HSC Legal Studies 2023

Question 1 (5 marks): At a 21st birthday party, Declan (22) and Marcus (24) argue. Marcus shoves Declan and then picks up a glass bottle and raises it above his head. Declan punches Marcus once, splitting his lip and bruising his cheek. Police charge Declan with assault occasioning actual bodily harm. (a) Identify the actus reus and mens rea the prosecution must prove. (2 marks) (b) Explain whether Declan could rely on self-defence. (3 marks)

Step 1: The elements (part a)

• Actus reus (the physical element): Declan applied force to Marcus by punching him, and that act caused actual bodily harm, here the split lip and bruising, which are more than trivial or transient injuries.
• Mens rea (the mental element): Declan intended to strike Marcus, or was reckless as to applying force. The prosecution must prove both elements beyond reasonable doubt. The offence is found in s 59 of the Crimes Act 1900 (NSW).

Step 2: The law of self-defence (part b)

Self-defence in NSW is set out in Part 11 Division 3 of the Crimes Act 1900 (NSW). Under s 418, a person is not criminally responsible if they believed the conduct was necessary to defend themselves, and the conduct was a reasonable response in the circumstances as they perceived them. Under s 419, once there is evidence raising self-defence, the prosecution bears the onus of proving beyond reasonable doubt that the accused did not act in self-defence.

Step 3: Apply to the facts

• Belief (subjective): Marcus had already shoved Declan and then raised a glass bottle, which supports a genuine belief that Declan was about to be seriously hurt.
• Reasonable response (objective, judged on Declan's perception): a single punch against a man raising a bottle is proportionate. The case would be weaker if Declan had kept hitting Marcus after the threat ended, or had walked over to Marcus after he put the bottle down.
• Result: self-defence is a complete defence, so if the prosecution cannot exclude it, Declan is acquitted.

Final answer: (a) The prosecution must prove Declan applied force that caused actual bodily harm (actus reus) with intent or recklessness (mens rea) under s 59 of the Crimes Act 1900 (NSW). (b) Declan has a strong self-defence argument under s 418 because he genuinely believed force was necessary against an armed aggressor and one punch was a reasonable response; under s 419 the prosecution must disprove this beyond reasonable doubt, and if it cannot, he is acquitted.

Question 2 (4 marks): Explain how international human rights instruments and bodies can influence Australian domestic law. Refer to an example.

Step 1: The mechanism

Australia is a sovereign state, so treaties it signs and ratifies do not automatically become part of domestic law. They bind Australia internationally, but they are only enforceable in Australian courts once Parliament passes legislation implementing them. The Commonwealth's external affairs power in s 51(xxix) of the Constitution allows it to legislate to give effect to treaty obligations.

Step 2: The role of treaty bodies

Treaty bodies such as the UN Human Rights Committee monitor compliance with instruments like the International Covenant on Civil and Political Rights (ICCPR). Under the First Optional Protocol, individuals can lodge communications against a state that has accepted it. The Committee's views are not binding, but they create diplomatic and political pressure to reform.

Step 3: Example

In Toonen v Australia (1994), the Human Rights Committee found that Tasmanian laws criminalising consensual sexual activity between adult men breached the right to privacy in Article 17 of the ICCPR. The Commonwealth responded with the Human Rights (Sexual Conduct) Act 1994 (Cth), and Tasmania later repealed the offending provisions. The example shows international bodies can drive change, but only through the willingness of domestic governments to legislate.

Final answer: International instruments influence Australian law indirectly: they must be implemented by Commonwealth legislation (relying on the external affairs power), and treaty bodies apply non-binding pressure, as in Toonen v Australia, which led to the Human Rights (Sexual Conduct) Act 1994 (Cth).

Question 3 (25 marks, Family option): Evaluate the effectiveness of the legal system in resolving parenting disputes after separation.

Plan: thesis first

State a clear judgement in the introduction and return to it in every paragraph. Use criteria such as protection of the child, accessibility (cost and delay), and safety for victims of family violence.

Paragraph 1: The legal framework and the best interests principle

• The Family Law Act 1975 (Cth) makes the best interests of the child the paramount consideration in parenting orders.
• The Family Law Amendment Act 2023 (Cth), commencing in May 2024, removed the presumption of equal shared parental responsibility and simplified the best interests factors, with an express focus on the child's safety.
• Evaluation: the reform responds to evidence that the presumption was misread as a right to equal time, which could expose children to unsafe arrangements. This is an effective change in principle, though its impact is still being assessed.

Paragraph 2: Family dispute resolution

• Section 60I of the Family Law Act 1975 (Cth) generally requires parties to attempt family dispute resolution and obtain a certificate before applying for parenting orders, with exceptions for family violence and child abuse.
• Evaluation: mediation is cheaper, quicker and less adversarial, and agreements are more likely to be followed. It is less effective where there is a power imbalance, which is why the exceptions matter.

Paragraph 3: The courts

• The Federal Circuit and Family Court of Australia was created in 2021 to merge the two federal family courts and reduce delay.
• Evaluation: litigation remains slow and expensive, legal aid is limited, and self-represented parties are common, which weakens access to justice.

