Here's an example. I said that a paragraph of a section of the Civil Code was applicable, and the interpreters said that it wasn't applicable.
In another case, I said that the rights of an individual protected by the charter hadn't been violated. The interpreter reported that the individual's human rights hadn't been violated, but didn't specify that I was referring to charter rights, which is quite different.
On another occasion, while presenting arguments, I spoke about how things are done in common law. The interpreter failed to say “common law”. This gave the impression that I was talking about civil law and it made no sense.
Those are examples of interpretation errors that make arguments very difficult to understand and follow. There's no denying it. When we argue a case before the Supreme Court, we don't have much time and we must be extremely concise and accurate. We don't have the time and opportunity to correct the errors that may occur during simultaneous interpretation.
