Defenses Flashcards
What is a credibility of evidence defense? Examples?
Fact-based defense focused on caling into question the credibility of the prosecution’s evidence.
Misidentification, witness lying/bias
What is a government misconduct defense? Examples?
Can be question of law or fact-based argument for jury focused on the legality or thoroughness of the investigation
Entrapment, prosecutorial misconduct, illegal search or seizure, forensic errors
What is a sufficiency of the evidence defense? Examples?
Question of law challenging that the government has not presented evidence to prove each element of the offense beyond a reasonable doubt
No proof of requisite mental state (mistake of law/fact), no proof of completed act
What is an affirmative defense? Examples?
A justification or excuse. Question of law not challenging that the elements ofthe offense have been met, but rather that a legal justification or excuse exists.
Self defense, duress/necessity, insanity, intoxication
How are affirmative defenses proven? Who bears the burden?
With affirmative defenses, the burden of proof shifts to the defendant, usually by a preponderance of the evidence, when the defense establishes separate and distinct facts in mitigation of culpability, as opposed to defenses that negate an element of the crime.
What are justifications?
Justifications focus on the act, not the actor, and excuse criminal conduct because it benefits society in some way or it is useful to society.
What are excuses?
Excuses focus on the actor, not the act, and excuse culpability because the actor is judged not to be blameworthy.
Is there a limit to what/how many defense theories are raised?
As long as there is sufficient evidence to support whatever defense theory they want to bring up, they can bring multiple defenses, even if the theories contradict. It is up to the jury to decide whether they buy any of the theories or not.
When must a judge instruct a jury about a defense? Why?
If a theory is sufficiently raised, the judge must instruct the jury on that defense. The Due Process clause guarantees a defendant’s right to present a defense.
When may/may not evidence of a defense theory be excluded?
When the exclusion of evidence significantly undermines fundamental elements of the defendant’s defense, it becomes unconstitutional. However, a trial court may exclude a defdendant’s evidence when their theory is unsupported, speculative, and far-fetched and could thereby confuse or mislead the jury.
Must the prosecution establish a defendant’s identity?
Yes. The prosecution must establish the defendant’s identity beyond a reasonable doubt as the perpetrator of the crime.
When does identity play a role in defense theories?
A common defense theory is that a third party actually committed the crime.
What evidence must a defendant provide to establish that a third person committed the crime?
Evidence that the third party had either motive or opportunity alone is too speculative. The defendant must have evidence that the third party had both motive and oppotunity.
What is often required for an alibi defense?
When the defendant proposes to offer evidence to the effect that he was at some other place at the time of the crime charged, he shall give notice in writing of that fact to the prosecution.
Regarding an alibi defense,
What does the notice usually state? Consequences of no notice?
The notice shall state where the defendant contends he was and names or witnesses to support the defense. Failure to provide the required notice bars the defendant from raising an alibi defense at trial.
Regarding the alibi defense,
Why is notice required?
Notice requirements are designed to eliminate the surprise alibi testimony at trial because the state cannot investigate alibi evidence until they know where and with whom the defendant claims to have been at the time of the crime.
Does the defendant have to provide notice if simply stating he wasn’t there?
No. Because the state knows it has to prove that the defendant was present at the scene fo the crime, so it should not be surprised by evidence that the defendant was merely not at the scene.
What is the necessity defense?
Necessity (choice of evils) is a defense when a person reasonably believes that the commission of a crime is necessary to avoid an imminent and greater injury to society than that involved in the crime. This is an objective test.
At common law, what was required of the injury in necessity?
At common law, the injury had to come from natural forces.
