EVIDENCE – Exam Guide
BASIC STEPS:
1)Admissible?
- PV v. PE
- Specific to case/evidence in question
- Mention PV v. PE in general Overarching Policy considerations, Qualified search for Truth
- Other specific TESTS for each type of evidence
- Presumptions / Onus / Standard of Proof
- Who is submitting – Crown or Defense (corresponding duties/leeway)
- Civil or Criminal context
- IF WITNESS – competent and compellable?
2)For What Purpose? (the specific Issue, what is actually Disputed)
- Truth
- Credibility
- Identity
- Level of culpability (or proof of functioning / cognitive mind?)
- State of mind
- Collusion
3)Limiting Instructions?
- WEIGHT?
- Editing
- Who decides – judge or jury
PROBATIVE VALUE v. PREJUDICIAL EFFECT
-WEIGHING PV (search for Truth) with PE (justice, fairness, policies)
Probative Value: must be both relevant AND material
-1) Relevance
- Increase/decrease probability of existence of a FACT in issue
- Relationship b/w evidence and
-2) Materiality
- Relationship b/w evidence and the MATTERS in Issue
-No minimum PV required
-In issue: look at framework of case, elements of offence
-Proximity in time and space to offence
-Degree of nexus b/w evidence and event in question
Prejudicial Effect:
-1) Prejudice to immediate Accused
-Potential to cause jury to prejudge, jump to conclusions
- arouse emotions of prejudice, sympathy, hostility, stereotypes
- distraction
- danger of punishing Accused for other misconduct
- time-wasting
- unfair surprise
-2) Prejudice to Admin of Justice
-negative effects, cause disrepute – broader notions of equity, confidence in system…
-**Limiting Instructions can diminish PE
BALANCE – Overarching Policy Considerations
-Relative Degrees of PV and PE…(and depends on which side is leading…)
- **Higher bar for excluding Defense evidence…Seaboyer, PE must substantially outweigh PV in order to exclude as inadmissible
-Err on side of Admissible (weight, instructions) but must be Credible / Reliable if Crown leads
-Exclude evidence that could lead to wrongful conviction - important link to show in EXAM
-**RARD need not be based on proven factsW(D):
- If believe accused; acquit
- If do not believe accused, but evidence RARD; acquit
- If do not know who to believe; acquit
WEIGHT / LIMITING INSTRUCTIONS:
-Tell WHY evidence is being admitted:
- Limit what can be used for -If evidence can have good probative value for one purpose, but can be misused for other purposes…
- Weight it should be given
-***ALWAYS remind Jury, warn against using it for prejudicial reasons, link to wrongful convictions
TYPES of EVIDENCE
-Everything admissible is led before Jury, they find FACTS from it
- Presumption: need evidence to prove any inferences to be drawn/facts to be proven
-Once Admissible Jury examines evidence as a whole - do not have to assess BARD each piece of evidence first, before using to consider facts/verdict
- Accused does not have to prove facts to have an inference drawn
- Crown evidence has to be Credible and Reliable
Direct OR Circumstantial
Direct: Evidence that can be used w/o drawing any further inference, evidence speaks for itself
- Ex. Eyewitness evidence
- 2 Possibilities of Error: mistake of witness, person is lying
- EYEWITNESS Identification: presumption - ADMISSIBLE
- but dangerous from Reliability standpoint
- more reliable if W knows Accused, view, proximity, time
- stressful situation, or Transference (seeing Accused, photo line up, media)
- Instructions to Jury:
- May (not required) look for Corroborating Evidence
- Clearly set out risk of mistake, link to wrongful convictions
- If potential tainting, give it very little weight
Circumstantial: Need to draw an inference from it to use it
- 3 Possibilities of Error: above 2, plus Improper Inference
-Myth: that you cannot convict on circumstantial evidence, can often be incredibly strong, stronger than direct
-Miller error: circumstantial evidence from which Crown would ask jury to draw inferences MUST be proven facts…but proven facts instruction does not apply to D (doesn’t need to prove anything, just RARD)
REAL / DEMONSTRATIVE
-gives trier of fact complete first hand impression, can be directly inspected, flows directly from crime (ex. Gun, video, photos) OBJECTS – not witnesses??
-Direct Evidence: to some extent evidence speaks for itself, but need to consider procedures
-Admissibility/Weight: DEPENDS:
- If problems not so bad, is a weight issue,
- but if lots of problems – admissibility issue
- If legitimate purpose for putting in, Court unlikely to prohibit, but likely to edit, make sure not used for improper purpose Limiting Instructions
-Onus: on person leading, to provide evidence of Authenticity
Specific TESTS:
-Videos/Photos
- 1) Authentication
- Verification on oath by person capable to do so
- Person who made video: how evidence came into existence
- Witness: confirm it is an accurate description
- Technician: set up camera, process of the camera
- 2) Misleading?
