A crime does not need a victim to be considered illegal, despite what "sovereign citizens1" are telling Australian police when pulled over for driving offences.
In a Facebook video (screenshot here2), a man in South Australia is stopped for driving an unregistered vehicle, but refuses to accept police authority.
He cites sovereign citizen theories 3when refusing to comply. "The law that you say is not a law," the man says (video mark 2min 36sec). When told he will be arrested, he says: "It's not a crime. Where is the victim?" (video mark 2min 53sec).
In sharing the video, the poster repeats the claim, stating: "A crime needs a victim. Where is the victim?"

Legal experts told AAP FactCheck the claim that a crime needs a victim, or an injured party, isn't backed up by Australian law, calling the views of sovereign citizens "pseudo-legal arguments".
The sovereign citizen movement originated with US anti-government groups in the 1970s4 and believes its members are "immune" from government rules5 and can refuse to accept enforcement of the law6.
Christopher Corns7, a legal professor at La Trobe University, told AAP FactCheck the post's claim was false.
"It is legally incorrect that for a crime to be a crime there must be a victim," Dr Corns said in an email.
Harry Hobbs8, 9a law lecturer at the University of Technology Sydney who has researched10 and discussed11 sovereign citizens, 12also said the claim had no substance.
"There is no requirement under any Australian law (state or federal) that a crime must have an injured party," Dr Hobbs told AAP FactCheck in an email.

Dr Hobbs said there was no legal basis in claiming a law was not a law or you "do not consent", as the man in the video repeatedly states.
"There is also no requirement that you must consent to a law before it operates upon you. If you are in Australia you must abide by all laws that have been passed by the parliament and have received Royal Assent13," he said.
Dr Hobbs said there were many examples of so-called "victimless" crimes including drug possession and use.
Dr Corns cited the Victorian Crimes Act 195814, 15which includes categories such as conspiracy (page 339), incitement (page 345) and attempts (page 351), which he said "do not require a victim."
He said there were also "hundreds of 'regulatory' criminal offences or 'strict liability' offences where the offender does not even need to have a specific intention (Mens Rea16) 17and there does not need to be a victim".

Tim Prenzler,18 a criminologist at the University of the Sunshine Coast19, said many offences were aimed at preventing harm to others rather than a specific victim.
"There is a large body of law which is preventive in terms of reducing risk through licensing, registration, operating rules and other forms of regulation," Professor Prenzler told AAP FactCheck in an email.
"You could say that the breaches or crimes that occur under this type of legislation are 'victimless', in that there are no direct victims, but lots of people were probably potential victims - of dangerous driving for example."
US law enforcement has warned about the dangers20 of the sovereign citizen movement and police have been killed at traffic stops21.
A 2015 NSW Police report called the movement a "potential terrorist threat" 22and the COVID-19 pandemic sparked a rise in groups23 in Australia.
In a 2021 Queensland District Court decision24, a judge dismissed a sovereign citizen's straw man argument25 in a drug possession case, calling it "nonsense".
Sovereign citizen traffic stop cases similar to the one in the Facebook video have also failed in court in the United States 26and New Zealand27.

Sovereign citizen adherents have described their beliefs as a "get out of jail free" card28, 29but Dr Hobbs said that was fantasy.
"It connects neatly with the other pseudo-legal nonsense about the law being a contract, that the state law is defective in some way, etc. It does not work and will likely only lead to more problems for people who invoke it as a get out of jail free card."
AAP FactCheck has previously debunked another claim30 about traffic laws from the same Facebook user.
False - The claim is inaccurate.
