Casey Anthony's lawyers are fighting her court-ordered return to Florida.
Judge Belvin Perry ruled last week that that Casey must serve out her probation for a check fraud conviction right now, in her native state of Florida.
Anthony's legal team believes she effectively served it while she sat in jail during her murder trial, and appealed the judge's order for her to return.
If they lose the appeal, Casey will have to return to Florida in 11 days.
Anthony was given a year's probation in her 2010 check fraud case, and the judge who sentenced her said in court that the time Casey spent in jail facing murder charges would not count toward completing probation.
However, the order the judge signed mistakenly allowed Casey's probation to run concurrently with her time behind bars. Thus the confusion.
The judge ruled Friday that the error was just that - an error.Perry said it wouldn't make sense to allow Casey to get credit for the time she was in jail, as the point of probation is to test how a person behaves in the real world, not locked up with few opportunities to get into trouble.
Nevertheless, her attorneys are appealing Friday's ruling.
If they win, it would mean Casey would get a huge break, as her probation would already be considered complete because of a technical error.
As a contingency, Casey's lawyers say if they lose their appeal, they want her to be allowed to serve her probation in a state other than Florida.
They believe that as America's Most Hated Person, it would be both expensive and dangerous for Anthony, who has been in hiding (in Ohio, among possible other locations) since her release, to come back to Orlando.
