Oxford BA: Natural Law & Legal Positivism Exam Paper

The Republic of Moralia has recently enacted the 'Public Order Act 2024', which criminalises all forms of public protest and assembly without prior government approval. The Act was passed following proper parliamentary procedure and has received royal assent. Citizens challenging the law argue that it violates fundamental human dignity and natural justice, being inherently immoral and therefore legally invalid. The government responds that the law is necessary for national security and, having been validly enacted through constitutional processes, must be legally binding regardless of its moral content. Maria, a philosophy professor, organises a peaceful vigil for democracy and is arrested under the Act. Her lawyers argue the Act is 'contrary to natural law and therefore void'. The prosecution maintains that courts must apply validly enacted legislation regardless of moral considerations. Advise the court on how natural law and legal positivist theories would approach this case, considering the relationship between law and morality in determining legal validity.

Critically evaluate Hart's critique of natural law theory in 'The Concept of Law'. To what extent have contemporary natural law theorists successfully responded to Hart's objections?

The State of Legalis operates under a written constitution providing that 'Parliament shall have power to make laws for the peace, order and good government of Legalis.' The Constitution also states that 'fundamental human dignity shall be respected' but provides no enforcement mechanism. Parliament has validly enacted the 'Emergency Powers Act 2024' following constitutional procedures, which authorises indefinite detention without trial for persons deemed 'threats to national security' by executive determination. No judicial review is permitted. Ahmed, a journalist investigating government corruption, is detained under the Act. The detention order states merely 'Ahmed poses a threat to national security.' Ahmed's lawyers argue the Act violates fundamental human dignity principles inherent in the rule of law and is therefore invalid despite formal enactment. Government lawyers respond that courts must apply validly enacted legislation and cannot invalidate laws based on abstract moral principles not legally entrenched. Consider how different schools of legal positivism (Hart, Raz, soft positivism) and natural law approaches would analyse this case, particularly regarding the role of constitutional interpretation and the relationship between formal validity and moral content.

To what extent does Dworkin's theory of 'law as integrity' successfully bridge the divide between natural law and legal positivism? Critically assess whether his interpretive approach offers a convincing alternative to traditional jurisprudential categories.
