There is no doubt that Casey Anthony lied to detectives when she told them her 2-year-old daughter had been kidnapped by a babysitter.

But a state appellate court is being asked to decide Tuesday whether the Florida mother was in police custody when she made the statements that led to her being convicted of lying to law enforcement officers.

If judges on the Fifth District Court of Appeals decide she was in police custody, they could overturn her misdemeanor convictions on the grounds that her statements were inadmissible since she hadn't been read her Miranda rights. The Miranda rights warn suspects that they can remain silent and that their statements can be used against them in court.

Anthony was acquitted in 2011 of murdering her 2-year-old daughter, Caylee.
