Law is an area of study that covers a hugely diverse range of topics. The core subjects are grouped into three categories, although in practice these often intertwine and overlap. The first involves the nature and philosophy of law, with debates concerning the way a legal system ought to be created and operated. This is a highly complex subject that encompasses the concept of what constitutes justice and fairness as well as ideas about social change and the limits of power.
Another major topic concerns the legal process itself, from the way laws are drafted and voted on through to the ways that they are implemented. Laws are essentially rules or regulations that govern people’s interactions with one another. They can be made by private individuals or by government institutions. The underlying aim of a legal system is to protect individual rights and promote social stability. Some legal systems serve these goals more effectively than others. For example, an authoritarian regime may keep the peace and maintain the status quo, but it could oppress minorities or political opponents.
The third broad category of law is about legal practice, including civil and criminal proceedings, constitutional issues, judicial review, and the rules that must be followed by courts when trying cases. This includes the laws that govern a nation’s judicial system itself, and the rules about what evidence can be presented in court to support a case. This is a very complex field that covers a wide range of areas, from immigration law to family law and even a person’s right to be told what a jury has decided in a case.
A very important aspect of legal studies is the scholarly research that has taken place to explore the nature and philosophy of law. This is a vast field, which has included the work of philosophers, economists, sociologists and historians as well as lawyers. The key feature of this scholarly work is to try to understand how law is created and operated, with a view to making improvements to the efficiency and effectiveness of a legal system.
There is also a large body of academic writing that looks at the relationship between science and law, and how scientific principles can be applied to the creation of new legal rules. For example, it has been suggested that the idea of a hypothesis is a useful concept to apply to legal theory, with the law acting as a kind of hypothesis that is constantly evolving. This is a very challenging approach that has not always proved fruitful, however. The largely inflexible nature of the law means that there is still a strong sense of a gap between scientific ideals and the judicial reality. This is particularly clear in the way that the judicial community tends to ignore the advice of Holmes about objective probability assessment, and instead relies on faith, tradition, and the judgement of peers to interpret laws. This has led to a number of lively debates, for example about whether the judging class should be more diverse than it is.
