Law and justice

What you'll learn

• What “justice” means in law, and why it is not the same as simply “following the rules”.
• The main types of justice: formal, substantive, procedural, distributive, corrective and retributive.
• Key theories of justice, including Aristotle, natural law, legal positivism, utilitarianism and Rawls.
• How to evaluate whether the legal system produces just outcomes.

Starting point: law and justice are connected, but not identical

Law is a system of rules recognised and enforced by the state. Justice is about whether those rules, procedures and outcomes are fair.

A law can be legally valid but morally questionable. Equally, a result may feel “fair” in one case but create uncertainty or unfairness for future cases. That tension is why this topic sits in The nature of law.

The meaning of justice: different types

Justice is easier to analyse if you split it into types. The same legal situation may be just in one sense but unjust in another.

The map below shows the main ideas you can use as “lenses” when evaluating law and justice.

Formal justice

Formal justice means treating like cases alike and different cases differently. It is closely linked to consistency.

For example, two defendants who commit the same offence in similar circumstances should usually receive similar sentences. This supports certainty and equality before the law.

Substantive justice

Substantive justice asks whether the content or outcome of the law is morally fair.

For example, in R v R (1991), a husband was convicted of raping his wife; the House of Lords confirmed that marriage did not create permanent consent. This is often seen as substantively just because the common law adapted to equality and personal autonomy.

Procedural justice

Procedural justice is about fair process: a fair hearing, an impartial decision-maker and the chance to respond to evidence.

This links to Article 6 ECHR, which protects the right to a fair trial, and to s6 Human Rights Act 1998, which makes it unlawful for public authorities, including courts, to act incompatibly with Convention rights.

You may also see the phrase natural justice, meaning basic fairness in decision-making. Two classic principles are audi alteram partem — “hear the other side” — and nemo iudex in causa sua — “no one should be a judge in their own cause”.

Distributive justice

Distributive justice concerns the fair allocation of benefits and burdens in society. In law, this can include access to legal aid, protection for vulnerable consumers, and how public resources are distributed.

For example, s62 Consumer Rights Act 2015 makes unfair consumer terms not binding, which can be seen as helping to correct inequality between businesses and consumers.

Corrective justice

Corrective justice is about putting right a wrong. In civil law, damages aim to compensate the claimant.

In Donoghue v Stevenson (1932), a woman became ill after finding a snail in ginger beer; the House of Lords created the neighbour principle, requiring reasonable care towards those foreseeably affected. This supports corrective justice by giving injured people a remedy.

Retributive justice

Retributive justice focuses on punishment that is deserved and proportionate to wrongdoing.

In criminal sentencing, s142 Criminal Justice Act 2003 lists purposes of sentencing, including punishment, crime reduction, rehabilitation, public protection and reparation. These aims can pull in different directions.

Theories of justice

A theory of justice is a way of explaining what fairness should mean. You do not need to learn every philosopher in detail, but you should be able to use a few theories to analyse law.

Aristotle: treating like cases alike

Aristotle is linked with formal justice: like cases should be treated alike, and unlike cases should be treated differently in proportion to their differences.

This affects how law is conducted through precedent, sentencing guidelines and consistency in decision-making. It supports the rule of law, but it may not fix an unjust rule.

Natural law

Natural law theory says law should be connected to morality. In simple terms, a seriously unjust law lacks moral authority.

Natural lawyers are likely to ask whether law protects basic human dignity, equality and fairness. Human rights law often reflects this approach.

Legal positivism

Legal positivism says the validity of law depends on its recognised legal source, not whether it is morally good.

A positivist might say an Act of Parliament is valid law if passed correctly, even if it is harsh. This supports certainty, but it can seem unsatisfactory when the law produces morally troubling results.

Utilitarianism

Utilitarianism judges rules by their consequences, especially whether they produce the greatest overall happiness or welfare.

This can justify laws aimed at public safety, deterrence or efficiency. The weakness is that it may allow serious unfairness to individuals or minorities if the majority benefits.

Rawls: justice as fairness

John Rawls argued that fair principles are those people would choose from behind a veil of ignorance, meaning they do not know their own status, wealth, gender, ability or position in society.

This encourages laws that protect basic liberties and support the least advantaged. It is useful when discussing legal aid, equality and access to justice.

To what extent does law achieve justice?

This is the key evaluation question. The legal system does produce many just outcomes, but not perfectly.

Ways law can achieve justice

The law supports justice through the rule of law, meaning state power should be exercised according to clear legal rules rather than arbitrary decisions.

It also supports procedural justice through fair trial rights. In A v Secretary of State for the Home Department (2004), foreign terror suspects were detained indefinitely without trial; the House of Lords made a declaration under s4 Human Rights Act 1998 that the scheme was incompatible with Article 5 ECHR and Article 14. This shows courts can identify injustice even in national security cases.

The criminal law can adapt to fairer fault principles. In R v G (2003), two boys accidentally caused a major fire after lighting newspapers; the House of Lords rejected objective recklessness for criminal damage and restored subjective recklessness, making liability depend more closely on what the defendant actually foresaw.

Civil law can also achieve corrective justice. Negligence claims, consumer protection and damages all aim to provide remedies where one party has been wronged.

Ways law may fail to achieve justice

Access to justice is a major problem. If a person cannot afford advice or representation, rights may exist “on paper” but be hard to enforce. s9 and Sch 1 Legal Aid, Sentencing and Punishment of Offenders Act 2012 reduced the scope of civil legal aid, although s10 LASPO 2012 allows exceptional case funding in limited situations.

Legal certainty can also conflict with individual justice. Courts often follow established rules so that the law is predictable. But a predictable rule may still produce a harsh result in a particular case.

Public interest may conflict with individual rights. For example, Article 10 ECHR protects freedom of expression, but it is a qualified right, so restrictions may be justified for aims such as national security, public safety or protecting the rights of others. Proportionality means the restriction should go no further than necessary.

Building an AO3 evaluation

For OCR, your evaluation should not be a vague opinion. Use this structure:

• AO1: define the type or theory of justice accurately.
• AO2: connect it to a legal example, case, statute or scenario.
• AO3: weigh both sides and explain your judgement.

A strong final judgement might say: law achieves justice best when rules are clear, rights are enforceable, processes are fair and remedies are accessible. It achieves justice less well where cost, delay, rigid rules or unequal power prevent people from using the law effectively.
