Comprehensive Guide to WJEC Criminology Unit 4

Getting Started with Law Making

This is your study guide for understanding how Parliament creates laws and how the criminal justice system operates in England and Wales. You'll learn about the step-by-step process that turns ideas into actual laws, plus how different agencies work together to catch and prosecute criminals.

These topics are essential for your criminology studies and will help you understand current events involving crime and legal changes. The processes might seem complicated at first, but once you break them down, they're quite logical!

💡 Quick Tip: Think of law-making like a quality control process - multiple stages ensure bad ideas get filtered out before becoming actual laws.

Understanding Parliament and Law Making

Parliament isn't just one building - it's made up of three crucial parts that all play a role in creating laws. The House of Commons contains elected MPs who represent different constituencies across the UK. The House of Lords includes both inherited peers and appointed life peers who review legislation. Finally, the monarch provides the symbolic seal of approval.

The law-making process starts with public consultation through a Green Paper, where the government asks for opinions on potential new laws. After considering feedback, they publish a White Paper with formal proposals, which becomes a Bill presented to Parliament.

Every Bill must pass through five stages in both houses: First Reading (introduction), Second Reading (main debate and vote), Committee Stage (detailed examination), Report Stage (feedback and amendments), and Third Reading (final vote). Only after Royal Assent does it become an Act of Parliament.

💡 Remember: Finance bills must always start in the House of Commons - this ensures elected representatives control how your taxes are spent.

How Judges Make Law Through Precedent

Think judges only apply existing laws? Think again! Judicial precedent means judges actually create law when they make decisions in court cases. Once a judge rules on a case, future courts must follow that decision in similar situations - this is called common law.

The famous Donoghue v Stevenson (1932) case perfectly illustrates this. When a woman found a decomposing snail in her ginger beer and fell ill, she sued the manufacturer. The court's decision created the 'neighbour principle' - the idea that companies owe a duty of care to their customers.

This precedent was later used in Daniels v White (1938) when someone found corrosive metal in their lemonade. Even though the facts were slightly different, the legal principle was similar enough to apply. This shows how one court case can shape the law for decades.

Senior courts like the Supreme Court can overturn previous decisions if they're outdated, but generally, precedents ensure the law remains consistent and predictable across the country.

💡 Study Hack: Learn these two cases well - they're classic examples of how judicial precedent works and often appear in exams.

Statutory Interpretation in Action

Sometimes judges must interpret what Acts of Parliament actually mean when the wording is unclear or outdated. This statutory interpretation can effectively create new law by clarifying how existing legislation should be applied.

Whiteley v Chappell (1868) shows how strictly judges can interpret legal wording. A man used a dead person's identity to vote illegally, but the court found him not guilty because the law said it was illegal to impersonate someone "entitled to vote" - and dead people can't vote!

Judges use different approaches like the literal rule (following exact wording), golden rule (avoiding absurd results), and mischief rule (considering Parliament's original intention). Their interpretations in higher courts like the Court of Appeal or Supreme Court become binding on lower courts.

This process shows how laws must adapt to new situations that Parliament couldn't have predicted when they wrote the original legislation.

💡 Exam Tip: The Whiteley case demonstrates the literal rule perfectly - remember how strict interpretation sometimes leads to unexpected results.

The Criminal Justice System Overview

The criminal justice system is like a well-oiled machine with different agencies handling specific roles from crime prevention to punishment. Understanding how these agencies connect will help you see the bigger picture of how justice actually works.

Law creation involves Parliament passing Acts and judges setting precedents through their court decisions. The Ministry of Justice and Home Office coordinate this entire system, ensuring everything runs smoothly from policy-making to implementation.

When crimes occur, law enforcement kicks into action with police responding first, securing crime scenes, and gathering evidence like fingerprints and DNA. Forensic experts then analyse this evidence using scientific techniques, providing crucial reports that can prove guilt or innocence.

The system culminates in courts where HM Courts and Tribunals Service manages proceedings, and finally punishment through HM Prison and Probation Service for convicted offenders.

💡 Key Insight: Each agency has a specific role, but they all depend on each other - the police need the CPS, courts need evidence, and prisons need court sentences.

How Law Enforcement Actually Works

Once a crime happens, the police spring into action as first responders, securing crime scenes and gathering initial evidence. Detectives take over investigations, interviewing witnesses and suspects while forensic teams collect DNA, fingerprints, and other scientific evidence.

Forensic experts are the scientific backbone of criminal investigations, using advanced techniques like DNA testing and toxicology to analyse evidence. They document everything meticulously and often testify in court, helping juries understand complex scientific findings.

After gathering sufficient evidence, police arrest suspects, but they can't just charge anyone they want. The Crown Prosecution Service (CPS) reviews all evidence and decides whether there's enough for a realistic chance of conviction. They work closely with police to ensure charges are appropriate and evidence is solid.

Defence lawyers enter the picture to represent accused persons, ensuring everyone gets a fair trial regardless of the charges. This balance between prosecution and defence is crucial for maintaining justice in the system.

💡 Real World: TV crime shows speed up this process dramatically - in reality, forensic analysis and CPS decisions can take weeks or months.

Courts and What Happens After Sentencing

HM Courts and Tribunals Service (HMCTS) manages two main types of criminal courts in England and Wales. Magistrates' courts handle less serious offences with unpaid, non-legally trained magistrates making decisions. Crown courts deal with serious crimes like murder and fraud, using professional judges and sometimes juries.

Once someone's convicted and sentenced to prison, prison officers take responsibility for their safe custody. These officers don't just lock people up - they maintain order, enforce rules, and importantly, help with rehabilitation by connecting prisoners to educational and vocational programmes.

Probation officers supervise offenders released from prison or given community sentences. They ensure people comply with conditions like attending rehabilitation programmes or staying away from certain areas. Their goal is reducing reoffending through support and monitoring.

Social workers provide additional support for offenders with mental health issues or substance abuse problems, working alongside probation officers to help people reintegrate into society successfully.

💡 Important: The system focuses heavily on rehabilitation, not just punishment - this approach aims to reduce future crime rates.

How All the Agencies Work Together

HM Prison and Probation Service currently supervises over 238,000 offenders across different programmes. They handle prisoners, people on community orders, and those under pre or post-release supervision, aiming to rehabilitate offenders for crime-free lives.

The connections between agencies are crucial for the system's effectiveness. Police work closely with the CPS, preparing case files and providing evidence for charging decisions. They also provide court security and help transfer convicted prisoners to appropriate facilities.

Courts depend on police evidence and CPS preparation to function properly. When they sentence someone to prison, they issue warrants authorising the prison service to take custody. The severity of crimes determines which type of prison facility offenders go to.

Voluntary organisations like Victim Support provide essential services that police refer victims to, offering counselling and legal advice throughout the justice process. When probation conditions are breached, probation services alert police who can re-arrest offenders.
