Law and justice: the meaning of justice and the main theories (Aristotle, Aquinas and natural law, utilitarianism, Rawls and Nozick), and the extent to which the legal system achieves justice.

What this dot point is asking

OCR Component 3 Section A requires you to explore justice: what it means, the main theories of it, and how far the legal system achieves it. Section A questions are extended-response evaluation essays (AO3), so the skill is to use the theories to build a critical argument and reach a judgement about the justice (or injustice) of the law.

The answer

The meaning of justice

The theories of justice

• Natural law (Aquinas). Law must conform to a higher moral order discoverable by reason. A law that conflicts with this order is unjust and, in the strong version, not a true law at all. This explains the idea that there are limits to what the state may justly command.
• Utilitarianism (Bentham, Mill). Justice is whatever produces the greatest happiness of the greatest number. It is practical and democratic, but it can justify sacrificing a minority for the majority's benefit, which many see as unjust.
• Rawls (justice as fairness). Principles of justice are those people would choose behind a veil of ignorance, not knowing their own place in society. This yields equal basic liberties and the difference principle: inequalities are just only if they benefit the least advantaged. Rawls justifies a welfare state, legal aid and redistribution.
• Nozick (justice as entitlement). Justice depends on how holdings were acquired and transferred; if justly acquired, they are the owner's by entitlement. Nozick favours a minimal state and strong property rights, with little redistribution, the opposite emphasis to Rawls.

How far the law achieves justice

The English legal system contains many mechanisms aimed at justice: the rule of law (everyone equal before the law), an appeals system to correct errors, judicial review of unlawful state action, the Human Rights Act 1998 protecting fundamental rights, and the presumption of innocence and burden of proof in criminal law.

Examples in context

A strong Section A answer threads the theories through the evaluation and ends with a clear judgement.

Try this

Q1. Explain the difference between distributive justice and corrective justice. [shown at the 10-mark level for revision; Section A questions are extended-response 20-mark essays]

• What the marker wants. Precise AO1 within an evaluative frame: distributive justice is the fair allocation of benefits and burdens across society; corrective justice is putting right a wrong between individuals, underlying tort and criminal punishment (Aristotle).

Q2. Evaluate the usefulness of Rawls's and Nozick's theories in understanding justice in the English legal system. [Section A extended-response evaluation, 20 marks]

• Cue. An AO3 evaluation: Rawls (the difference principle) explains legal aid and welfare protecting the worst off; Nozick (entitlement, minimal state) explains property rights and limited redistribution; weigh their competing emphases and judge which better illuminates the system.
