Introduction
The statement that the role of private law is to uphold rights and to enforce duties provides a foundational understanding of the relationship between individuals, and between individuals and corporations, in a legal system. Private law, encompassing areas such as contract, tort, and property, governs the horizontal relationships between legal persons. This essay will argue that while the upholding of rights and the corresponding enforcement of duties is indeed a central function of private law, this is not its only role. A complete view must also recognise that private law serves to facilitate transactions, provide mechanisms for compensation, and allocate risk. Therefore, the statement is a valid but incomplete description of the function of private law in England and Wales.
The Core Function: Rights and Duties
At its core, private law operates on the principle of correlativity, where one person’s right corresponds to another person’s duty. This framework is most visible in the law of obligations, which consists of contract and tort.
In contract law, parties voluntarily create their own rights and duties. When a legally binding agreement is formed, each party acquires a right to performance from the other, who in turn owes a duty to perform their part of the bargain. For example, under the Sale of Goods Act 1979, a seller has a duty to provide goods of satisfactory quality, and the buyer has a right to receive such goods (s.14(2)). If the seller breaches this duty, the law provides the buyer with a remedy, thereby enforcing the buyer's right. The classic case of Carlill v Carbolic Smoke Ball Co [1893] 1 QB 256 illustrates this. The company’s advertisement created a duty to pay £100 to anyone who fulfilled the conditions, giving Mrs Carlill a corresponding right to claim the money once she had done so. The court's decision enforced this duty and upheld her right.
Similarly, the law of tort protects pre-existing rights, such as the right to bodily integrity or to one’s reputation, by imposing duties on others not to infringe upon them. The tort of negligence is a prime example. The landmark case of Donoghue v Stevenson [1932] AC 562 established the ‘neighbour principle’, which created a general duty of care owed to those who could be foreseeably affected by one's actions. A claimant who is injured due to a breach of this duty has a right to be compensated for their loss, which the court enforces by ordering the defendant to pay damages. This demonstrates the law acting to uphold the claimant’s right to be safe from another's carelessness and enforcing the defendant’s duty to be careful. This perspective aligns with a corrective justice theory, where the law's role is to correct the imbalance created when a defendant wrongfully interferes with a claimant's rights (Cane, 2007).
Beyond Rights and Duties
While the rights-and-duties model is a powerful explanatory tool, it does not capture the full scope of private law's function. Private law also has important facilitative and compensatory roles.
Firstly, contract law is not merely about enforcing duties; it is a facilitative framework that enables commerce and social co-operation. It provides a set of default rules and a structure which parties can use to plan their affairs and allocate risks as they see fit (McKendrick, 2021). The law empowers individuals and businesses to create their own private legal arrangements, with the courts acting as a backstop if something goes wrong. In this sense, its primary function is arguably more about providing the tools for economic activity than simply enforcing duties after a breach.
Secondly, in tort law, while the language of rights is used, the system's practical operation often appears more focused on compensation and loss distribution (Horsey and Rackley, 2021). The existence of compulsory liability insurance, for instance in relation to road traffic accidents, means that the duty to pay damages rarely falls on the individual tortfeasor. Instead, losses are distributed amongst a wider pool of premium-paying motorists. This suggests a function that is less about enforcing an individual duty and more about achieving a socially acceptable allocation of the costs of accidents.
Conclusion
In conclusion, the statement that private law's role is to uphold rights and enforce duties is largely accurate and serves as a crucial starting point for understanding its purpose. The structure of contract and tort is built upon the correlative nature of rights and duties, and judicial remedies are designed to give effect to them. However, this view is a simplification. Private law also performs other vital functions, such as facilitating economic transactions and distributing loss, which are not fully captured by the rights-and-duties model. Therefore, while upholding rights and enforcing duties is arguably the primary role of private law, it is not its exclusive one. A broader perspective reveals a more complex system that is also facilitative and compensatory in nature.
