He was supposed to be doing his civic duty and sitting on a jury - instead James McAllister has been sentenced to 10 days in prison.
The engineering consultant was sentenced to jail yesterday after refusing to take the juror's affirmation at the Auckland District Court on Wednesday.
Judge Nevin Dawson said McAllister had approached the bench to say he couldn't sit on the jury because he was "busy at work".
The judge did not accept the excuse and told McAllister to take his seat in the jury box.
But when it came time for the jurors to take the oath or affirmation, McAllister refused both.
"Your response was you would not be impartial because you were under duress ... and you could not deliver a fair decision," Judge Dawson said.
The judge stood McAllister aside on Wednesday and tried to get another juror, but by that stage the panel had been sent home and he was forced to adjourn the trial for the day.
The trial began yesterday after the 12th juror was selected and McAllister was sent to the cells for the day, despite telling the judge he would now be able to sit on the jury.
McAllister's lawyer David Jones QC said his client attended court for jury service on Monday and Tuesday but was not selected.
He said court staff told McAllister that there were no trials on Wednesday so he made no alternative arrangements for his demanding work schedule that included a site visit where a "near-miss" had taken place the week before.
Mr Jones said McAllister declined to hear the trial because the work pressures would have made him go along with what everyone else said.
"It was not a question of trying to play the system or antagonising the court - he was simply trying to be honest."
Judge Dawson said he found McAllister had been in contempt of court twice - once for refusing to take the oath and then for offering to sit on the trial.
"Not withstanding the explanation given by Mr Jones - the details of which you did not tell me yesterday - I'm still of the view that you failed to serve your civic duty."
He said McAllister had deliberately tried to avoid jury service because he wanted to be at work.
The maximum fine for failing to turn up to court under the Juries Act is $1000, and has only been imposed once.
But Judge Dawson said that did not reflect the cost to the taxpayer of losing a court day, and would allow McAllister to achieve what he had set out to do.
Instead, Judge Dawson sentenced McAllister under the Criminal Procedures Act to 10 days in prison.
Mr Jones said he would be filing an appeal in the High Court today and Judge Dawson agreed to allow McAllister out on bail while that happened.
Outside court, McAllister's wife Dr Agata Errera said her husband had been punished for his honesty.
"I feel he's being made an example of, as the judge is trying to encourage people to be jurors ... The fact is people have excuses and complicated things going on in their lives."
She said the couple had only recently returned from overseas to find the jury summons in the post, and had little time to make arrangements.
"It was never his intention to be in contempt ... We're not lawyers, this is an environment we're not familiar with."
McAllister said he would save his comments until after his appeal had been heard.
