Relevance and Exclusion of Illegally Obtained Evidence

Overview

A document may speak directly to the dispute and still be excluded because of how it was obtained. Conversely, an admissible recording may persuade the judge very little. Relevance (pertinence), admissibility (recevabilité) and probative weight (valeur probante) answer successive questions: does the evidence help resolve an issue, may the court receive it, and what does it establish when assessed with the whole record?

Article 2857 CCQ makes relevance the general condition for receiving evidence. Article 2858 CCQ requires exclusion when evidence was obtained in violation of fundamental rights and freedoms and its use would tend to bring the administration of justice into disrepute. Where professional secrecy (secret professionnel) was violated, that second condition does not apply. These provisions organize the inquiry without displacing the particular rules governing each means of proof.

An objection (objection à la preuve) therefore needs a legal ground. A party cannot overcome hearsay merely by saying that the statement matters, or overcome professional secrecy by saying that counsel's advice would settle the dispute. The lessons on witness testimony, out-of-court statements and objections to evidence develop those separate controls.

Learning Objectives

• Relate a proposed item of evidence to the disputed facts and the procedural stage at which it is sought.
• Apply both conditions of art. 2858 CCQ while identifying the special treatment of professional secrecy.
• Assess recordings, surveillance and confidential records without confusing exclusion, persuasive force and other remedies.

Relevance follows the issue to be decided

An item is relevant if it can influence the decision on the dispute. Start with the conclusions sought, identify the facts needed to support them, and explain the rational connection between those facts and the proposed evidence. The burden of proof (fardeau de preuve) helps identify what must be established; it does not make every fact about an opponent relevant.

The distinction between legal and factual relevance helps at different stages. An allegation has legal relevance if the governing law makes that alleged fact material to the remedy. A question or document has factual relevance if it can help prove a material allegation or, where permitted, test the reliability of testimony. An invoice might help establish the price claimed, while a witness's obstructed view might help assess that person's account of delivery.

Relevance also depends on the purpose for which an item is offered. Hearsay (ouï-dire) involves an out-of-court statement offered to establish the truth of what it asserts. A witness repeating a neighbour's explanation of an accident raises a different admissibility issue from a witness describing the words that gave notice of a hazard. Specifying the purpose permits the court to identify the applicable rule; changing the label cannot conceal a use that still depends on the statement being true.

A weak item can remain admissible

Probative weight concerns the persuasive force of evidence after its reception. A poorly lit photograph can be relevant to the condition of a staircase while proving little about whether it was slippery. Ordinarily, shortcomings of this kind belong in submissions on the merits. A complete absence of evidentiary usefulness can establish irrelevance, but a dispute about degree should not routinely become an exclusion objection.

Criminal-law balancing of prejudice against probative value should not be imported as a general civil exclusion rule. Civil trial management still matters: a marginal inquiry that creates confusion or requires a disproportionate side trial may face limits. The distinction is between a concrete problem in the proposed proof and the bare assertion that an otherwise relevant item is unconvincing.

Other admissibility rules continue to operate. Testimony about a juridical act may encounter the restrictions on oral proof; an attempt to contradict a signed writing raises a further issue; a copy can engage the best evidence rule. Article 2857 CCQ supplies the relevance requirement without converting all relevant material into permissible proof. Identify these additional grounds separately so the court can decide the actual difficulty.

The procedural stage changes the inquiry

Pleadings and amendments

An application to strike irrelevant allegations under art. 169 CCP tests whether the pleaded facts have a sufficient connection with the issues. Courts act cautiously before trial because they have only an incomplete picture of the evidence. Refusing to strike an allegation does not determine its eventual admissibility or weight, and the trial judge may still exclude irrelevant material.

Pleadings describe the case to be met. They are not a repository for every anticipated credibility attack. Article 99 CCP requires the nature and object of the pleading, its supporting facts and conclusions, and information whose omission could surprise another party or cause an unforeseen debate. A proposed allegation should do work within that structure rather than merely portray an opponent unfavourably.

An amendment under art. 206 CCP must also fit the litigation. Its relevance does not eliminate the requirements concerning delay, the interests of justice and an entirely new application unrelated to the original one. Timing matters: introducing a consequential new factual dispute after evidence has closed presents different fairness concerns from clarifying an existing allegation early in the case. A useful evidentiary connection and a procedurally acceptable amendment are distinct requirements.

Pre-trial examinations and sworn statements

A pre-trial examination (interrogatoire préalable) serves to identify issues and obtain the evidence needed to prepare the case. Article 221 CCP permits inquiry into facts relevant to the dispute and the evidence supporting them. Relevance is approached generously at this investigative stage, where the examiner cannot already know everything the answers will establish.

That generosity does not authorize an unrestricted search for a possible claim. A fishing expedition (recherche à l'aveuglette) seeks vaguely defined information without an adequate connection to the dispute. Requests should identify the relevant subject, period and documents with enough precision to explain their usefulness. Proportionality (proportionnalité) also constrains the scale of the inquiry under art. 18 CCP.

