Magistrates in Selby fined Messenger £200 for being drunk and disorderly and £400 for obstructing police after deciding he “squared up” to officers.
He was fined a further £200 for damaging an alarm button in a police cell and ordered to pay £188 in compensation.
Messenger was also ordered to pay more than £6,000 in court costs.
The way in which Mr Messenger responded was to behave in a totally inappropriate way
The court heard how two police officers arrested him on 2 May after he refused to leave the kitchen of the takeaway where they were attending an incident.
Messenger, of Valley Bridge Parade, Scarborough, denied all the charges. Magistrate Dr Marilyn Jones said that the evidence of the officers in the case had been “compelling”.
“We believe the evidence of the police officers and Mr Messenger was drunk.”
I maintained my innocence throughout and I still do. The court was told the convictions would mean the end of Messenger’s “judicial aspirations”.
Dr Jones added: “You don’t need me to tell you you have not only let yourself down but your profession.
“Any punishment we give you will be minor compared to the loss of your standing in the community.”
Speaking outside the court, Messenger said he intended to appeal againt his conviction while continuing to work as a solicitor.
