The Criminal Justice System
Crime: Investigation Process and Bail
-
The criminal justice system defines offences, investigates wrongdoing, determines guilt through fair and transparent processes, and imposes proportionate punishment according to law. Each stage, from investigation and arrest, to bail, trial, sentencing, and punishment, must operate lawfully, protect individual rights, and uphold the rule of law by ensuring that state power is exercised fairly, consistently, and with proper safeguards.
-
This explainer examines recent debates over Queensland’s bail laws, showing how media‑driven public pressure and concerns about youth crime have prompted proposals that weaken the presumption of innocence and shift the burden of proof onto accused young people. It highlights why reactive reforms risk undermining core rule of law principles and argues for evidence‑based, proportionate responses that target recidivism without eroding fundamental legal protections.
-
This explainer outlines how police investigate crime using powers such as search, seizure, arrest, and warrants, while emphasising the legal checks, like reasonable suspicion, oversight bodies, and admissibility rules, that prevent misuse of authority and protect individual rights.
-
This explainer outlines how bail protects the presumption of innocence while managing risks to community safety. It explains the purpose of bail, the factors police and courts must consider and how rule‑of‑law principles ensure decisions are fair, transparent and based on evidence rather than public pressure.

This explainer clarifies the difference between summary and indictable offences and how each type moves through the criminal justice system. It outlines which matters are heard in the Local Court, which proceed to higher courts and how the classification of an offence affects procedure, rights and sentencing.
Crime: Criminal Trial Process
-
This explainer outlines how the adversary system structures criminal trials by giving both the prosecution and defence an equal opportunity to present their case before an impartial judge or jury. It highlights how fairness, equality of representation, and judicial impartiality underpin the system, while also noting concerns about resource imbalances and the importance of procedural justice in upholding the rule of law.
-
This explainer outlines the main participants in a criminal courtroom and explains how each contributes to a fair and lawful trial. It highlights how impartial judging, the separation of powers, the burden and standard of proof, and the rights of the accused work together to ensure justice is done and seen to be done.
-
This explainer outlines how criminal charges are laid and how an accused person may plead guilty or not guilty, shaping whether a matter proceeds to sentencing or to a full trial. It highlights the differences between summary and indictable offences, the role of plea bargaining, and how early guilty pleas can reduce sentences, while not‑guilty pleas require the prosecution to prove the case in court.
-
This explainer outlines the prosecution’s duty to prove an accused person’s guilt and explains why juries may only convict if satisfied beyond reasonable doubt. It highlights how this high standard protects the presumption of innocence, prevents wrongful convictions, and ensures that criminal justice operates fairly, transparently, and in line with core rule‑of‑law principles.
-
This explainer outlines how evidence is gathered, assessed, and admitted in criminal trials, showing how strict rules ensure only reliable, relevant, and lawfully obtained material is considered by the court. It highlights the different types of evidence, the role of police and prosecutors in preparing a brief of evidence, and how judges and juries evaluate admissibility and weight to protect fairness, prevent wrongful convictions, and uphold due process.
-
This explainer outlines the major legal defences an accused person may rely on to avoid or reduce criminal liability, including duress, consent, self‑defence, mental illness, and intoxication. It highlights the strict evidentiary requirements for each defence and shows how they operate to ensure that only morally and legally blameworthy conduct results in conviction, reinforcing fairness and due process in the criminal justice system.
-
This explainer outlines the role of juries as impartial fact‑finders who decide guilt or innocence based solely on the evidence presented in court. It highlights how jury service promotes democratic participation, safeguards against arbitrary state power, and ensures that criminal justice outcomes reflect community values, while also acknowledging challenges such as juror bias, media influence, and the complexity of modern trials.
-
This explainer outlines the criminal standard of proof and why prosecutors must prove guilt beyond reasonable doubt. It explains how the standard protects the presumption of innocence, what “reasonable doubt” means in practice and how judges direct juries to apply it. The resource highlights the importance of high proof standards in safeguarding fairness and preventing wrongful convictions.
Crime: Sentencing and Punishment
-
This explainer outlines how post‑sentence regimes—such as Continuing Detention Orders and Extended Supervision Orders—allow high‑risk offenders to be detained or strictly monitored after completing their custodial sentences. It highlights the significant rule‑of‑law concerns these regimes raise, including retrospective punishment, limits on liberty, the blending of civil and criminal standards, and the challenge of balancing community protection with the rights of offenders, victims, and society.
-
This explainer outlines significant reforms to NSW sentencing law, including the replacement of bonds and suspended sentences with new community‑based orders (Conditional Release Orders, Community Correction Orders, and strengthened Intensive Correction Orders). It highlights how these changes aim to improve community safety, streamline guilty‑plea processes, and modernise sentencing options while preserving judicial discretion and ensuring proportionate, evidence‑based penalties.
