HOW MANY arrests take place at the Bentley anti-gas blockade depends as much on how police approach the situation as the actions of protesters, Lismore lawyer Steve Bolt says.
Mr Bolt said it was "largely up to the police" whether or not anyone was arrested.
Any action against police instructions, such as not moving on when asked, would result in arrest.
It is also likely police will close the road, which they did at the Glenugie protest in January 2012.
At Glenugie, police also used a common law power called "anticipated breach of the peace", which let them arrest several people for standing around.
This backfired in court because the charges were thrown out.
Whether police arrest one person or 100 depends on their strategic decisions about how to best legally and peacefully deal with the protest..
