It's interesting that your first example was from my home province. There is no shortage of bilingual lawyers in the province. The ones who practise the most en français are the ones who are employed at the national headquarters of the Department of Veterans Affairs, because they're constantly having to present in both languages.
One of the issues that is raised in one of the letters here is whether the rights under section 530 extend beyond trial to bail hearings, and I would also add appeal hearings.
I understand from the letter that is their practice.
Is it legislated, or is it just good practice, and should it be legislated?
