The Casey Anthony case returns to a central Florida courtroom on Tuesday.

Anthony's lawyers, Cheney Mason and Lisabeth Fryer, will ask a state appeals court to throw out her convictions for lying to the police. The jury in her murder trial convicted her on four charges of lying to law enforcement.

Mason and Fryer say it should only be one charge because it's otherwise considered double jeopardy.

The outcome of this hearing could also decide if Anthony, 26, will have to testify in another trial. She has refused to answer questions in a defamation lawsuit filed by Zenaida Gonzalez.

Her lawyers say any answers could jeopardize her appeal, which prompted Gonzalez's lawyers to have their trial delayed until after the appeal.

Anthony is not expected to be in court for Tuesday's hearing in Daytona Beach.

No ruling is expected at the 1:30 p.m. hearing.
