If they did not keep the promises of international law, this could only happen if those promises had also been incorporated into national law. Today, there are only a few countries whose legal system is exclusively religious. In contrast, a large number of countries have secular systems, and this characteristic can be incorporated into their legal structure, as in the French and Russian Constitutions of 1958 or the very first words of the First Amendment of the U.S. Constitution: “Congress must not enact a law that respects a religious community.” In States with a monistic system, international law does not need to be translated into national law. The act of ratifying an international treaty shall immediately incorporate that international law into national law. The ICC Statute can therefore be applied and decided directly before national courts. If someone did not keep the promises they made under an Act of the Scottish Parliament or an Act of the British Parliament that applies to Scotland, they would be violating national law and could therefore be brought before a Scottish court. Scottish law is the type of national law applied by Scottish courts. What is domestic is related to domestic use. A pet is an animal that is tame enough to live with a family, such as a dog or cat, or that can be used to help support a family, such as a cow, chicken or horse.

When something is domesticated, it is converted into domestic use, as in the case of a tame wild animal. Example: Holland – a monist system with implementing provisions In the first group, there are countries with a “mixed” system influenced by both civil and customary law. The old uncodified civil law of Holland forms the basis of the Romano-Dutch law of South Africa, Zambia, Namibia, Lesotho, Swaziland, Botswana and Sri Lanka; It is characterized by a rich legal literature, which comes from Hugo Grotius (de Groot) in the 17th century. But their long contacts with Britain mean that their public law and judicial systems owe much to the common law. Two common patterns are that of the president and that of the parliamentary system. The former merges ceremonial and political power into a single office, its holder being elected directly and quite separately from the legislative power: it is therefore quite possible (and common in the United States) that the president belongs to one party and that a majority of the legislature belongs to another. It separates the executive and legislative powers, so that neither body can dissolve the other: the president is only dismissable for serious crimes in which the legislator acts as a court. The president appoints ministers for confirmation by the legislature, but there is no collective responsibility of the cabinet. The President usually has a veto over laws, which can only be overturned by a special parliamentary majority. On the other hand, the decisive fiscal power remains in the hands of the legislator.

Private law defines who is considered a person capable of entering into legal relationships and deals with his or her legal capacity (to protect the very young or the mentally ill). These natural persons may create other “artificial” legal entities such as associations, foundations and companies. As a rule, there are few generalizations that can be made through different constitutions. First, constitutions seek to regulate the distribution of powers, functions and duties among the various agencies and government officials, and to define the relationship between them and the public. Second, no constitution, no matter how well designed, can protect a political system from effective usurpation. Third, those in power in many countries are more or less completely ignorant of the constitution. Fourth, even when constitutions work, none are complete: each works in a matrix of compromises, customs, or jurisprudence. Fifth, most begin by identifying (at least on paper) the constituent authority (such as “the people”) and often refer to the deity (i.e., Canada, Germany, Greece, Ireland, Pakistan, Switzerland). Sixth, they generally separate the legislative, executive and judicial branches of the State. Seventh, they usually contain or incorporate a bill of rights.

Eighth, they often provide a method for repealing laws and other instruments that are unconstitutional, including the Bill of Rights. Ninth, they address the international scene only in general and, in practice, they confer extensive powers on the (federal) executive. Finally, they deal with the status of international law by giving or denying it direct internal effect. Scotland, Louisiana, Mauritius and Quebec are examples of private law based on older civil and customary rules (not codified in Scotland) that must exist in a common law environment. Israel has its own system, in which the old layers of the Ottoman and British mandate are now replaced by a modern system. It does not have a single constitutional document, but much of modern law combines the great legislative simplicity of the major civil codes with the prudent transparency of the common law decision. Most modern legal systems can be described as common law, civil law, or a mixture of both. Although the length of constitutions varies widely, the greatest detail is usually devoted to the legislative and executive powers and the relationship between them. Federal systems, of course, have bicameral legislation.
