
5) acts of constitutional control (constitutional courts, constitutional councils, etc.) that give the official interpretation of the Constitution, which recognizes those or other relevant laws or to the Constitution;
6) court cases (especially in Anglo-Saxon law) - solutions high-level judges, published them, and becoming the basis for the adoption of similar decisions by other courts in such cases. In some countries, legal precedents are not recognized as sources of law, that is, in essence, are not precedents. In France, the Civil Code prohibits the courts to formulate the law, but they do it, especially in the field of administrative law, such rules creates and the Constitutional Council, in particular on the rights of the individual;
7) constitutional convention - the prevailing practice in the uniform of a rule of the State having oral character, based on consensus (agreement) of the participants relationship and do not enjoy legal protection in the event of breach. Manners are especially prevalent in the work of the parliament and government of Great Britain, New Zealand, where there is no written constitutions;
8) religious sources, especially with the feudal monarchic states and tribal remnants, in particular on the issue of succession. In a few Muslim countries, the constitution replaces the Quran - holy book, containing, according to legend, writing sermons of the Prophet Muhammad, in others the Koran is considered to be an act of standing above the Constitution;
