I've been experimenting with the lawful money argument on a notice of reassessment with Canada Revenue agency. I made a brief reference to it in my second last letter to them, and in his reply the agent refused to even consider it. This time, I made the last letter to him almost purely about that, minus demanding the he address the issue of improper service of documents, and an address change. As well, the agent was notified that the Minister of national revenue was being notified to provide additional oversight in the matter.
I also wrote to the minister of National Revenue to provide oversight to the file, as it seems that it is not being handled properly. As well, I requested a ministerial discharge from the taxes, penalties, and interest that can be granted due to errors by CRA, etc. The provision for this can be found in the Financial Administration Act subsection 22(2).
So, we will see what happens. David might get his wish after all.... A protest letter to a taxation agency based solely upon the idea of lawful money.

I can post the last letters sent if anyone wants to see them.
