John Banks has reportedly been summoned to court over a private prosecution against the Act Party leader for alleged electoral fraud.
Judge Ian Mill said in a decision released today that there was sufficient evidence to call Banks before the court, APNZ reported.
"Access to the courts for the purposes of private prosecutions is an important safeguard against the abuses of the executive's prosecutorial discretion ..." Judge Mill said.
The private prosecution was filed by Graham McCready, a retired Wellington accountant, on a charge of knowingly filing a false election return.
The case relates to donations made to Banks for his campaign for the Auckland mayoralty in 2010, which were recorded as anonymous.
Banks was investigated by police this year over the donations, but they decided not to prosecute.
