General Principles

See also: Inferences and Direct Evidence

Circumstantial evidence refers to any evidence from which one or more inferences are to be drawn to establish material facts.[1]

While there is no burden to prove every piece of evidence on a standard of beyond a reasonable doubt, in order to convict on a circumstantial case, a judge must be satisfied beyond a reasonable doubt that the only rational inference that can be drawn from the circumstantial evidence is one of guilt.[2]

Circumstantial evidence may be used to support the inference of innocence as well as guilt so long as the probative value outweighs prejudicial effect and it is not given undue weight.[3]

Examples of circumstantial evidence:

  • motive (past hostility to victim)
  • opportunity (including exclusive opportunity)
  • means, capacity and skills
  • post-offence conduct (flight, false alibi, destruction of evidence)
  • knowledge and state of mind
  • habit[4]
  • disposition for violence by victim
Inference vs Speculation

Circumstantial evidence is based on reasoning and inference-drawing through probability.[5] The judge must apply logic, common sense and experience to the evidence. They must consider the inherent probabilities and improbabilities, frequently eliminating the possibility of coincidence.[6]

The judge in his or her analysis must "separate inferences from speculation."[7]

Strength of Inferences to Establish a Fact

The rule of circumstantial evidence does not apply to each piece of evidence but rather only the totality of the evidence.[8]

A conclusion cannot be found without evidence, which is to say that it cannot be speculation.[9]

The strength of the inference made from circumstantial evidence depends on the relationship between the circumstantial evidence and the rest of the evidence.[10]

Proof by circumstantial evidence requires consideration of the evidence as a whole and not in part.[11]

The strength of the inference to be drawn from a single piece of circumstantial evidence depends on its context amongst all the other evidence.[12]

The whole of all the evidence may be more compelling than the sum of its parts.[13]

Juries

A judge does not need to give special instructions for circumstantial evidence.[14]

There is also no need to explain circustantial evidence in any sort of formulaic manner. It is sufficient just to use the language of proof beyond a reasonable doubt.[15]

Types of Evidence

Evidence of prior violence by the victim, including threats, can be relevant circumstantial evidence to establish the reasonableness of an apprehension of harm and could not otherwise protect themselves from harm.[16]

Drug paraphernalia found with drugs can be relevant to support the inference of knowledge of the nature of the drugs, participation in drug dealing, and specific plans of dealing.[17]

Fingerprint evidence can infer that the person who the fingerprint matches touched or held the object it was found on. It is other evidence that will determine the time and place that the object was touched or held.[18]

Standard of Appellate Review

The standard of review of any instructions on the drawing of inferences of knowledge in a circumstantial case is "whether the trier of fact, acting judicially, could reasonably be satisfied that the accused’s guilt was the only reasonable conclusion available on the totality of the evidence". [19]

Inference on an Ultimate Issue Establishing Guilt

It is usually put forward to establish a fact that can be used to suggest facts that, if established, would resolve a matter at issue.

In order for a judge to convict on only circumstantial evidence, the "circumstances must be consistent with guilt and inconsistent with innocence"[1]

The modern rule of circumstantial evidence requires that before a conviction based on circumstantial evidence can be entered the trier-of-fact must be satisfied beyond a reasonable doubt that the guilt of the accused is the only reasonable inference from the proven facts.[2]

The reverse of the principle is also true, where "there is exculpatory evidence. One piece of exculpatory evidence might not be sufficient to raise a reasonable doubt but the cumulative effect of a number of pieces of exculpatory evidence may well do so."[3]

Inferences Must be Reasonable

An inference is a deduction made from the evidence[4] or the absence of evidence.[5]

It is said that only "reasonable inferences" are permitted. Those inferences can be logically based on the evidence or lack of evidence and are assessed in light of "human experience" and "common sense."[6]

Alternative inferences must be reasonable. It is not sufficient that they be just "possible."[7]