- Fairness, absence of intention to mislead
- Basic PV v. PE: For what Purpose being led?Affects the Balance…
- Establish accuracy in truly representing facts
- Intermittent gaps
- Selective editing – motive (Penny)
- Format Changing
- 3) Even if above 2 met, Can still Prejudice - if Highly Inflammatory (esp. for Photos)
- Demonstrate that which something less graphic could not show
- Judge may limit the amount of photos shown…or specific ones
-Documents
- 1) Authentication:
- When, where, how created, basic history
- Person who authored testifies
- Someone who was present (ex. Board meeting) vouches for accuracy
- Found in possession of A or witness (helpful depending on purpose)
- 2) Best Evidence Rule:
- Have Original – use it
- Copy – authenticate it
- Manner of Destruction of original – accidental (OK), intentional (problems for admissibility)
- Bank records: 1) any form 2) may change 3) may be complation or collation of other records 4) must been produced as reference source, or part of internal audit system
Judicial Notice
-Circumstantial –
-Presumption: need evidence to prove any inferences to be drawn/facts to be proven
- Facts that are either so notorious or generally accepted as to not be subject of debate among reasonable persons
- High standard
- NOT: money for training child to be pro athlete, or lawyers will not take cases if have to pay costs out of own pocket
FOCUS
If trying to include – in principle:
-proper authenticating evidence provided
-highly probative,
-edit amount of photos shown, OK
- Possible examples from caselaw
- Bank records
If trying to exclude – in principle:
-selective editing – motives
-destruction of docs for sinister reason
-overall – Inflammatory, prejudicial
- Possible examples from caselaw
- Transcripts
- Video with selective editing, going to method not identity
EXTRINSIC MISCONDUCT
-Circumstantial - Misconduct of Accused or a party/witness that is outside the subject matter of the proceeding
-Type of evidence that can lead to serious miscarriages of justice
-Potential for Prejudice:
- Propensity reasoning/evidence – BAD – should be excluded
- Punish for previous acts
- Distraction
- May lower standard of proof
-CIVIL Cases: more flexibility, not as concerned about prejudice, but still use Crim standards
(Extrinsic Misconduct) – BAD CHARACTER of the ACCUSED
-Presumption: INADMISSIBLE – Accused character is not in issue
- Strict test: General Propensity is not enough, PE outweighs PV
- Exception: Specific Propensity – Similar Fact Evidence
- GOOD CHARACTER?
- Goes to weight, but opens the door for Crown to address Bad Character
-Onus: on the Crown
- SoP: BOP - in the circumstances of particular case the PV outweighs the PE
General TEST for ADMISSIBILITY:
- 1) Relevant to a material issue beyond Bad Character?
- Ex. Credibility?
- AND
- 2) Does PV outweigh the PE?
- Judge can allow some of the BC evidence in
- ***Limiting Instructions: Even if admissible, Judge needs to warn jury about what evidence can and cannot be used for
EXCEPTION: SIMILAR FACT EVIDENCE
-Presumption: INADMISSIBLE (Character Evidence)
-Onus: on the Crown
- SoP: BOP - in the circumstances of particular case the PV outweighs the PE
- And, identify the issue to which SFE relates
-MUST be accompanied by Limiting Instructions – if Admissible, still Weight issues
- How to use evidence, which issue it bears on
- **Cannot use SFE to make inference that Accused is of a character to do this crime
-PV - Based on level of similarities ***objective improbability of coincidence ***
-Often can make or break your case – once jury sees evidence of pattern of conduct, more likely to convict
-Can use Incident 1 to determine guilt on Incident 2
Basic Admissibility TEST PV v. PE
- distinct and particular propensity to act in a specific way under specific circumstances
- FACTORS:
- Proximity in time
- Similar in detail (conduct itself, hallmarks)
- Number of similar acts
- Circumstances and context around the acts (sports-bar fight-weapon)
- Strength of reliability of SFE
- Amount of time to adduce the SFE
- 1) Weight of PV
- Strength of evidence that similar acts actually occurred (collusion/collaboration?)
- Connectedness – extent to which proposed evidence aids the inferences made
- Materiality of the matters it is intending to prove
- 2) Potential for Prejdice (moral, and reasoning)
- 3) BALANCE
Identity TEST:
- 1) Such high degree of similarity, objectively improbable that crimes committed by more than one person
- 2) Is there some evidence linkingAccused to the similar acts?
