The judge may overrule a jury's verdict, but this hardly ever happens. A not guilty verdict by a jury can't be challenged by the prosecution or by anyone else. A guilty verdict may be challenged by the convicted party and taken to appeal. If it's felt by the judge that there's been a mistrial, well that's different. That has not happened in this case. You or I may "review" a verdict, Nigel, but no-one has the power to intervene to change that verdict. What we are discussing here is right-wing Tory Party petulance at a verdict they don't like. No doubt the same cabal would have stood up for Colston himself had he been on trial.
