Justice Elana Kagan, the youngest justice at age 53, let the digital cat out of the bag during a talk at Brown University on Tuesday.
Here's how the AP reports it:
"The justices are not necessarily the most technologically sophisticated people," she said, adding that while clerks email one another, "The court hasn't really 'gotten to' email."
Instead, a "chambers aide" delivers memos printed on ivory paper among justices. No word on the court's budget for feathered quill pens and ink pots.
