Law and Rules (OCR A-Level Law): Revision Notes
Law and Rules
What is law?
Law comprises rules, regulations and principles that are enforceable by the state. This distinguishes legal rules from other types of rules and social norms that govern our behaviour.
Legal rules have two essential characteristics:
- They are created by the state through various law-making bodies
- They are administered and enforced by state organisations, such as Her Majesty's Court Service, the police, and the court system
Compliance with legal rules is mandatory. We must obey laws regardless of our personal preferences, and failure to do so can result in state-imposed sanctions, such as fines, imprisonment, or other legal consequences.
The key distinguishing feature of legal rules is state enforcement. Without this element of state power to compel compliance and impose sanctions, a rule remains a social norm or voluntary guideline rather than a legal obligation.
Distinguishing legal rules from other rules and norms
Not all rules that govern human behaviour are legal rules. Many rules exist in society that we follow voluntarily rather than through legal compulsion.
Non-legal rules include:
- Rules of sports and games (such as the offside rule in football)
- Rules of social etiquette (such as table manners or queuing conventions)
- Professional codes of conduct
- Club or association rules
The crucial distinction is that non-legal rules are not enforceable by the state. We choose to follow these rules in particular contexts or situations. For example, if you break the rules of a board game, you cannot be prosecuted in a criminal court. The worst consequence might be exclusion from that game or club, but the state's legal machinery will not become involved.
In contrast, breaking a legal rule triggers the state's enforcement mechanisms. If you commit theft (breaking a legal rule), the police can investigate, prosecutors can bring charges, and courts can impose punishment.
Categories of legal rules and regulations
Legal rules can be divided into four main categories, each serving different functions within the legal system. Understanding these categories helps explain how law operates to regulate both state power and individual conduct.
Procedural laws
Procedural laws establish the framework and processes through which other laws are made, applied and enforced. They set out the "how" of the legal system rather than the "what."
Key functions:
- Define the steps that must be followed for laws to be validly created
- Prescribe how law enforcement agencies must act when exercising their powers
- Determine how legal proceedings are conducted in courts
- Establish who has access to legal assistance and under what conditions
Worked Example: The Police and Criminal Evidence Act 1984 (PACE)
PACE is a fundamental procedural law that sets out the procedure police officers must follow when making an arrest to ensure it is lawful.
How it works:
- Police must inform the person they are under arrest
- They must state the grounds for the arrest
- They must caution the person about their rights
- They must follow specific procedures for detention and questioning
Consequence of non-compliance: If police fail to follow PACE procedures, evidence may be excluded from trial, or the arrest itself may be unlawful.
Other procedural laws govern:
- How trials must be conducted
- Rules of evidence that determine what can be presented in court
- Who qualifies for legal aid and financial assistance when going to court
- Appeal procedures
- Time limits for bringing legal claims
Substantive laws
Substantive laws create, define and regulate legal rights and obligations. These are the laws that tell us what we can and cannot do, and what legal entitlements we have.
Key functions:
- Establish criminal offences and their penalties
- Create civil rights and duties
- Define the legal consequences of particular actions or omissions
- Set out the requirements for valid legal relationships (such as contracts or marriages)
Examples:
- Criminal offences are substantive laws: murder, theft, assault and fraud all define prohibited conduct and specify potential punishments
- Employment rights are substantive laws: they establish minimum wage entitlements, protection against unfair dismissal, and rights to parental leave
- The law of divorce is substantive: it sets out the grounds on which a marriage can be legally dissolved and the financial consequences
Substantive laws answer questions such as: "What conduct is criminal?" "What are my rights as an employee?" "How can I end my marriage legally?"
Substantive laws focus on the content and substance of legal rights and duties, while procedural laws focus on the processes for enforcing those rights. Both are essential for a functioning legal system.
Public laws
Public laws regulate the relationship between the state and its citizens. They define the powers of government institutions and establish limits on how the state can exercise authority over individuals.
Key functions:
- Define the powers and duties of Parliament, government ministers, and state agencies
- Establish the authority of institutions such as the police, courts and regulatory bodies
- Set constitutional principles that limit state power
- Create offences against the state or public order
Examples:
- Criminal laws are public laws because crimes are offences against the state, prosecuted by the Crown
- Most procedural laws are public laws, as they regulate how state institutions (such as courts and police) exercise their powers
- Constitutional law is public law: it defines the powers of Parliament, the government, and the relationship between different branches of the state
- Administrative law is public law: it regulates how government departments and public bodies make decisions and can be challenged through judicial review
Public law ensures that state power is exercised lawfully and that citizens have protections against arbitrary or unlawful state action.
A key feature of public law is that the state is always a party to the legal relationship or dispute. This distinguishes it from private law, where disputes occur between individuals or private organisations.
Private laws
Private laws create rights that are enforceable between individuals or private organisations. They regulate relationships between citizens rather than between citizens and the state.
Key characteristics:
- They are mainly substantive in nature, creating rights and duties
- They enable individuals to bring legal claims against one another
- The state provides the court system for resolving disputes, but the parties involved are private individuals or organisations
- Remedies typically involve compensation or orders requiring specific actions, rather than criminal punishment
Worked Example: The Law of Trespass
Trespass is a private law that allows you to restrict access to your property and take legal action against anyone who enters without permission.
How it works:
- You (the individual property owner) own the right to control access to your land
- If someone enters your property without permission, they commit a civil trespass
- You can bring a civil claim against the trespasser in court
- The state provides the court system, but you are the claimant, not the state
Outcome: The court may order the trespasser to pay you compensation or issue an injunction preventing future trespass.
Other examples of private law include:
- Contract law: governs agreements between parties
- Tort law: provides remedies when one person wrongfully causes harm to another
- Family law (in its private aspects): regulates relationships such as marriage and disputes over children
- Property law: establishes ownership rights and how property can be transferred
Exam guidance
When answering questions about law and rules, ensure you:
- Clearly distinguish between legal rules (enforceable by the state) and other social rules (voluntary compliance)
- Use specific examples to illustrate each category of law, such as PACE 1984 for procedural law or trespass for private law
- Explain the purpose of each category, not just define it
- Demonstrate understanding that some laws can fall into multiple categories (for example, criminal law is both public and substantive)
- Make connections between this topic and other areas of the legal system you have studied, such as how courts enforce laws or how Parliament creates substantive legislation
Exam Tip: When discussing categories of law, always explain why a law belongs to a particular category by reference to its purpose and function, not just stating what category it falls into.
Key Points to Remember:
-
Law consists of rules, regulations and principles enforceable by the state – this is what makes legal rules different from other social norms
-
Legal compliance is mandatory, whereas other rules (sports, etiquette) are followed by choice in particular situations
-
Procedural laws establish the framework for making and enforcing other laws (e.g., PACE 1984 governs police arrest procedures)
-
Substantive laws create and define legal rights and obligations (e.g., criminal offences, employment rights, divorce law)
-
Public laws govern the relationship between the state and citizens (e.g., criminal law, constitutional law) and define state powers
-
Private laws create rights enforceable between individuals, mainly substantive in nature (e.g., trespass, contract, tort)
-
Key distinction: Public law involves the state as a party; private law involves disputes between individuals or organisations, with the state providing only the court framework