Collusion TEST:
- Chance that similar accusations against A could be produce of Collusion weight
- Air of Realityto the accusation of collusion admissibility
- Crown must show on BOP “NO Collusion”

(Extrinsic Misconduct) – POST OFFENCE CONDUCT
-Circumstantial – based on conduct of the Accused after the offense, leads to guilty inference
-Presumption: ADMISSIBLE – leave to Jury to decide why they are acting that way, weight
-Onus:
- SofP: if central issue to Crown case, basically for jurors to consider BARD
Admissibility TEST:
- If at least one reasonable explanation that Accused was guilty, leave to Jury**
- If certain DEFENSES are put forward
- Self Defense: assertion of justification…can admit POC
- but still balance: Mistrust of legal/criminal justice system, police??
- Intoxication: determine functioning of mind (not degree of guilt, below)
- **Use Limiting Instructions here, to clarify on both of these issues
-INADMISSIBLE:
- If issue is degree of culpability
- Ex. Manslaughter v. Murder
- Unless…large gap between offence admitted (ex. Assault v. Murder)
Consciousness of Innocence:
- Reasonable inference that Accused is not guilty, leave to Jury**
- PV - Some acts could lead to detection if guilty, depending on the type of crime (ex. DNA test in sexual assault)
- But no Right to Silence negative inferences allowed…
- NOT Admissible:
- Decrying innocence
- Consider Accused’s knowledge of state of the investigation (ex. DNA evidence destroyed in fire already)
-Principled approach: if we let Crown get bad POC in, should be easier for Def to put evidence in, so allow COI evidence leave to Jury
-Def has to be careful not to open up the door, about issue of POC/Demeanour…

(Extrinsic Misconduct) – BAD CHARACTER of the WITNESS
-On X, attempt to undermine witness:
- Reliability: accuracy of their evidence due to certain objective circumstances (even if honest)
- Ex. dark, quick, scared
- Credibility: trustworthiness of the witness
- Ex. lying, exaggerating, minimising, questionable logic, demeanour on stand
- PIS, Bias, Prior bad acts (crim record), interested in judgment (association, financial, related), other motivations
Prior Convictions
-Presumption: (depends on purpose) ADMISSIBLE if going to credibility issue – logical link
- Weight: Prior bad acts (ex. dishonesty criminal offence - fraud, obstruction)
-Onus:
- SofP:
CEA s. 12.1
- Witness can be questioned as to whether convicted of any offence
- BUT: Judge has discretion, to let in (PV v. PE)
- Factors:
- If prior offense has element of dishonesty (fraud, obstruction - PV)
- Temporal proximity
- Nature of crime (if similar to this one, more PE)
- MUST give limiting instructions on how to use evidence, for credibility
-Accused is Witness: just bring in the fact of the conviction, for credibility – cannot get into the details (unless SFE application OR Accused opens the door to talking about the offence)
- Cannot use charge for which acquitted
-Crown Witness: greater discretion to get into details of previous convictions
VETROVEC WITNESS
-Presumption: ADMISSIBLE
- Credibility weight, left to jury, find confirmatory evidence to help restore faith
-Onus:
- SofP:
-Crown witness that has inherent, profound, or serious reliability or credibility concerns, beyond regular problems – lack of morals
- Ex. jailhouse informant, lied under oath, multiple PIS, an Accomplice getting a deal, benefiting from testimony (money, jail privileges, plea bargain)
- Not for Defence Witnesses
-Linked to wrongful convictions
TEST WEIGH these Factors:
- 1) Degree of problems with Inherent Trustworthiness
- Involved in crim activity
- Delay in coming forward
- Benefit for testimony
- Series of PIS
- 2) Importance of Witness to Crown case
- More imp to Crown – lesser degree of problems needed to invoke caution
- 3) INSTRUCTIONS to JURY
- 1 – Separate the witness out from the rest, treat differently
- 2 – Identify characteristics that bring VW credibility into serious question
- 3 - Caution jury: not required, but dangerous not to use confirmatory evidence
- 4 – Look for independent evidence, to confirm other material testimony of VW
- Confirmatory/Corroborating Evidence:
- 1 – Must relate to material/relevant aspect of VW evidence
- Doesn’t have to confirm key element, but cannot be merely peripheral
- 2 – reasonably capable of restoring faith in VW
- Depends on how bad/serious, range of VW - need more CE to restore faith
- 3 – independent
- Cannot come from VW themselves, or Collusion

COMMON KNOWLEDGE / LAY OPINION EVIDENCE
-Provide information to jury to assist them in forming their own opinions, allow them to draw inferences they otherwise would not be able to do (do not understand certain issues)
-First hand, non-experts…
-Presumption:VARIES. A lot may go to weight.
