A judge at the Harju County Court has dismissed an appeal by the Reform Party against a junior judge's decision not to register the party's new leadership in the e-Business Register.
The judge said that electronic voting cannot be used in the internal elections of NGOs, Delfi reported on Tuesday.
The matter will be debated at the Tallinn District Court.
The party's secretary general, Martin Kukk, said that the dispute is technical and does not effect the day-to-day running of the party.
Kukk said that had his party not used electronic voting during the elections, it would not have detected the fraud, which led to the expulsion of MEP Kristiina Ojuland.
Reform Party members voted in internal leadership elections in May by registering on Facebook or by email.
Ojuland was thrown out of the party shortly after being elected to the board for allegedly casting 40 e-votes on behalf of elderly party members.
