Quick Summary
- Legal theories significantly shape everyday legal decisions, influencing how laws are interpreted and enforced in landmark cases like Roe v. Wade (natural law) and Riggs v. Palmer (legal positivism).
- Different legal theories can lead to vastly different outcomes in similar cases, as illustrated by scenarios where moral arguments versus strict legal interpretations affect sentencing.
- Grasping these foundational theories is crucial for anyone navigating the legal landscape, as they provide the framework for legal arguments and judicial decisions.
- There are six major legal theories—natural law, legal positivism, Marxist law, realist law, critical legal studies, and feminist jurisprudence—each offer unique perspectives on the nature and application of law.
The 6 Legal Philosophies That Shape the Law
There are three types of legal philosophy: analytic jurisprudence, normative jurisprudence, and critical law theories. Analytic jurisprudence determines what makes law different from other norms, such as morality.
Normative jurisprudence involves the evaluation of law from the perspective of whether it is just or efficient. Critical law theories concern how power is distributed within society through legal institutions.
There are 6 major legal theories: natural law, legal positivism, Marxist law, realism, critical legal studies, and feminist jurisprudence.
1. Aristotle's Natural Law Theory: Its Impact on the Founding Fathers
Natural law theory believes that a higher law is created by nature and applies to all human beings [1]. This legal theory was first proposed by the Greek philosopher Aristotle.
Natural law theory posits that inherent moral principles govern human behavior, which are universally applicable and can be discovered through reason.
The key idea behind natural law is an objective morality, moral obligation, moral principles, or a moral force independent of human opinion. This objective morality can be discovered through reason and is the foundation of all human laws, not legal rules.
Natural law theory has been influential throughout history, and many of the Founding Fathers of the United States were supporters of this theory.
One of the most famous proponents of natural law was Thomas Aquinas, who argued that four "universal" laws apply to all humans:
- The law of nature
- The law of reason
- The positive divine law
- The positive civil law
Real-World Example/Case Study
A significant application of natural law principles can be seen in the landmark case Roe v. Wade, where the U.S. Supreme Court recognized a woman's fundamental right to privacy, invoking natural law to support reproductive rights.
Natural Law in Today’s Debates
Natural law theory is intrinsically linked to human rights, as it posits that certain rights are inherent and universal, grounded like humanity itself.
The new legal rule gives judges and other officials an unknown reason to act (or not to act). The law also gives citizens a new reason to take action (or not to take action).
Critics of this legal theory argue that it is based on a false dichotomy between objective and subjective morality. They also say that natural law legal theory is too vague to be helpful in specific legal situations.
Natural law remains at the center of discussions on major issues like abortion, same-sex marriage, and human rights, with advocates arguing for laws grounded in universal moral values.
This law of nature, being co-eval with mankind and dictated by God himself, is of course superior in obligation to any other. It is binding over all the globe, in all countries, and at all times: no human laws are of any validity
- William Blackstone, English jurist, Judge, and Tory Politician
According to the Constitutional Rights Foundation, Aquinas believed that the first two laws (the law of nature and reason) were objective and could be discovered through reason [2].
The other two laws (the positive divine and the positive civil law) were created by humans and were not necessarily objectively true.
Applying Natural Law in Today’s Legal Practice
Lawyers today draw on natural law principles to challenge unjust laws, grounding their arguments in fundamental moral standards. This approach is especially relevant in constitutional cases where attorneys argue for rights and freedoms they believe should be universally upheld.
Natural law also serves as a foundation in human rights advocacy, often informing legal battles for dignity and equality.
In international law, natural law principles shape arguments for global standards of justice, including in cases related to environmental protection, where lawyers advocate for sustainable policies that respect the intrinsic rights of all beings.
Through these applications, natural law continues to guide legal efforts toward a fairer, more moral world.
2. Jeremy Bentham's Legal Positivism Theory: The Law of Human Creation
According to IEP, legal positivism believes there is no higher law than the law created by humans [3]. This legal theory was first proposed by the English philosopher Jeremy Bentham.
Bentham believed that humans make all laws and are not based on any objective morality. He also argued that the law aims to maintain order and social stability.
According to this legal theory, laws differ in different places and times. People who believe in this theory include Austin, Bentham, and H.L.A Hart.
These philosophers think that law is a command from the government to the people, and it has three parts: the command, the government, and the people. The government is the one who makes the law, and the people have to follow it, establishing a legal system.
Types of Positive Law
- Strong Positive Law: This view holds that the legitimacy of a law comes solely from the fact that it was made by the government, regardless of any moral considerations.
- Weak Positive Law: This approach allows for the idea that a law can be morally good even if the government didn’t create it.
Support and Criticism of Positive Law Theory
- Supporters believe positive law is appealing due to its simplicity, as it avoids the need to use morality to assess the value of a law.
- Critics argue that this simplicity is also a weakness, as it overlooks the potential for laws to be unjust and lacks depth in legal reasoning.
Role of Sanctions in Legal Compliance
Sanctions encourage people to obey the law by providing consequences for non-compliance. While some follow the law to achieve expected rewards, others obey even without direct rewards, reflecting varied motivations for compliance.
Real-World Example/Case Study
In the case of Riggs v. Palmer, the court ruled against a murderer inheriting from his victim, demonstrating how legal positivism can lead to outcomes that prioritize societal order over moral considerations.
Legal Positivism in Today’s Debates
This theory has led to the establishment of clear legal codes and frameworks that govern behavior without relying on moral judgments.
Even though all positivists agree that there are possible legal systems without moral constraints on legal validity, there are different views on whether it is possible to have a legal system with moral constraints.
