1. Common-law systems are based on case law - that is,
on court decisions. This is a system in which legal
decisions are based upon decisions in previous cases
and on custom, rather than on detailed written law.
Judges based their decision on legal precedents. They
could also overrule any precedents that they
considered to be an error or outdated. The common
law is law made by judges.
2. Civil-law systems are based mainly statutes. These
statutes organized collections called codes. Most
modern law codes can be traced back to the famous
code commissioned by the roman emperor Justinian I.
In civil law countries, such as France, Germany,
Mexico, the statutes, not the court, provide the final
answer to any question of law.
3. The source of the religious system of law is the will of
God, which is expressed in sacred texts and
commandments. A special feature of religious law is
that it unites people of the same faith. Religious law
consists of moral principles that regulate the life of
society. There are nowadays few countries with
religious system.
4. Traditional law is based on an unwritten and long-
standing tradition. This system is characteristic of
primitive society, and in our time there is not a single
state in which there would be a traditional system of
law in its purest form.
5. The English law is based on case law correctly on law
made by judges. Besides, English law consists of
statutes, but these statutes don't apply to civil l and
commercial law. English law dates from the time
immemorial.
