Yes. I'll give you the best example there is.
In my little spiel, I said that a complaint had been filed against me. The person who handled the complaint was an anglophone and didn't want to hear a word of French. When he called me, he only spoke to me in English. I was really in a bad position because the lawyer who had filed the complaint against me was an anglophone. She got along well with the investigator. However, when he called me, I wasn't happy because I didn't understand him.
That went on for three years, until they hired Mr. Setton Lemar, who spoke both languages. I informed him in writing that I was going to find a lawyer and that they were going to hear my case in French.
