Renee-Margaret Slater went on trial accused of entering a mannequin as a candidate in last year's city council election in Aberdeen.
The 64-year-old lodged the name of Helena Torry on an official nomination document and delivered the paperwork to the returning officer at the city town house.
The former Labour councillor went on trial facing a charge under the Representation of People Act 1983 earlier this week.
However, the pensioner was cleared of the offence because the sheriff ruled the charge was not relevant to the case.
Defence lawyer Gregor Kelly argued the charge against his client related to parliamentary elections and local government elections in England and Wales.
Sheriff Peter Hammond upheld the submission his client had no case to answer.
Following the hearing, Mrs Slater said: "I just want to thank the people who helped out, the friends of Helena Torry who raised the funds for it. I couldn't get legal aid.
"She ended up with a personality, and certainly has more charisma than some politicians. It has been really stressful. It has been worrying but it has been very interesting."
The dummy was rolled out on a wheeled stand in to the court room during the trial.
Spectators sitting in the public gallery chuckled as the smiling mannequin was positioned as a production next to the witness box. It was taken into custody on April 19 after Renee was taken to the police headquarters for questioning.
Police were called in after nomination paperwork was handed in to returning officer Crawford Langley in March.
The document was handed in an hour before the 4pm deadline on March 29.
The court heard one of two documents handed to the returning officer named Mrs Slater as the candidate's agent.
And the paperwork stated Helena Torry was being nominated to stand in the Hazlehead and Queens Cross ward.
Giving evidence, Mr Langley said the form was allowed to be processed because he believed it was a valid entry. The court heard the Notice of Polls, which lists candidates, had to be republished when he became aware of a potential issue the following day.
Yesterday Grampian Police Constable Robert Chrystal said Ms Slater told officers she had not registered the dummy out of malice.
The court heard she told officers: "It was never done for any malice. It was meant to be a bit of humour and fun during a very austere election process."
The police officer told the court he asked Ms Slater to take them to where the dummy was being stored so they could take possession of it.
The dummy was registered to stand as a voice for the "silent majority" and the equality of citizens.
Mr Langley said in a statement: "I am obviously disappointed the case against Renee Slater was dismissed by the court on the grounds there was no case to answer.
"It is important to understand this decision was based on a strict legal technicality in the way the charge was framed and the court did not consider the facts of the case or give a ruling on legality of nominating a non-human candidate. If faced with the same situation again, I will have no hesitation in referring the matter to the police."
A spokeswoman for the Crown Office said: "The accused was acquitted after trial following legal submission. The Crown is currently considering the decision of the Court. The release of any productions in this case will be dealt with by the procurator-fiscal in due course under usual procedures."
