Probability in Legal reasoning: Its problems in the quest for Justice
Abstract
This is a multi-disciplinary research study. It focuses on the area of
philosophy of law. It attempts to examine the nature of probabilistic
reasoning and the inherent problems that it occasions in the course of the
quest for justice.
The upshot of research problem is on the inherent weakness of inductive
reasoning being apparently irrational as shown by David Hume. Induction, by
relying on past experiences to vindicate and strengthen its conclusions
proceeds by claiming that the past will be like the future. This claim, the
lifeline of inductive reasoning, is logically irrational. Yet, it is the refined
reformulations of inductive reasoning that are employed in legal reasoning
and on the basis of their conclusions, court verdicts are deliberated.
Therefore, the reasoning process, final court verdict and the consequent
total quest for justice by courts become suspect as they are enmeshed In
and embedded on the apparent irrationalism of induction.
The primary objective of this research study is to investigate and determine
the nature and extent to which probability in legal reasoning has occasioned
problems in the process of determination and dispensation of justice. The
research study has been guided by the principle of natural justice as its
theoretical framework. The research methodology utilized involves explication and critical
assessment of arguments, concepts and cognate issues and a detailed logical
analysis of various court rulings has been done to demonstrate how
intricately intertwined and crucial the concept of probability is in reaching
court verdicts and in the same strength show its pitfalls.
It is paramount to assess the relationship between causation, probability,
induction and justice. Therefore, in chapter two, a detailed study exposes
how deeply entrenched and inescapable cause-effect principle or causation,
inductive reasoning and probabilism are in legal reasoning and more so in the
process of fixation of legal responsibility. It has been argued how, why and
when the concept of probability is used specifically in demonstrating the
causal connection between agency and the harmful outcome.
A thematic continuation of chapter two, chapter three presents an
exposition of the logical structures-like the principle of evidence inquiry and
admissibility, standards of proof, presumption of innocence and probative
value and truth-that are employed to gauge and control the excesses of
probabilism in the process of legal reasoning.
However, in chapter four, it is argued that despite the existence and
application of these intellectual gauges and controls against probabilism,
glaring logical loopholes exist that renders the judicial reasoning unviable,
inaccurate, unfair and grossly unobjective in the course of determination and
dispensation of justice. These gauges or controls are flawed, entirely subjective and logically inconsistent in their application, hard to fulfill and
allows personal prejudice. This is how probability in legal reasoning
contributes to subjectivity in court deliberations and verdicts thus
compounding the quest for justice.
In the light of the above, it is ornply demonstrated how the concept of
probability in legal reasoning occasions problems in the quest for justice.
The concept of probability is not absolute and certain in relation to
circumstantial facts surrounding what really happened. The inconsistency
between certainty and the degree of proof accepted may mean punishing an
innocent person or escape from punishment of a guilty person. This is the
centrality of miscarriage of justice. In this way, probability has outlived its
usefulness and is highly recommended that inter alia, it should be replaced
with a more scientific method of reasoning. Principally, to achieve this, the
urgent appeal is to philosophers, first, to resolve the quagmire of
irrationalism of induction. The principle of natural justice greatly demands a
more compelling and intelligible method of reasoning.
