There are various theories of law, but four main ones are:
Natural Law Theory: This theory holds that
laws are based on universal moral principles that exist independently of human
laws and governments. It argues that these principles can be discovered through
reason and can be used to evaluate the validity of positive laws.
Positive Law Theory: This theory holds that
laws are created by human beings and are based on the will of the sovereign or
the state. Laws are valid because they are made by the proper authority, not
because they conform to any universal moral principles.
Legal Positivism: This is a theory of law
that holds that laws are created by human beings and are based on the will of
the sovereign or the state. Laws are valid because they are made by the proper
authority, not because they conform to any universal moral principles.
Realist Theory of Law: This theory holds that
laws are created by human beings, based on the will of the sovereign or the
state and are valid because they are made by the proper authority, not because
they conform to any universal moral principles. The realist theory also
emphasizes on the role of the judges and the court in interpreting the laws and
making them adaptable to the changing society.
Natural
Law Theory
Natural Law Theory is a legal theory that
holds that laws are based on universal moral principles that exist
independently of human laws and governments. According to this theory, these
principles can be discovered through reason and can be used to evaluate the
validity of positive laws.
Proponents of natural law theory argue that
there are certain basic principles of justice and morality that are common to
all human societies, and that these principles form the basis of all valid
laws. They believe that these principles are eternal and unchanging, and that
they are the foundation of all legal systems.
The natural law theory also holds that human
reason can be used to discover these principles, and that they can be used as a
guide for human conduct. In this way, natural law theorists argue that the law
should be based on objective moral principles, rather than the subjective will
of the sovereign or the state.
Critics of natural law theory argue that the
principles of natural law are too abstract and difficult to apply in practice,
and that they can be used to justify any kind of law or policy. They also argue
that natural law is often used as a justification for certain religious or
ideological beliefs, and that it can be used to justify oppressive or unjust
laws.
Positive Law Theory
Positive Law Theory is a legal theory that
holds that laws are created by human beings and are based on the will of the
sovereign or the state. According to this theory, laws are valid because they
are made by the proper authority, not because they conform to any universal
moral principles.
Proponents of positive law theory argue that
laws are created by human beings for specific purposes, such as maintaining
order and protecting the rights of individuals. They believe that laws are
valid because they are made by the proper authority, such as a legislature or a
court, and that they are binding on all members of society.
Positive law theory also emphasizes that the
law is a human construct and that it can be changed as society's needs and
values change. This view contrasts with the natural law theory which holds that
laws are based on eternal and unchanging principles.
Critics of positive law theory argue that it
can lead to laws that are arbitrary and unjust, since they are based solely on
the will of the sovereign or the state. They also argue that positive law can
be used to justify oppressive or unjust laws, since the validity of a law is
determined solely by its source, rather than its content.
Legal Positivism
Legal positivism is a theory of law that
holds that laws are created by human beings and are based on the will of the
sovereign or the state. According to this theory, laws are valid because they
are made by the proper authority, not because they conform to any universal
moral principles. Legal positivism emphasizes the separation between law and
morality, and argues that laws should be evaluated based on their source and
their form, rather than their content or their effects.
Proponents of legal positivism argue that
laws are a human construct and that their validity should be determined based
on their source. They believe that laws are valid if they are made by the
proper authority and that they are binding on all members of society. They also
argue that laws should be evaluated based on their form, rather than their
content, meaning that the process by which a law is made is more important than
the specific provisions it contains.
Critics of legal positivism argue that it can
lead to laws that are arbitrary and unjust, since they are based solely on the
will of the sovereign or the state, not on any moral principles. They also
argue that legal positivism can justify oppressive or unjust laws, since the
validity of a law is determined solely by its source, rather than its content.
It is important to note that there are
different versions of legal positivism, some of which incorporate elements of
natural law or morality into their theory. For example, some positivists argue
that while laws are valid based on their source, they can be evaluated based on
moral principles such as fairness and justice.
Realist Theory of Law
The Realist Theory of Law is a legal theory
that emphasizes the role of the judges and the court in interpreting the laws
and making them adaptable to the changing society. This theory holds that laws
are created by human beings, based on the will of the sovereign or the state
and are valid because they are made by the proper authority, not because they
conform to any universal moral principles.
Proponents of the realist theory argue that
laws are not fixed or objective, but rather are open to interpretation and
change. They believe that laws should be interpreted and applied in a way that
takes into account the changing needs and values of society. They also argue
that judges and courts play a crucial role in shaping the law through their
decisions and interpretations.
The realist theory also emphasizes that the
law is a human construct and that it can be changed as society's needs and values
change. This view contrasts with the natural law theory which holds that laws
are based on eternal and unchanging principles. The realist theory also
emphasizes that the law is not only about rules and principles but also about
the administration of justice and the protection of rights.
Critics of the realist theory argue that it
can lead to a lack of predictability and stability in the law and that it can
be used to justify any kind of law or policy. They also argue that the realist
theory can be used to justify oppressive or unjust laws, since the
interpretation of the laws is left to the discretion of the judges.
