Evidence can be definedin four different ways:
The Lay Person’s Definition The Legal Definition The Technical Definition The Law Enforcement Officer’s
Definition
The Lay Person’sDefinition of Evidence
Evidence is information that people base decisions on and is used as the means by which those facts are proved or disproved.
The Legal Definition of Evidence
In a legal sense, evidence is any information about the facts of a case, including tangible items, testimony, and documents, photographs, or tapes, which, when presented to the jury at trial, tends to prove or disprove these facts.
The Technical Definitionof Evidence
Technically, evidence consists of: Testimony or physical items presented
to the judge and jury that they use to. decide the truth of an assertion, the existence of a fact, and. ultimately the guilt or innocence of
the accused in a criminal case.
The Law Enforcement Officer’s Definition or
View of Evidence. Evidence, to the
officer, is: Articles collected at
a crime scene; Items found on a
suspect, or in the suspect's car or home;
Things discovered during investigation.
Evidence of Proof Circumstantial
Inferences
Presumptions
Stipulations
Circumstantial Evidence Evidence which
proves a fact through inference, or logical association with other facts.
Inference Is the drawing of
a conclusion from an observation or series of observations
Presumptions A presumption permits the
fact-finder to conclude that, because a party has introduced evidence that one fact exists ["basic fact"], the jury may conclude that another fact ["presumed fact"] exists, even though the party has not introduced any other evidence of the existence of the presumed fact.
The Supreme Court’sTest for Presumptions
The Court has declared that, at a minimum, the presumed fact must flow from the basic fact measured by a standard of a preponderance of evidence.
Stipulations There are other facts that may be
presented during a trial without formal proof being required.
These are facts upon which the parties and their attorneys agree.
This agreement may take place either before or during the trial.
Once agreement has been reached, it will not be necessary to call witnesses to present the facts.
The Funnel Effect of the Standard of Proof
The Spectrum of the Standards of Proof. Can you
tell when each standard applies?
Preponderance of the evidence Mere hunch Reasonable suspicion Probable cause Clear and convincing evidence Absolute certainty Beyond a reasonable doubt
Arrange them in order.See next slide.
Burden of Proof
A Case Law Definitionof Reasonable Doubt
It is not a mere possible doubt; because everything relating to human affairs is open to some possible or imaginary doubt. It is that state of the case which, after the entire comparison and consideration of all the evidence, leaves the minds of the jurors in that condition that they cannot say they feel an abiding conviction of the truth of the charge.