Applying Legal Positivism in Today’s Legal Practice
Legal positivism is applied in contemporary legal systems where laws are strictly interpreted based on written statutes rather than moral implications. Lawyers utilize legal positivism by arguing based on statutory language and established precedents, focusing on the letter of the law rather than ethical considerations.
3. Marxist Law Theory: A Tool for Oppression or a Path to Justice?
Marxist law is a legal theory that Karl Marx created. Marx was a German philosopher who lived in the 19th century. He is best known for his theories about economics and politics.
According to SagePub, Marx believed that the law is a tool the ruling class uses to oppress the working class. He argued that the law is not objective or neutral but is biased in favor of the ruling class [4].
Marx believed the only way to achieve justice was to overthrow the ruling class and create a classless society.
Real-World Example/Case Study
The analysis of labor laws through a Marxist lens reveals how legislation often favors corporate interests over workers’ rights, as seen in various labor disputes across industries.
Marxist Law in Today’s Debates
This theory has influenced discussions around economic justice and reforming laws disproportionately affecting marginalized communities.
The legal theory assumes that people can achieve perfect equality when communism is reached. This has not been proven yet, as evidenced by the failed attempts in countries like the former United Soviet Socialist Russia (U.S.S.R.). However, this theory is challenged, and private property theory is gaining ground.
Some people think Marxist law is a good theory because it explains why some laws are unfair and provides a way to change them.
Critics of Marxist law argue that it is too radical and does not consider that some laws are necessary to maintain order in society.
Applying Marxist Law in Today’s Legal Practice
Contemporary activists use Marxist principles to critique social justice issues, advocating for reforms that address systemic inequalities perpetuated by existing legal frameworks.
4. Realist Law Theory: The Ever-Evolving Nature of Judicial Decisions
The realist law theory is interested in how the law works rather than its traditional definitions. Under this law theory, the law is based on judicial decisions in the court. The theory holds that rules that are not used to solve practical cases are not laws but merely exist as words on paper. These dead words of law only become alive when used to solve a dispute between two parties.
Real-World Example/Case Study
Obergefell v. Hodges (2015) legalized same-sex marriage nationwide, recognizing marriage as a fundamental right under the Fourteenth Amendment.
This decision reflects a realist approach by acknowledging the evolving social norms and personal impacts on same-sex couples rather than strictly adhering to traditional legal interpretations.
Justice Kennedy’s opinion highlighted how denying marriage rights affected dignity and equality, demonstrating that the Court considered real-world experiences and societal changes.
Realist Law in Today’s Debates
Realists believe that the law is constantly changing and evolving. They argue that today's law may not be the law tomorrow. This is because new cases are continually being decided by a judicial decision in court, which can change the law and legal practice.
This theory is based on the common law legal system. In this system, the decision made by a court in a previous case is used as a guide to decide future similar cases.
However, based on what I see in my practice, this theory does not apply in the civil law legal system. This is the other primary legal system globally, and it is different because it is based on a written code of law.
This theory suggests that the lawmaker in the civil law legal system is not the judge. The people who believe this theory include Justice Homes, Lawrence Friedman, John Chipman Gray, Jerom Frank, Karl N. Llewellyn, and Yntema.
Applying Realist Law in Today’s Legal Practice
This approach has led to more adaptive legal interpretations that reflect changing societal values and realities.
Realist principles guide judges and lawyers in interpreting laws based on their practical implications rather than rigid adherence to texts.
The function of realist jurisprudence…is not to make the law but to describe how it works
- Justice Benjamin N. Cardozo, American Lawyer, and Jurist
5. Critical Legal Studies: Unmasking the Power Dynamics Behind the Law
According to Law Cornell, the CLS movement tries to expand the realism of law into a critique of mainstream jurisprudence from a Marxist perspective [5].
Some people think that the realists do not understand how much indeterminacy there is in law. The realists believe that this indeterminacy is only in some instances.
Real-World Example/Case Study
CLS Law in Today’s Debates
This movement has prompted re-evaluations of various laws and policies through a lens that prioritizes equity and justice over traditional legal interpretations.
The CLS movement believes that the law is not neutral. They say that the law supports the interests of those in power. This theory is based on the work of Karl Marx. He argued that the law was a tool that was used by the ruling class to keep their power.
The CLS movement has been criticized for being too radical. Some people say their theory does not consider that some laws are necessary to maintain societal order.
Applying CLS Law in Today’s Legal Practice
Critical Legal Studies (CLS) encourages courts to consider the broader social impacts of their rulings, especially on marginalized groups.
Though not always directly cited, CLS perspectives are evident in cases addressing systemic racism and economic inequality.
This approach has influenced civil rights, environmental, and family law by challenging existing power structures.
In practice, lawyers involved in social justice often apply CLS principles to contest unjust laws and push for meaningful reforms that address underlying societal issues.
6. Feminist Jurisprudence: How the Law Impacts Women's Rights and Equality?
Feminist legal theory is interested in how the law affects women. This theory says that the law is not neutral. It isn't very objective against women. This theory is based on the work of feminists like Catharine MacKinnon, Robin West, and Deborah L. Rhode.
Real-World Example/Case Study
Feminist Jurisprudence Law in Today’s Debates
Feminist legal theories inform contemporary debates around reproductive rights, workplace discrimination, and domestic violence legislation.
The majority of early feminist legal theorists adopted a discrimination model to the issue of gender. Their objective was to outlaw biased treatment and provided laws that allowed women equal opportunities with men
- Martha Albertson Fineman, American Jurist, Legal Theorist, and Political Philosopher
Key Differences Between Legal Theories
