Tasmania police have dropped charges against former Greens leader Bob Brown over a protest at a logging site in the state's northwest.
The 71 year old was among several people charged at the Lapoinya State Forest in January after he failed to comply with directions to leave a business access area - contrary to a section of the Workplaces (Protection from Protestors) Act.
Police Commissioner Darren Hine, on Tuesday night, released a statement saying the decision not to proceed with the charge was made after legal advice from the DPP.
"In this case the DPP observed that it was difficult for police officers to determine whether a person was in a business access area or on business premises," the statement said.
Similar charges against four others in relation to the Lapoinya protests will be reviewed.