Inferences from Absence of Evidence

Inferences consistent with innocence do not need to arise from proven facts.[8] To require proven facts wrongly places the burden upon the accused to prove what happened rather than simply raise a doubt.[9]

Cumulative Effect of the Evidence

The Court must look at the cumulative effect of the evidence and not in piecemeal.[10] Considering piecemeal means that evidence can be "reasonably or rationally explained away". However, it avoids the question of whether on the whole does the evidence prove ultimate guilt on a standard of beyond reasonable doubt.[11]

Some evidence may be explicable without guilt, and it may relate to a necessary chain of proof. However, it must be viewed in the context of all the other evidence.[12]

Inference of Guilt is The Only Reasonable One

The judge must make an inquiry into whether an inference of guilt is the only reasonable inference available on the facts, which requires consideration whether there are alternative inferences capable of raising a reasonable doubt.[13]

Example
Presence in Vehicle

Evidence putting the accused in a vehicle in which it is established that someone from the vehicle committed an offence is not enough to establish guilt where there is evidence suggesting other persons in the vehicle could be responsible.[14]

Example
Fingerprints

The mere finding of fingerprints on a household item moved during a break and enter can be sufficient to establish guilt.[15]

Inferences Drawn from Absence of Evidence

The court may consider "other plausible theor[ies]" and "other reasonable possibilities" which are inconsistent with guilt. These possibilities "must be based on logic and experience applied to the evidence or the absence of evidence."[16] This means that the Crown may need to negative "reasonable possibilities", however, this does not extend to require the Crown to "negative every possible conjecture."[17]

It must be kept in mind however that as a rule the "absence of evidence is not evidence of absence."[18]

Rejecting Alternative Inferences

It is the responsibility of the trier-of-fact to decide whether an alternative interpretation of the evidence is reasonable enough to raise a doubt.[19]

Hodges Rule

Common Law Hodges' Rule

The Hodge's rule test states that guilt can only be found where the judge is "satisfied that the facts were such as to be inconsistent with any other rational conclusion than that the prisoner was the guilty person."[1]

The original common law requirement of proof for a finding of guilt in circumstantial case is based on the rule in hodge’s case.[2]

Hodge's rule does not apply to determine the mens rea (including the accused's intention) for an offence.[3]

Hodge's rule should not be applied to test the accused's explanation for his acts.[4]

The Hodge's rule is not the "inexorable rule of law in Canada". It is only one manner of phrasing the essential test of proof beyond a reasonable doubt.[5]

Canadian Adoption

The Rule from Hodges was adopted in Canada and characterized as a test that requires that "conclusions alternative to the guilt of the accused must be rational conclusions based on inferences drawn from proven facts."[6]

The US and UK Rejection

It should be noted that both the US and the UK have long since abandoned the test from Hodges rule.[7]

Motive

Motive is a form of ulterior intent that permits the inferential proof of other essential elements of the offence. Evidence of a motive to commit the offence is circumstantial evidence supporting a conviction.[1] Conversely, evidence of a lack of motive is circumstantial evidence supporting an acquittal. Evidence of a lack of motive is not the same as lack of evidence of a motive.[2]

Evidence that the accused and victim had a good relationship is not evidence of a lack of motive, but a lack of evidence of a motive.[3]

Evidence of motive goes to prove intent as well as the act.[4]

Evidence of insolvency or debt can be admitted to establish motive for an offence of theft, fraud or arson.[5]

Evidence of the accused previously threatening the victim is admissible to establish an animus and motive to harm the victim, an intent to kill, as well as narrative. It is not bad character evidence.[6]

In a murder case, evidence of a prior abuse that establishes an animus or motive to kill is admissible against the accused.[7]

State of Mind

Evidence of an utterance by the deceased victim goes to the state of mind of the victim.[1]

A complainant's post-even demeanour or emotional state is admissible and may be used to support the credibility of the complainant's evidence of a sexual assault.[2]

