I'm not sure what you mean. Suing someone isn't an act of violence.
Violence can also be confining someone to a jail cell, or confiscating (taking without voluntary consent) some or all of their property (e.g., imposing a fine on a person)
Your modern Australian courts must do this, to compel compliance with their decisions.
If you lose a lawsuit and fail to pay, then they just come and take your money and/or your possessions. If you attack the sheriff's deputies carting off your stuff, or assault the bank manager for having given away "your" money, then yeah, you are in for a world of hurt.
