The primary focus areas include relevance, witnesses, hearsay, authentication, the best evidence rule, privileges, and policy-based exclusions. **Relevance** Definition: Evidence is relevant if it has any tendency to make a material fact more probable or less probable than it would be without the evidence. All irrelevant evidence is inadmissible unless excluded by specific rules or outweighed by pragmatic considerations. Balancing Factors: The danger of unfair prejudice, confusion of issues, misleading the jury, undue delay, waste of time, and cumulative evidence are considered when evaluating the probative value. Similar Occurrences: Evidence concerning events other than those involved in the case at hand is generally inadmissible due to weak relevance and pragmatic concerns. However, exceptions exist for plaintiffs' accident history, similar accidents caused by the same instrumentality, intent issues, comparable sales, and habit evidence. **Policy-Based Exclusions** Liability Insurance: Evidence of liability insurance is inadmissible for proving fault or absence of fault but may be used for other purposes like ownership or control. Subsequent Remedial Measures: Post-accident repairs are inadmissible for proving negligence or product defect but may be used for showing ownership/control or feasibility of safer conditions if disputed. Settlements: Offers to settle or facts stated during settlement discussions are inadmissible for proving liability but may be used for impeaching bias or in criminal cases involving government agencies. **Character Evidence** General Rule: Character evidence is inadmissible to prove conduct on a particular occasion except when character is an essential element of the claim or defense. In criminal cases, defendants may introduce evidence of pertinent good character traits, opening the door for prosecution rebuttal. Victims' Character: In self-defense cases, defendants may introduce evidence of victims' violent character as circumstantial evidence that the victim was the first aggressor. In sexual misconduct cases, rape shield laws limit admissibility of victims' sexual behavior unless specific exceptions apply. **Authentication of Writings** Methods: Witness personal knowledge, proof of handwriting (lay opinion, expert comparison, jury comparison), circumstantial evidence, ancient document rule, solicited reply doctrine, and self-authenticating documents. **Best Evidence Rule** Definition: To prove the content of a writing, the original must be produced unless an acceptable excuse exists. Secondary evidence can then be used if the court accepts the excuse. Exceptions: Applies when writings create rights/obligations or when witness testimony is based solely on written records. **Witnesses** Competency: Witnesses must have personal knowledge and take an oath or affirmation. Dead man statutes may render interested witnesses incompetent in civil actions against decedents' estates. Leading Questions: Generally disallowed on direct examination but permitted on cross-examination and in specific situations like preliminary matters or hostile witnesses. Refreshing Recollection and Past Recollection Recorded: Witnesses may use memoranda to refresh recollection, but these cannot be introduced as exhibits. If memory fails, past recollection recorded serves as an exception to hearsay. Opinion Testimony: Lay opinions must be rationally based on perception and helpful to the jury. Expert opinions require qualifications, proper subject matter, and reasonable bases including permissible data sources. **Credibility and Impeachment** Bolstering: Not allowed until after a witness's credibility has been attacked. Rehabilitation methods include prior consistent statements, reputation/opinion for truthfulness, and learned treatises. Impeachment Methods: Prior inconsistent statements, bias, sensory deficiencies, bad reputation/opinion about truthfulness, criminal convictions, bad acts reflecting on truthfulness, and contradictions. Extrinsic evidence is limited to non-collateral matters. **Privileges** Attorney-Client Privilege: Protects confidential communications made during professional consultations unless waived or exceptions apply. Physician-Patient Privilege: Covers confidential communications for diagnosis/treatment; psychotherapist privilege exists in federal courts for mental/emotional conditions. Spousal Privileges: Spousal immunity prevents spouse from testifying adversely in criminal cases. Confidential communications between spouses are privileged in all types of cases with specific exceptions. **Hearsay** Definition: An out-of-court statement offered to prove the truth of the matter asserted. Hearsay is inadmissible unless an exception applies. Non-Hearsay Purposes: Verbal acts, effect on listeners, circumstantial evidence of state of mind, statements of trial witnesses, and party admissions. Exceptions: * Former Testimony: Admissible if given under oath and opportunity for cross-examination existed previously. * Statement Against Interest: Unavailable declarant's statement damaging to their pecuniary, proprietary, or penal interests. * Dying Declaration: Statement concerning cause/circumstances of impending death in homicide prosecutions or any civil case. * Excited Utterance: Statement concerning startling event made while under stress of excitement. * Present Sense Impression: Description of event made while occurring or immediately thereafter. * State of Mind: Declarations reflecting current feelings/emotions. * Intent: Declarations of intent to do something in the future. * Present Physical Condition: Statements about current physical condition. * Medical Diagnosis/Treatment: Statements made for obtaining medical treatment/diagnosis. * Business Records: Regularly kept records made contemporaneously by employees or falling within independent hearsay exceptions. * Public Records: Records setting forth activities of public offices/agencies or findings from authorized investigations. Confrontation Clause: In criminal cases, testimonial hearsay is inadmissible unless defendant had opportunity for cross-examination. Forfeiture by Wrongdoing: Hearsay is admissible if defendant's wrongdoing made the witness unavailable.
