The outcome of a criminal case often depends on the reliability and admissibility of the evidence. What seems convincing at first can quickly unravel under scrutiny. A skilled defence lawyer protects the accused by testing the Crown's case and ensuring that only reliable, legally obtained evidence is considered.
Understanding the Disclosure Process
The Crown's duty to disclose all relevant evidence to the defence is a cornerstone of the Canadian justice system. This obligation stems from R v Stinchcombe and governs disclosure in criminal prosecutions. The prosecution must provide everything in its possession, even material that may harm its own case, because without proper disclosure the accused cannot prepare a proper defence.
Initial disclosure is only the beginning. It includes the results of the police investigation, but it is rarely complete. Defence counsel must review the material to find gaps or missing evidence that may affect the case, looking carefully for what has been left out and making precise requests for the information that is missing.
How Your Defence Scrutinizes Evidence
A thorough defence includes a strategic investigation across several fronts:
- Forensic review: all forensic evidence, including DNA, fingerprints, and digital records, must be assessed, including the chain-of-custody protocols used to handle it.
- Witness credibility: testimony is not infallible. Effective cross-examination can reveal inconsistencies, biases, or memory problems that undermine a witness's reliability.
- Charter challenges: Section 8 of the Charter protects against unreasonable search and seizure, and Section 10 protects the right to counsel on arrest. Where evidence is obtained in violation of these rights, counsel can bring a motion to exclude it.
- Independent experts: the defence may retain private investigators or expert witnesses to develop new information or challenge the Crown's findings.
Challenging the Prosecution's Narrative
The Crown must prove guilt beyond a reasonable doubt. That standard requires more than simply presenting evidence; it requires a coherent and convincing narrative. A defence lawyer works to break down the prosecution's version of events by exposing weaknesses and offering alternative interpretations, creating the doubt that may lead to an acquittal.
The smallest details matter, and unchallenged evidence can decide a case.
An accused person should retain counsel before the first court date so that the lawyer, not the accused, makes the disclosure requests and begins analyzing the evidence early. Direct evidence proves a fact directly, while circumstantial evidence requires inference; both are valid in court. Do not let the evidence in your case go unchallenged.