-Onus:
- SofP:
-
RULE
- A Witness can provide opinion regarding something within common knowledge/average persons common experience, which doesn’t require expert qualifications
- TEST: PV v. PE
- FACTORS:
- 1 - witness is drawing logical inference from facts
- 2 – facts upon which opinion is based are too speculative
- 3 – opinion phrased as legal conclusion (invasion into trier of fact role)
- Ex. ‘too intoxicated to drive’ - as opposed to ‘seemed intoxicated’
- 4 – goes beyond common knowledge into expert evidence
- Ex. ‘was having a heart attack’

EXPERT OPINION EVIDENCE
-Provide information to jury to assist them in forming their own opinions, allow them to draw inferences they otherwise would not be able to do (do not understand certain issues)
-**Disclosure requirement for Defence here (30 days notice for all, CC)
-Presumption: Err on the side of NOT calling EE, especially for Behavioural
- DEPENDS greatly, on Mohan Balancing, and Foundation evidence
- Weight:
- Qualifications of Expert
- Only some evidence of Foundation of expert’s opinion
-Onus: party seeking to enter the EE
- SofP: BOP - each element of Mohan
-Scientific and Technical EE is more Admissible Behavioural EE is more open to attack
TEST: Mohan
-PV v. PE, with particular features
- 1) Relevant
- Of the EE, to the material issue
- 2) Necessity
- In assisting the trier of fact, in drawing inference relative to the case
- Too conclusive, too complicated – not as helpful
- Threshold is necessity, NOT helpfulness…needs to be more
- 3) Qualified
- Not usually controversial – weight issue (leading expert or not)
- Cross for bias…(paid, always on one side)
- 4) Absence of other Exclusionary Rule PV v. PE
- Manner in which it is provided may tip the balance – how articulated – concerns over Expert taking over trial, usurp role of jury
- Hypothetical Question: as opposed to giving opinions regarding the specifics of the case, crossing the line, likely inadmissible
- Unless evidence is not in dispute, or Expert has dealt directly with the Accused (ex. interviewed)
- Ultimate Issue: closer the opinion goes to ultimate issue, stricter the test for Admissibility…
- Evidence going to Foundation/assumptions of Expert Opinion:
- if none, admissibility issue
- if some, or too much psychiatric evidence/hearsay, goes to weight(even if significant – Lavallee)
Novel Scientific Evidence
-Trial judge as gatekeeper – new forms of science regarded with special scrutiny
TEST:
- Whether the science is sufficiently reliable to put before the court
- Factors:
- 1 – Has technique been tested, or can it be
- 2 – Has theory or technique been subject to peer review
- 3 – Is the error rate known
- 4 – Generally accepted by scientific community (U.S. import, Fry test)
-
Credibility of Victim – Oath Helping
-oath-helping: prohibits admission of evidence adduced solely for purpose of proving that a witness is truthful…credibility of victim is not subject to Opinion Evidence
- applies to Truthfulness of Witness (as opposed to Truth of Witness’ statements)
- Experts cannot say: find particular witness “credible”, “truthful, believable”
-Admissibility: Can still be admitted, if in addition to oath-helping it has some other legitimate purpose (if indirect to issue of credibility)
- ADMISSIBLE: Evidence about a feature of witness’ behaviour or testimony
- INADMISSIBLE: Evidence about credibility of witness

COMPETENCE and COMPELLABILITY of WITNESSES
-Presumption: Competent and Compellable – testifying is public duty, necessary to facilitate search for the truth
- Exception: the Accused – is competent but not compellable – Charter s.7, 11.c: cannot draw adverse inference from Accused decision not to testify
- Also: privilege, age, mental capacity, specific circumstances (ex. Spouse)
-
1) COMPETENCY
-Presumption: Compellable
- **Statutory presumption of capacity, for children
- Weight: no lesser weight if admitted based on promise to tell truth, as opposed to oath/SA
-Onus: Party challenging the competency of the witness must satisfy the court that there is an issue as to capacity, on BOP:
- Mental: 1) cannot understand nature of oath OR 2) unable to communicate evidence
- Children: 1) understanding 2) responding
-CL: witness must be under oath, morally bound to tell truth through oath or solemn affirmation
