Troy Davis in court again this week

This week lawyers for death row inmate troy Davis will once again try to stop his execution. Davis execution had been halted three times. On Tuesday his lawyers will make their case to a panel at the 11th U.S. Circuit Court of Appeals.

The hearing could focus less on the Davis case, but rather on whether the lawyers have the right under federal law to ask for a new trial.

They’ve struggled to convince any rout to grant their client another hearing. Since Davis’s conviction in 1991, his lawyers say 7 of the 9 witnesses have recanted their testimony.

Davis was convicted of killing Savannah police officer Mark McPhail.