Article 228 CCP draws a practical distinction. An ordinary relevance objection generally does not prevent the witness from answering, unless it is decided immediately; the objection is recorded for determination by the court. The witness may refrain from answering objections concerning non-compellability, fundamental rights, an important legitimate interest or presumed irrelevant facts in cases alleging sexual or domestic violence. Those objections must be submitted to the court within five days. A party should not turn every broad relevance dispute into an asserted right to remain silent. Predictable objections can be determined before the examination, and art. 230 CCP permits judicial intervention against abusive or unnecessary examinations.

An examination on a sworn statement has its own scope. Article 105 CCP ordinarily concerns the facts whose truth the declarant has attested. Where the statement is used as evidence in the circumstances contemplated by art. 106 CCP, art. 222 CCP extends examination to other relevant facts. Identify the role of the sworn statement before assuming that every examination has the same investigative reach.

Questions during the trial

Article 280 CCP distinguishes examination, cross-examination and re-examination. Direct examination concerns relevant facts. Cross-examination (contre-interrogatoire) may also establish grounds for refuting the witness's testimony, including matters bearing on credibility even though those matters were not pleaded as components of the claim. This latitude does not permit harassment or humiliation disconnected from a proper evidentiary purpose.

Re-examination (réinterrogatoire) addresses new facts raised on cross-examination or explains the witness's answers to another party. Counsel who opens a subject on cross-examination can make responsive explanations relevant. A genuinely new topic may require permission to reopen direct examination, with the corresponding opportunity for the other side to question the witness. These distinctions make relevance an inquiry tied to the function of the questioning.

Earlier and later events need a specific connection

Liability is generally assessed by the circumstances existing when the disputed event occurred. A later precaution does not automatically prove an earlier fault. An admission (aveu) inferred from conduct requires sufficient clarity: installing an additional handrail can reflect caution without acknowledging that the original staircase was defective. Even where evidence of the alteration is received, its admission does not compel that inference.

Earlier negotiations may help identify the parties' intention or explain an ambiguous contractual expression. That purpose must be distinguished from using oral evidence to contradict the writing. An earlier settlement may also limit what remains in dispute; art. 2633 CCQ gives a transaction authority between its parties. The wording and scope of the settlement matter before reopening the facts it addressed.

Similar acts (faits similaires) require a rational link to the present issue. A demonstrated recurring method may help prove a disputed scheme or answer a claim of accident. General moral criticism offers much less. The court must consider the specificity of the connection, proper pleading and disclosure, possible confusion and the length of the additional inquiry. Similar incidents do not dispense with proof of the facts supporting the claim now before the court.

A judgment from criminal, penal or disciplinary proceedings likewise requires a distinct analysis. Its factual proximity to the civil dispute determines its usefulness, and a conviction concerning the same events cannot casually be ignored. Article 2874.1 CCQ provides a specific rule for an action seeking damages for injury resulting from an act constituting a criminal offence: filing a copy of the offender's judgment of guilty that has become final suffices as proof of fault. The other elements of civil liability and the amount of damages are not thereby established. This rule should not be generalized to every penal or disciplinary decision.

Filing the judgment does not import the entire evidentiary record of the earlier proceeding. Documents and testimony must be introduced through rules applicable to the civil case. A prior statement used to test credibility and a prior statement offered as proof of its contents raise different questions.

Worked application: the altered staircase

Factual Scenario

The following facts are hypothetical. A visitor sues a workshop after falling on its stairs. The workshop later adds abrasive strips. The visitor offers a photograph of those strips, a photograph taken immediately after the fall, and a neighbour's account of what someone else said about the accident.

Exclusion under article 2858 CCQ

Identify a fundamental right and its governing instrument

The first condition concerns the obtaining of the evidence. Identify the conduct, the right infringed and the legal source of that right. A breach of good faith or another illegality does not, by its existence alone, prove a violation of a fundamental right. The inquiry needs facts about the method used to acquire the item, rather than a general accusation of unfairness.

The Quebec Charter of human rights and freedoms protects private life in s. 5 and professional secrecy in s. 9. Articles 35 and 36 CCQ protect privacy and identify forms of interference, including interception or use of private communications and certain uses of a person's image or personal documents. Private life (vie privée) is not confined to the home: an expectation of privacy can persist, with varying intensity, where a person can be seen by others.

The Canadian Charter of Rights and Freedoms has a different field of application. Section 32 connects it to governmental action; s. 8 protects against unreasonable search or seizure, and s. 24(2) provides its exclusion mechanism. The Quebec civil rule can apply in disputes between private persons without transforming those persons into state actors. Keep each Charter and each remedy attached to its own requirements.

