THIS STORY WAS UPDATED AS THE SITUATION DEVELOPED AT THE COUNTY COURT YESTERDAY.
Protestors have "civilly arrested" a judge at Birkenhead county court.
A crowd of several hundred people has massed around the court.
Police have begun forcibly ejecting protestors from the court in chaotic scenes.
Made up of people from across the UK, the marchers say they are exerting their "ancient right to lawful Rebellion under Magna Carta."
Around 20 police vehicles are now in attendance and several dozen officers are at the scene, some with dogs.
The crowd, although largely peaceful, is chanting "freedom" and "arrest that judge."
Some have sat down in the road blocking in a police van and are refusing to let it pass.
The area around the county court at Hamilton Street and Market Street is now closed to vehicles by police cordon.
The protestors are handing out leaflets from the "British Constitution Group."
The demonstration was apparently sparked when one of the prominent voices in the BCG, Wirral man Roger Hayes, faced a bankruptcy hearing for non-payment of his council tax.
The BCG's main aim is a rallying call for "lawful rebellion."
In 1997, Mr Hayes stood for election in Wallasey representing the Referendum Party against sitting MP Angela Eagle. He polled 1,490 votes and finished fourth.
The Referendum Party was a single-issue party that emerged in the 90s calling for a vote on the UK's relationship with the European Union.
One of the protestors who had travelled up for the demonstration from Coventry said: "The purpose of today is to generally to get a feel of how unsatisfied people are with the governing of the country.
"I wouldn’t say I was angry, just dissatisfied. I believe that the power is distributed unfairly at this point in time.
“I believe that the people who are in control are morally defunct.
"I don't think they are serving the interests of those they are supposed to be serving."
The BCG website says: "We, the British People have a right to govern ourselves.
"That right has been subjugated as a consequence of acts of treason having been committed by the collective political establishment, aided and abetted by corrupt segments of the judiciary, the police, the Church and the civil service."
