Attorney Geoffrey Farquharson did not get a one-third reduction from his 14-day contempt of court sentence.
Justice Bernard Turner had calculated that Farquharson would spend 10 days in prison with time off for good behavior.
However, the court was informed that the prison only granted remission on sentences over a month.
Farquharson was scheduled to be released on Thursday.
He was representing Christopher Butler in a murder and attempted murder trial when he was sent to prison for failing to meet a June 26 deadline to pay a $2,000 fine to purge his contempt.
Farquharson was given 21-days to pay the fine, but he said he had "no intention" of paying it. In an interview with The Nassau Guardian prior to his incarceration, Farquharson said he was not paying the fine on principle because he had done nothing wrong.
The murder trial was scheduled to resume yesterday.
Turner cited Farquharson for contempt in relation to remarks that he made on May 15, 2013 and July 18, 2013 that impugned the integrity of the court.
In sentencing on June 4, Turner said that he was compelled to punish Farquharson to spare another judge from the same behavior.
He said that Farquharson was unrepentant in his behavior by maintaining that he acted properly.
On May 15, Farquharson said, "We are concerned that the apparent bias of the court may be tantamount to participation of the court wittingly, or unwittingly, to this perversion of justice.
"We say that what the prosecution has done is to fix this man up with a case, and that the court, by its actions, may well be viewed by a disinterested observer to be enabling that effort by the prosecution.
"If that is the case, my lord, that would mean that there was a suggestion that the court itself may be guilty of a conspiracy to pervert the course of justice."
On July 18, Farquharson accused the court of "blatantly and flagrantly disregarding the law and making up the law on which it purports to act".