Determine whether use would discredit justice

Outside professional secrecy, a violation alone is insufficient. The second condition asks whether using the evidence would tend to bring the administration of justice into disrepute (déconsidération de l’administration de la justice). In Houle c. Mascouche (Ville de), [1999] R.J.Q. 1894 (C.A.), the Court of Appeal developed a civil analysis balancing effective protection of fundamental rights with the search for truth.

The assessment adopts the perspective of a reasonable, objective and informed person. It considers the seriousness of the infringement, why the evidence was sought and how the intrusion was carried out. Deliberate, extensive interference to advance a party's private interests can weigh strongly toward exclusion. Whether the party offering the evidence itself committed the violation also matters, without being an exhaustive or automatic test.

The method and purpose require concrete examination. Was the search targeted to a supported concern or undertaken randomly? Was a public observation replaced by entry into a private space? Were devices installed or private accounts accessed by subterfuge? What privacy interests were exposed beyond the contested issue? These facts permit a reasoned assessment of the intrusion rather than an abstract appeal to truth at any cost.

The fact that an intrusion produced accurate evidence does not erase its seriousness. Equally, the court must consider the actual consequences of exclusion for deciding the dispute. The analysis can account for the purpose served by the evidence, the surrounding lawful proof and the interests affected, including those of children where applicable. These considerations are contextual factors rather than predetermined exemptions. The party seeking exclusion should provide a factual account of the acquisition, while the party relying on the item should explain its proposed use and the circumstances said to justify receiving it.

The civil approach must not simply reproduce a criminal exclusion analysis. The functions of the proceedings, the parties and the burdens of proof differ. Exclusion in an earlier criminal case therefore does not mechanically decide admissibility in a later civil case. The civil court must apply the legal framework governing the evidence now offered.

Professional secrecy receives distinct protection

Where evidence was obtained in violation of professional secrecy, art. 2858 CCQ removes the requirement to establish disrepute. Section 9 of the Quebec Charter also requires the court to ensure respect for that secrecy of its own initiative. Establishing the scope of the protection, any valid waiver and any applicable exception therefore becomes decisive.

The inquiry does not end because a document is described as confidential. Professional secrecy, litigation privilege and settlement privilege have different conditions and effects. The lesson on protected communications distinguishes them. A court cannot bypass a protected lawyer-client communication merely because it is highly probative.

Recordings, surveillance and medical information

Identify who recorded the conversation

A participant's recording differs from interception by an outsider. A person who records a telephone conversation in which that person participates may generally use it against the other participant without that act alone constituting the privacy violation addressed in art. 2858 CCQ. This does not decide every other question about its authenticity, completeness, purpose or privileged content.

A third party's interception of a private conversation presents a different privacy problem. It calls for assessment of the infringement and, unless professional secrecy applies, the second condition of art. 2858 CCQ. The location of a telephone is not decisive: the protected interest concerns the conversation and the reasonable privacy expectations surrounding it. A work setting does not abolish all confidentiality.

Surveillance requires contextual justification

Video surveillance and following a person can intrude on private life even outside the home. An employer's legitimate need to investigate a supported concern can be relevant to the justification and proportionality of the surveillance. It does not create a general licence to record everything an employee does. The basis for suspicion, the location, duration and intrusiveness of surveillance must be examined.

Likewise, the fact that an image shows something useful does not retrospectively settle whether obtaining it was lawful. A camera observing a shared passage and a device installed to capture private activities inside a dwelling raise materially different concerns. Where an infringement is established, the court still applies the disrepute condition, subject to the professional-secrecy exception.

Medical relevance does not open the entire personal file

A party who puts a physical or psychological condition in issue can waive confidentiality over medical information needed to address that issue. Glegg c. Smith & Nephew Inc., [2005] 1 R.C.S. 724, illustrates the role of relevance in determining the information available for the litigation. Waiver (renonciation) must be examined in its context and scope; unrelated intimate details do not become useful merely because a medical claim exists.

Obtaining a medical file without lawful authorization raises a separate question from identifying information that could properly have been sought through the proceedings. Courts can control the relevant disclosure and protect confidentiality. A party should pursue those mechanisms rather than assume that a possible entitlement to some information authorizes covert acquisition of the whole file.

Worked application: the private mailbox

Factual Scenario

The following facts are hypothetical. A furniture maker disputes a customer's alleged oral price reduction. The maker has the signed estimate and several exchanged messages, but also obtains access to the customer's private mailbox and copies a confidential exchange with counsel.

Practice Checklist

• State the fact to be proved and the precise purpose of the proposed evidence.
• Identify the procedural stage and the permitted scope of questioning or disclosure.
• Separate irrelevance, low probative weight and any specific exclusion rule.
• For art. 2858 CCQ, establish how the evidence was obtained and identify the violated fundamental right.
• Address disrepute with concrete facts, unless the violation concerns professional secrecy.
• Check the scope of any waiver and seek a ruling before disclosing contested privileged content.
• Preserve the ground and context of the objection for the court's decision.