Paragraph 4: Family violence

• Family violence is the key challenge. State apprehended violence orders under the Crimes (Domestic and Personal Violence) Act 2007 (NSW) sit alongside federal parenting orders, and the two systems do not always align.
• Evaluation: the 2023 reforms improve the focus on safety, but coordination between state and federal jurisdictions remains a weakness.

Conclusion

Weigh the strengths against the weaknesses and restate the judgement in one sentence.

Final answer: The law is largely effective in principle, since the best interests principle, compulsory family dispute resolution and the 2023 removal of the equal shared responsibility presumption all put the child first, but it is only partly effective in practice because cost, delay and poor coordination between the state and federal systems on family violence still limit access to justice.

Question 4 (25 marks, Workplace option): Evaluate the effectiveness of legal and non-legal responses to sexual harassment at work.

Plan: thesis first

Argue that the law has shifted from a complaint-driven model to a preventive one, which makes it much stronger on paper, but that its effectiveness still depends on victims being willing to come forward. Criteria: prevention, remedies for victims, enforcement and accessibility.

Paragraph 1: Sexual harassment as unlawful discrimination

• The Sex Discrimination Act 1984 (Cth) makes sexual harassment in the workplace unlawful, and the Anti-Discrimination Act 1977 (NSW) provides a state avenue.
• Complaints go first to conciliation (the Australian Human Rights Commission federally, Anti-Discrimination NSW at state level), and only unresolved matters reach a court or tribunal.
• Evaluation: conciliation is cheap, private and quick, but it puts the burden on the individual victim and outcomes are usually confidential, which limits their deterrent effect.

Paragraph 2: Remedies and changing community values

• In Richardson v Oracle Corporation Australia Pty Ltd [2014] FCAFC 82, the Full Federal Court raised the damages from $18 000 to $130 000, holding that the original award did not reflect current community standards.
• Evaluation: higher damages make litigation more worthwhile for victims and signal that the law responds to changing values, but court action remains costly and stressful.

Paragraph 3: Law reform after Respect@Work

• The Australian Human Rights Commission's Respect@Work report (2020) found the complaint-based system was not working and recommended a preventive approach.
• The Anti-Discrimination and Human Rights Legislation Amendment (Respect at Work) Act 2022 (Cth) imposed a positive duty on employers to take reasonable and proportionate measures to eliminate sexual harassment, and from 12 December 2023 the Commission gained powers to inquire into and enforce compliance with that duty.
• Evaluation: a positive duty moves responsibility from the victim to the employer, which is a major improvement. Its effectiveness depends on how actively the Commission uses its new powers.

Paragraph 4: Non-legal responses

• Unions, the media and workplace training and reporting policies raise awareness and encourage reporting, and media coverage has repeatedly driven inquiries and reform.
• Evaluation: these responses shape workplace culture more directly than the law, but they are voluntary and uneven across industries.

Final answer: Legal and non-legal responses to workplace sexual harassment are now substantially effective in principle, because the Respect at Work positive duty and higher damages since Richardson v Oracle shift the burden to employers, but only moderately effective in practice, since many victims still do not complain and enforcement of the new duty is still developing.

Question 5 (25 marks, Global Environmental Protection option): Evaluate the effectiveness of legal measures in responding to climate change.

Plan: thesis first

Judge international measures as effective at building consensus but limited by state sovereignty and weak enforcement; domestic measures give targets legal force but depend on political will.

Paragraph 1: The international framework

• The United Nations Framework Convention on Climate Change (1992) set up the process; the Kyoto Protocol (1997) set binding targets for developed countries only.
• The Paris Agreement (2015) aims to keep warming well below 2°C and to pursue efforts towards 1.5°C, with each state setting its own nationally determined contributions.
• Evaluation: near-universal participation is a success, but self-set targets and the lack of an enforcement mechanism reflect the barrier of state sovereignty.

Paragraph 2: Courts and advisory processes

• In 2025 the International Court of Justice delivered an advisory opinion on states' obligations in respect of climate change, requested by the UN General Assembly after a campaign led by Vanuatu.
• Evaluation: advisory opinions are not binding, but they clarify international law and can be relied on in domestic litigation and negotiations.

Paragraph 3: Australian domestic law

• The Climate Change Act 2022 (Cth) legislates a target of reducing emissions by $43\%$ below 2005 levels by 2030 and reaching net zero by 2050.
• In Minister for the Environment v Sharma [2022] FCAFC 35, the Full Federal Court overturned a finding that the Minister owed young people a duty of care when approving a coal mine extension.
• Evaluation: legislated targets give certainty, but the courts' reluctance to impose duties of care shows the limits of litigation as a climate response.

Paragraph 4: Non-government organisations

• NGOs and youth groups drive litigation, public pressure and scientific input into negotiations.
• Evaluation: they influence the agenda but have no power to enforce outcomes.

Final answer: Legal measures on climate change are only partially effective: the Paris Agreement, the 2025 ICJ advisory opinion and Australia's Climate Change Act 2022 (Cth) show growing legal commitment, but self-set targets, the non-binding nature of key outcomes and the limited role of courts mean implementation still depends on the political will of sovereign states.
