Police and picket lines
Police have no responsibility for the removal of a picket line but may act to remove a physical obstruction.
According to Victoria Police operating procedures, a picket line becomes a physical obstruction when it denies access to or egress from the particular location to any person who has a legal right (which can be anybody on a public street) to enter or leave.
Victoria Police have an Industrial Disputation Liaison Officer in the Community and Cultural Division who is brought in to liaise and advise on industrial disputes and union pickets.
