International Sources of Law—Important sources of law include the laws of the individual
countries, treaties and trade agreements among those countries, and the rules enacted by
international organizations such as the UN, WTO and CISG. Congress must vote to approve
treaties with other nations.
Add. Info: Alternative Legal Traditions—Generally, there are three major ‘families’ of legal
systems: (1) common law, (2) civil law, and (3) religious law. They are not mutually exclusive.
The U.S. may be viewed as a common law system, but the civil and criminal codes play huge
roles. Similarly, precedents are followed in civil law countries. A summary:
Civil Law—The basic source of law are codes; most disputes are resolved by looking to a statute
or code. In contrast to the common-law systems where basic laws are developed by judges, the
codes of conduct are enacted by the government. Judges play a greater role in proceedings—
questioning witnesses and conducting the court proceedings—than their common law
counterparts. Major civil law countries include: Japan, Germany, France, Mexico, and Italy.
Religious Law—Within Islam and Judaism the law is asserted to be the word of God. Generally,
the laws affecting personal relations are derived directly from religious doctrines. The sources of
law are the religious writings—for example, the Qur’an in the Islamic legal system and the
Torah in the Jewish legal system. The commercial laws in some religious law countries have
been adapted from Western codes to assist economic development.
CLASSIFICATIONS OF LAW—The law could be classified in several ways, including: by its
source, or according to whether it could be classified as being private or public law, civil or
criminal law; or, substantive or procedural law. It is important to note that these categories are
not mutually exclusive. For example, a law could be private, civil and substantive.
Private and Public Law—Public law is concerned with the legal relationships between society
members and the government (or other) authority. Private law sets forth the legal relationships
among society members.
Civil and Criminal Law—Civil law is concerned with the rights and duties that exist among
individual society members, or between society members and the government (or other)
authority in noncriminal matters. Civil law requires that the wrongdoer be found liable by a
preponderance of the evidence. Criminal law concerns legal wrongs, or crimes, committed
against all of society. Criminal law requires that the wrongdoer be found guilty beyond a
reasonable doubt. One area of criminal law is white collar crime, particularly computer-related
crime.
Add. Case: Werner, Zaroff v. Lewis (Civ. Ct. of N.Y.C., 1992). Background: The plaintiff, a law
firm, hired Lewis to work on its computer system. When the firm made its last payment to Lewis,
he said to an attorney that if the firm had not paid he would crash the system. When the
computer reached job number 56789 the system crashed. A consultant determined that Lewis
caused the crash. The firm sued Lewis. The trial court found for the plaintiff and Lewis
appealed.
