Sound Legal Reasoning
Sound Legal Reasoning:
• Recognize a sound well supported legal argument
• Sound legal reasoning harmonizes four important
considerations in legal decision making
○ What the judges decide, building blocks present
in every case.
The Four Elements of Legal Reasoning:
1. Case Facts
○ Established in the trial and preserved in the
record of the evidence produced at trial
§ Facts about the dispute between the
parties in the case as developed during a
trial.
○ Case facts can be proven by reference to the
physical world
§ Has to be proof - the quality of proof,
reliability of proof
□ Is the image accurate? Is a document
authentic? Is a witness identification
reliable?
2. Social Background Facts
○ The facts, events, and other conditions that we
observe In the world, apart from the case at hand
§ Proven by reference to the outside world
○ Conclusions about the world independent of the
specific case facts that the parties are disputing
§ Can include anything about how the world
works
□ Often times is so obvious there is no
argument
○ When the social background facts in a case are
not so clear, judges and juries will rely on
hunches about them
3. Rules of Law ○ When the social background facts in a case are
not so clear, judges and juries will rely on
hunches about them
3. Rules of Law
○ Official legal texts created by the state
○ Rule of law relevant to a case
§ Statutes
§ Constitutions
§ Precedents - previously decided cases
4. Widely Shared Values
○ Judges must take account of social values to be
convincing
§ Not own values, or values they think are
most worthy
§ Judges must try to persuade communities
that they have considered the widely
shared values that ordinary members of
the community can see embedded in the
dispute.
○ Supreme Courts highest function may be to help
society resolve the conflict between the good and
the good
§ Legal rules don't tell judges which good to
choose
○ Even when values and principles are shared there
is still disagreements a to which are relevant to a
given dispute or which take precedence.
§ No single opinion will persuade everyone
§ Values and principles cannot be proven or
objectively ranked
○ How do you make a compelling and sound legal
argument?
§ Aim for internal coherence, and clear
explication
§ Don't ask the judge, jury, parties or public
to trust you - show them how the position
you advocate for accounts for the relevant
facts, law and policy
○ Think like a lawyer
§ Like a roadmap - XYZ - avoid pitfalls
□ Weather, road construction - social
background facts you advocate for accounts for the relevant
facts, law and policy
○ Think like a lawyer
§ Like a roadmap - XYZ - avoid pitfalls
□ Weather, road construction - social
background facts
□ Speed limits - law
□ Mileage, carbon emissions, scenery widely held values and principles
□ Type of vehicle and cost of tolls facts
§ When you harmonize all considerations this
is where you ought to end up
○ Effective and sound legal reasoning guides the
audience to the desired outcomes, to appear
logical, unavoidable, legitimate, and defensible.
○ inspires confidence in the legal system because it
provides explanation and justification.
