The Crown Prosecution Service has launched a high court challenge to the decision by a judge last year to let the Euston tunnellers walk free after their trial.
The highly unusual move, which seeks a judicial review of the decision to dismiss charges against six HS2 protesters who spent a month in tunnel in front of Euston train station, has led to claims by environmental activists that the CPS is interfering with the right to protest non-violently about the climate emergency.
