A victim's rights group says it has been approached by a number of lawyers offering their services to people considering legal action against the state.
In June, the sole survivor of the Panmure RSA robbery, Susan Couch, won a Supreme Court appeal allowing her to sue the state for negligence.
The Sensible Sentencing Trust says it is aware of about 12 victims of crime who are considering similar action.
It says initially 12 lawyers were offering free legal advice to people in that position, but that number has grown.
The group says victims of crime have felt in the past that they were unable to hold anyone accountable, but the Sue Couch decision has proven that is wrong.