Means, Capacity and Expertise

Evidence of the accused in possession of the weapon of the offence at a time outside of the offence time is admissible to prove that the accused had the necessary means to commit the offence. Without further details it cannot be put to establish that he had the weapon of the assault or that he be convicted for the offence.[1]

Evidence of tools and gear in possession of the accused consistent with the offence is evidence of expertise.[2]

  2. ↑ R v Davison, 1974 CanLII 787 , per Martin JA

Opportunity

Opportunity evidence is a form of circumstantial evidence.[1] Evidence that tends to show the presence of an accused at or near the location of the offence near in time to its commission is "relevant, material and prima facie admissible", even if it does nothing to suggest exclusive opportunity.[2]

Opportunity alone cannot be sufficient to make the case, even when in combination with motive.[3]

The accused is always permitted to counter evidence of opportunity with evidence of personal capacity, evidence of equivalent or superior capacity.[4]

Last Person Present With Victim

Where the accused is the last person seen with the victim is circumstantial evidence of opportunity.[5]

  4. ↑ Doodnaught, supra, at para 68
  5. ↑ R v Stevens, 1984 CanLII 3481 (ON CA), 11 CCC (3d) 318, per Martin JA

Exclusive Opportunity

Evidence that establishes only a single person was present at the time of the offence and was otherwise capable of committing the offence, then it will be sufficient to prove the identity of the culprit and may prove guilt beyond a reasonable doubt.[1] The issue is whether the opportunity is truly "exclusive" and not simply a likely among several potential persons. This will often address factors such as who had access to the location of the offence as well as the timing of events and each person's location during or near that time.

Evidence of opportunity that is not exclusive is akin to evidence of motive. It cannot be used as a form of corroboration.[2] However, where opportunity is coupled with some other form of inculpatory evidence, then it may be sufficient.[3]

  1. ↑ R v Doodnaught, 2017 ONCA 781 (CanLII), 358 CCC (3d) 250, per Watt JA, at para 70 ("Evidence of mere opportunity to commit an offence is one thing, evidence of exclusive opportunity to commit an offence quite another. Indeed, evidence of exclusive opportunity, on its own, may be sufficient to prove the guilt of an accused beyond a reasonable doubt")
    R v Imrich, 1977 CanLII 27 (SCC), [1978] 1 SCR 622, per Ritchie J, affirming (1974), 1974 CanLII 42 (ONCA), 21 CCC (2d) 99 (Ont. C.A.), per Schroeder JA.
  2. ↑ R v Ferianz (1962), 37 CR 37 (Ont. C.A.) (*no CanLII links) (“Evidence of opportunity, unless it is exclusive opportunity, is on a somewhat similar footing as evidence of motive. Mere opportunity is not accepted as corroboration where corroboration is required or desirable....”)
  3. ↑ R v Yebes, 1987 CanLII 17 (SCC), [1987] 2 SCR 168, per McIntyre J ("where evidence of opportunity is accompanied by other inculpatory evidence, something less than exclusive opportunity may suffice.")
    See R v Johnson, 2004 NSCA 91 (CanLII), 188 CCC (3d) 214, per Oland JA

Victim's Tendency for Violence

A history of threats by the victim to the accused to admissible for the purpose of establishing the reasonableness of the accused apprehension of harm and the accused's belief in no alternatives to the commission of the criminal acts.[1]

Evidence of tendency is even admissible where self-defence is not an available defence.[2]

Form of Evidence

Demeanor

Demeanour evidence may constitute circumstantial evidence of guilty knowledge.[1] The judge should consider the nature and context of the observations, such as a person's natural display of nervousness common to interactions with police.[2]

Drug Purchase Calls

DNA

Expert testimony of DNA evidence found upon an object will typically be considered accurate.

The defence challenge would more regularly be upon the possibility of accidental DNA transfer.[4]
