The high court rejected Gementera’s appeal Monday of a lower court’s sentence that the San Francisco resident stand outside a post office for 100 hours wearing a sandwich board that reads: “I have stolen mail. This is my punishment.”

In February 2003, Judge Vaughn Walker of the Northern District in San Francisco added the sandwich-board penalty to Gementera’s sentence of two months in prison and three years of supervised release. Gementera had pleaded guilty to charges that he stole mail in San Francisco and the nearby city of Burlingame in May 2001.
