On Monday morning[ Today], 24 activists from Extinction Rebellion sat outside Inner London Crown Court carrying placards with the same message borne by Ms Warner.
The activists said they also handed in a letter to the court stating their intentions.
Lawyer Tim Crosland, who was disbarred for leaking a draft judgment about the building of a third runway at Heathrow Airport, said the protesters had chosen to be outside the court during another Insulate Britain trial to test Judge Reid.
He said: “He’s backed off, he’s left us alone. He’s exposed himself as an unprincipled bully. Because if he really believed that those signs were interfering with the courts of justice, it was his duty to stop us. And he didn’t.
“Think about what it means for Trudi and others who’ve been arrested. Those prosecutions are completely unsustainable, assuming we don’t get arrested now.”
The protesters, made up of doctors, lawyers and Quakers as well as a rabbi and a former police officer, sat in a row along the pavement outside the court premises showing their placards to passers-by.
