R v Tran

R. v. Tran

[1994] 2 S.C.R. 951
Supreme Court of Canada — Lamer C.J. | September 1, 1994

Background

Quoc Dung Tran, a Vietnamese immigrant, was charged with sexual assault. He didn't speak or understand English well enough to follow court proceedings, so the court appointed Mr. Nguyen as his interpreter for the trial. The complainant had described her attacker as "Asian," "fat," and "clean-shaven" in her police statement, but when she identified Tran in court, he appeared slender with a mustache. The defence called the interpreter himself as a witness to testify about Tran's weight at the time of the alleged assault.

Here's where things went sideways: instead of translating his testimony sentence by sentence as instructed by both the judge and defence counsel, Mr. Nguyen answered questions in English and only gave Tran brief summaries in Vietnamese at the end of his direct examination and cross-examination. Worse, when the judge questioned the interpreter directly, that entire exchange wasn't translated to Tran at all. Tran was convicted and appealed, arguing his Charter right to an interpreter had been violated.

Issues

1. What standard of interpretation is guaranteed under section 14 of the Charter?
2. Was Tran's right to interpreter assistance violated when he received only summaries instead of full, contemporaneous translation?
3. What remedy is appropriate for a Charter section 14 violation?

The Constitutional Standard for Court Interpreters

The Supreme Court established that section 14 of the Charter guarantees interpretation that is "continuous, precise, impartial, competent and contemporaneous." This isn't a right to perfect interpretation, but it must be substantially equivalent to what an English-speaking accused would understand. The Court rejected the idea that you need to prove actual prejudice — being denied proper interpretation while your case is being decided is inherently prejudicial.

The interpretation Tran received failed spectacularly on multiple fronts: it wasn't continuous (condensed into two one-sentence summaries), wasn't precise (the first summary incorrectly claimed testimony about his face when no such testimony was given), and wasn't contemporaneous (delivered only after questioning was complete). The Court also noted that having an interpreter serve as both witness and interpreter should be avoided except in exceptional circumstances.

When Interpretation Lapses Matter

Not every interpretation problem violates the Charter — the lapse must occur when "the case is being advanced," meaning when something affecting the accused's vital interests is happening. Administrative matters like scheduling don't count. Here, the interpreter was testifying about Tran's weight at the time of the alleged assault — directly relevant to the identification evidence that was the cornerstone of the prosecution's case. This was clearly advancing the case, not some side issue.

Key Takeaway

If you need an interpreter, you're entitled to understand everything that happens in your trial as it happens — not sanitized summaries delivered later.

This case established the constitutional floor for interpreter services in Canadian courts. Courts can't dismiss Charter violations using the Criminal Code's curative provisos, and the remedy for a section 14 violation during trial is typically a new trial.
