Bumbling about the internet, I found a lovely bundle of joy in the form of a Canadian judge outlining the Sovereign Citizen concept in exacting detail.
You may remember the ‘fun’ that was had when one such came here after I reposted his rant {‘Furry Conspiracist Rant’).
The judge calls them Organized Pseudolegal Commercial Argument litigants (“OPCA litigants”), as there is a broad spectrum of such individuals and groups.
Long, but worth a read.
