In its first oral arguments together Monday, the newly expanded Georgia Supreme Court heard impassioned pleas from lawyers on both sides of a medical-malpractice case in which one side is accusing the other of calling a surprise witness to create a “Perry Mason” moment.

“We’re here today because of the decision of the plaintiff to deliberately and intentionally withhold until the moment of ambush at trial—as in the old Perry Mason movies with Paul Drake or Della Street, if you remember them walking down the aisle with important alibi information,” said medical-malpractice defense attorney Paul Weathington of Weathington McGrew. “I’m sitting there with my associate when Savannah Sullivan’s name was called.”