-
Outlines how sentencing depends on judicial independence and careful consideration of the unique facts of each case. Using R v Dowdle, it illustrates why rigid mandatory sentencing rules can produce unjust outcomes and why judges must retain discretion to balance punishment, deterrence, rehabilitation, and the offender’s circumstances.
-
This resource explains how mandatory sentencing limits judicial discretion, shifts power to prosecutors, and risks disproportionate punishment. It outlines key rule of law concerns, including separation of powers, reduced fairness, and higher prison populations, while contrasting mandatory minimums with established sentencing purposes and principles that ensure proportional, evidence‑based outcomes.
Judicial Independence in Sentencing
Sentencing decisions of judges are often commented on by the media. In particular, judges are often criticised for being too lenient on offenders. Judicial independence is a fundamental principle of the rule of law and requires that judges make decisions based on the facts of the case and relevant legislation and that these decision are then written down and published to demonstrate the judge’s reasoning.
The case summary below demonstrates that each case that comes before a judge has a set of specific facts that ought to be taken into account in sentencing. Broad rules about mandatory and minimum sentencing may not take into account the human element and allow judges to make decisions that may best reflect community concerns, rehabilitation and the burden (both monetary and social) of prescribed sentences.
R v Susan Dowdle [2018] NSWSC 240
A recent decision of His Honour Justice Hamill in the Supreme Court of New South Wales, demonstrates the complex issues that the court has to consider when sentencing an offender. His Honour’s decision in R v Susan Dowdle [2018] NSWSC 240 provides a very good summary of the legal issues the court has to take into account and how that fits with the circumstances of the case and the history of the offender.
When sentencing an offender, His Honour started the judgment with the following statements:
This is an intensely sad case … It involves the mercy killing of a son by his mother [1-2]
He outlined how the court has to consider the factors of punishment, deterrence, protection of the community and rehabilitation when going through the process of sentencing a person.
In regard to punishment, His Honour said that the crime of manslaughter is one of the most serious crimes.
The law needs to be seen to protect the sanctity of human life and the maximum penalty of 25 years for this offence must therefore be taken into account in sentencing.
The sentence must send a message to the community that there is no justification for taking a human life. The offender, Ms Dowdle, had entered a plea of guilty to the manslaughter of her son, then aged 26 and for whom she was the main caregiver.
The offender’s son had suffered a serious brain injury in a motor vehicle accident in 2008. As a result of that injury he became an alcoholic and took drugs.
His personality changed and his behaviour placed a significant burden on his mother. Evidence at the sentencing hearing indicated that he had frequent altercations with neighbours and the police.
The police were usually called twice a week and he was frequently hospitalised due to his substance abuse issues. Further evidence indicated that he was violent towards his mother, would try and choke her, and that she had bruises and other injuries, including cigarette burns on her body.
Ms Dowdle had sought the assistance of drug and alcohol services, counsellors, psychiatrists and psychologists in an attempt to help her son. She tried to arrange for him to enter drug and alcohol programmes and mental health facilities, but, from the evidence provided to the court, it appears that she dealt with her son’s issues on her own.
On the day of the offence Ms Dowdle gave her son an overdose of sedatives, which had been prescribed by a doctor and then asphyxiated him with a plastic bag. She told police that she had wanted to end his pain.
She had her own difficult life history.
There was evidence that she had been assaulted as a child and that she had suffered from a significant psychiatric illness in her late teenage years, which required hospitalisation and electroconvulsive therapy. She had married and had two sons. The evidence was that by 2016 Ms Dowdle was medically depressed, due to her pre-existing mental health issues and the exhaustion of caring for her son.
At the time of sentencing Ms Dowdle had spent two years in gaol. She had a minimal criminal record, one offence of mid-range drink driving, and there was nothing in her pre-sentence report that suggested she would offend again.
The judge found that she has an excellent chance of rehabilitation and was of good character and she had demonstrated significant remorse. Substantial impairment was argued as part of the offender’s plea, on the basis that she was so impaired by a psychiatric disorder that the charge should be reduced from murder to manslaughter. That plea was accepted by the prosecution and ultimately the court.
His Honour noted, however, that the victim was vulnerable, due to his disability and intoxication, that the offence took place in his own home, where he should have felt safe and that the offender was the victim’s mother and guardian and was therefore morally obliged to protect him.
In all of the circumstances the court found that the only appropriate sentence was a custodial one. Ms Dowdle was sentenced to a three year custodial sentence, with a non-parole period of two years. As she had already served two years in custody, she was released into the community and was to be on parole for a further year.
In his judgment, His Honour reflected on the particular facts of this case and the loss of the person that resulted in these proceedings.
I suspect the person who grieves Digby the most is in fact sitting before me in the dock.[36]
