Judges in Georgia and Pennsylvania are trying to sort out which state has jurisdiction in a dispute over the grandchildren of former basketball great Julius “Dr. J” Erving.

At issue are the 6-year-old and 3-year-old children of Philadelphia resident Kira Clifford and Julius Erving III, who calls himself “J.” One thorny question is whether a Fayette County judge’s order demanding that Clifford return to Georgia with the children is binding.
