Case Law
Advantages of case law
1) Certainty
2) Detailed practical rules
3) Free market in legal ideas
4) Flexibility
➔Certainty
Judicial precedent means litigants can assume that like cases will be treated alike, rather than
judges making their own random decisions, which nobody could predict. This helps people to
plan their affairs.
➔Detailed practical rules
Case law is a response to real situations, as opposed to statutes, which may be more heavily
based on theory and logic. Case law shows the detailed application of the law to various
circumstances, and thus gives more information than statute. The academic Roscoe Pound
(1963) has written on the doctrine of precedent:
- Growth is ensured in that the limits of the principle are not fixed authoritatively once
and for all but are discovered gradually by a process of inclusion and exclusion as cases
arise which bring out its practical workings and prove how far it may be made to do
justice in its actual operation.
➔Free market in legal ideas
The right-wing philosopher Hayek (1982) has argued that there should be as little legislation as
possible, with case law becoming the main source of law. He sees case law as developing in line
with market forces: if the ratio of a case is seen not to work, it will be abandoned; if it works, it
will be followed. In this way the law can develop in response to demand. Hayek sees statute law
as imposed by social planners, forcing their views on society whether the majority of people like
it or not, and threatening the liberty of the individual.
➔Flexibility
Law needs to be flexible to meet the needs of a changing society, and case law can make changes
far more quickly than Parliament. The most obvious signs of this are the radical changes the
House of Lords made in the field of criminal law, following announcing in 1966 that its judges
would no longer be bound by their own decisions.
Disadvantages of case law
1) Complexity and volume
2) Rigid
3) Illogical distinctions
4) Unpredictable
5) Unsystematic progression
6) Dependence on chance
7) Lack of research
8) Retrospective effect
KEY CASE
Case: SW v United Kingdom (1995)
Facts: Two men, who had been convicted of the rape and attempted rape of their wives,
