Blacklisting is no longer an industrial relations issue; it is a conspiracy between multinational construction firms, the police and the security services...The police collusion in blacklisting is not one or two rogue officers, but standard operating procedure by the state to target campaigners under the guise of "domestic extremism", routinely sharing information with big business. About 400 environmental activists have recently discovered themselves on the blacklist...Who knows what information will be passed on to private companies? Only a full judge-led public inquiry with a remit to unravel all the institutions responsible for blacklisting is going to get to the truth of this ongoing human rights scandal.[refers to Carillon]
