Sexual Assault Defence

Sexual assault cases involve special legal rules. The defence is not limited to placing one version against another. It requires a structured analysis of consent, evidence, constitutional rights, communications and the rules of admissibility.

The objective is not to turn the trial into a moral debate. The objective is to determine whether the evidence actually permits the finding of guilt beyond a reasonable doubt.

1. The Burden of Proof Remains on the Prosecution

The accused does not have to prove innocence. The prosecution must prove every essential element of the offence, including the alleged acts, their sexual nature, the absence of consent and the required state of mind of the accused.

The defence may therefore seek to show that an essential element has not been sufficiently established or that a reasonable doubt remains when the evidence is considered as a whole.

2. Communicated Consent

Under Canadian law, consent is the complainant’s voluntary agreement to the sexual activity in question. It must be contemporaneous, voluntary and connected to the specific activity.

The concept of communicated consent is central in many cases. For the defence of honest but mistaken belief, the issue is not only what the accused subjectively believed. The court must also analyze what was communicated through words or conduct and the reasonable steps taken to ascertain consent.

3. Honest but Mistaken Belief in Consent

This defence is strictly limited. It cannot be based on silence, passivity, wilful blindness, recklessness, voluntary intoxication or a general notion of consent given in advance.

The evidence must raise a genuine legal issue: were there facts capable of supporting a belief that consent had been communicated, and were reasonable steps taken in the circumstances?

4. Credibility and Reliability: Two Distinct Analyses

In many cases, the analysis depends primarily on testimony. Credibility and reliability are not the same.

Credibility concerns the witness’s apparent sincerity. Reliability concerns the accuracy and strength of the account: memory, context, consistency, details, omissions, contradictions, substance use, delay, documents and independent evidence.

A properly prepared cross-examination does not rely on stereotypes or general attacks. It tests the relevant evidence within the limits imposed by law.

5. Evidence of Prior Sexual Activity

Evidence of the complainant’s prior sexual activity is strictly regulated. It cannot be used to suggest that a person was more likely to have consented or is less worthy of belief because of their sexual history.

In limited circumstances, evidence relating to the relationship context or communications may be relevant to a specific issue. A prior court application may nevertheless be required.

6. Private Records, Messages and Communications

Text messages, emails, screenshots, photographs or private communications may sometimes play an important role. Their admissibility is not automatic.

When the defence possesses records or communications that engage the complainant’s privacy, the court may have to apply a screening procedure. That procedure seeks to balance privacy, the complainant’s dignity, the public interest and the accused’s right to make full answer and defence.

7. Police Statements and Constitutional Rights

The defence must also examine how the evidence was obtained: arrest, detention, right to counsel, right to remain silent, interrogation, search of a phone or seizure of documents.

If evidence was obtained in breach of constitutional rights, an application to exclude it may sometimes be considered, depending on the circumstances.

8. A Strategy Tailored to the Case

There is no universal defence to a sexual assault charge. Some cases concern identification. Others concern consent, credibility, reliability, communications, intoxication, memory or the admissibility of particular evidence.

The analysis must therefore be individualized and based on the actual evidence, not on general assumptions.
