The prosecution over the death of a worker on the new Royal Adelaide Hospital will not go to trial after the State Government dropped all charges against the hospital’s builder. The state’s construction union was this afternoon informed through the Attorney General’s department that SafeWork SA had dropped its prosecution against HYLC and sub-contractor SRG Building over the death of Jorge Castillo Riffo in November 2014. Mr Riffo was working on a scissor lift at the site when he was crushed against concrete. The prosecution against HYLC and sub-contractor SRG Building for alleged workplace safety breaches was set down for a 10-day trial from today.
