Casey Anthony was order to get out of hiding and return to Florida to report for probation.
Anthony must go back to Florida by Aug. 26 in order to serve her probation on a 2010 check fraud conviction.
Judge Belvin Perry has rejected claims by Anthony's lawyers that the Florida mom had already served her probation while in jail awaiting the murder trial charge in connection with the 2008 death of her 2-year-old daughter Caylee.
Reuters reported that Stan Strickland, the judge who accepted Anthony's guilty pleas in the 2010 check fraud case, had stated in open court at the time that Anthony was to serve a year of probation after her release from jail.
However, Strickland's intent that probation begin after her release, wasn't written into the final order, and he filed a clarified version on Aug. 1, following Anthony's July 17 release.
But Anthony's lawyers responded by filing an emergency motion to quash that order.
In the decision made on Friday, Perry wrote that Anthony's lead defense lawyer, Jose Baez, knew that the confusion had led the Florida Department of Corrections to allow Anthony to serve her probation while in jail awaiting her murder trial, according to Reuters.
But Reuters said the defense lawyers have claimed in court that they weren't obligated to speak up about the probation confusion.
Perry, on the other hand, said lawyers have a "duty of candor," and are responsible for ensuring that court orders are followed, and added that he wouldn't allow Anthony to benefit from the situation.
"It is very clear (Anthony) and her attorney knew she was to start her probation upon release from the Orange County Jail. Despite this fact, they took advantage of a scrivener's error which started the probation while she was being held in the jail pending trial," Perry said, as reported by Reuters.
"The defense should not be able to claim that they are now harmed by having (Anthony) serve probation at this time," he wrote.
Anthony's probation on the check fraud ended Jan. 24 and so she was able to walk as a free woman when she was acquitted of murder last month.
