A bid to take a private prosecution against mayor of Auckland Len Brown has suffered a setback with the High Court saying it is not a criminal matter.
Wellington man Graham McCready is trying to get a case before the courts alleging corruption and money-laundering.
Mr McCready says he'll seek a judicial review of the court decision, because he would struggle with the alternative of taking a civil case.
He says civil cases carry higher fees, and he would also need to hire a lawyer.
The mayor's office is making no comment.
