SANFORD, Fla. -

An appeals court could decide whether attorneys for George Zimmerman, the neighborhood watchman charged with shooting and killing 17-year-old Trayvon Martin, can question the Martin family's attorney.

The appeals court gave the state 20 days to argue why it shouldn't consider to hear the appeal to question Martin family attorney Benjamin Crump. The defense then has 10 days to reply to the state's argument.

Judge Debra S. Nelson denied last month the Zimmerman attorneys' second attempt to force Crump to testify in a deposition about his dealing with Witness 8, the young woman on the phone with Martin in the moments before Zimmerman killed him.

Zimmerman is charged with second-degree murder in the February 2012 death of the 17-year-old Martin. He claims he acted in self defense.
