But, surprisingly Anthony's defense has filed a last-minute motion asking one more thing be discussed.

Last week, Judge Belvin Perry ruled one of the state's experts will be allowed to testify as pure expert opinion. So his testimony didn't need to be brought up in this week’s Frye hearings where they question scientific evidence.

The defense is now asking the judge to take that back.

Casey Anthony's defense team filed a handful of items in her first-degree murder case late Monday, including a motion to add a state prosecutor to their witness list.

Defense attorney Cheney Mason wants Assistant State Attorney Kenneth Lewis, who handles homicide cases, added to the witness list.

Mason's motion said the defense team recently learned that Lewis may have testimony under Brady v. Maryland, which requires prosecutors to fully disclose to the defendant all exculpatory evidence in their possession.

It's unclear why the defense is seeking to put Lewis, who is not prosecuting Anthony's case, on the witness list. A call to Mason's office was not immediately returned.

The defense also wants to call Jeffrey Danziger, a well-known Central Florida psychiatrist who frequently testifies at criminal trials, as a witness.

This week’s hearings in the Casey Anthony case will focus on a lot of scientific evidence. The defense wants to keep it out of trial based upon the “Frye test.” The Frye standard is used to keep “junk science” from coming from before a jury. The landmark case of United States v Frye, requires a scientific principle or test be “sufficiently established to have gained general acceptance in the particular field in which it belongs.” This ensures that a defendant has a fair trial, and that a jury does not base its decisions on science that is unreliable.

"You look at whether or not their methods are accepted by the scientific community and you look at whether or not the principles they rely upon and engaging those methods are accepted by scientific community," Hornsby said.

Judge Belvin Perry will not determine whether or not the testimony is valid, only that the principles it is based on are accepted, Hornsby said.
