Room 31 at the Vancouver law courts is normally a quiet, somewhat boring place, where lawyers present brief arguments on procedural questions and spectators are rarely present.

But Friday morning was different. As a clerk attempted to organize the long list of matters on the docket, about two dozen supporters of anti-vaccine activist Dr. Daniel Nagase flooded into the courtroom and declared themselves a "common-law grand jury under the Magna Carta."

Members of the crowd, some wearing shirts reading "Purebloods Stand Together," took turns reading out a statement charging a government lawyer with obstruction of justice for attempting to have Nagase's $66.6-million lawsuit against the B.C. Supreme Court tossed out.

"The government must accept the Magna Carta as common law if pleaded as such. We are pleading such," the statement reads, repeating the typical language of pseudolegal groups like Sovereign Citizens and the Freemen on the Land movement.

After several requests from the court sheriffs to sit down and be quiet or risk arrest, the crowd filed back out of the courtroom while they waited for the judge to arrive.

As they made their way to the door, one of them turned to Michael Kleisinger, the lawyer they're accusing of obstruction, and warned him "You're in trouble." Kleisinger laughed in response, asking "Is that a threat?"

Friday's peculiar court proceedings highlight how the anti-vaccine movement has come to rely on Organized Pseudolegal Commercial Arguments (OPCA) in its attempts to fight public health measures implemented during the COVID-19 pandemic.

Legal experts have told CBC News they're unaware of any case where OPCA arguments were successful in court. At the core of these false and thoroughly debunked legal theories is the idea that followers are exempt from the authority of government, laws and the courts, as long as they know how to use the right words and phrases.

Before Friday's hearing began, one of Nagase's supporters attempted to start a conversation with a lawyer unconnected to the case, and showed him a book titled Word Magic: The Powers and Occult Definitions of Words, telling him he needed to read it.

The hearing concerned a claim filed by Nagase earlier this year, accusing B.C. Supreme Court Master Grant Taylor of violating, among other things, his "right of protection and preservation of the vessels of my bloodline [and] … the vessels of the souls of my children."

Nagase, a family physician who no longer holds a medical licence and was the subject of a public warning related to his scientifically unsupported statements about COVID-19, filed a handwritten notice of claim in May.

It accuses Taylor and the court of exposing Nagase's children to "future consequences untold and not yet realized of myocarditis, thrombosis, cancer and sterility."

An amended notice of claim filed the next month appears to hold Taylor responsible for the fact that Nagase's children received what he describes as "a prima facie medical experiment commonly known as COVID-19 vaccination."

Nagase claims that his children "have been subject to future harm enabled by wrongful orders," and asks for $33.3 million in damages for each child, plus future medical expenses, to be paid jointly by Taylor and the court.

Friday's hearing was scheduled to hear an application from Kleisinger, on behalf of the B.C. attorney general, asking for the claim to be dismissed as "unnecessary, scandalous, frivolous or vexatious" and "an abuse of the process of the court."

When Justice Margot Fleming took her seat to address the court, Nagase introduced himself as "daniel-yoshio of the family nagase," specifying that his name should be spelled without capital letters. This formulation, including the unusual punctuation, is common among people who declare themselves "natural persons," exempt from Canadian law.

/\ So would they assume anyone travelling to a different state is necessarily seeking medical services? That doesn't make sense.

It should be a crime to be this retarded.

I have a question... does a racist know he's racist.
