Four years ago, he decided the plain black robe would not suffice. A fan of Gilbert and Sullivan operettas, Rehnquist saw a local production of “Iolanthe,” in which the Lord Chancellor wore gold stripes on his sleeves. A few weeks later, he appeared in court with gold stripes stitched onto the sleeves of his robe.
What’s the meaning of the bright stripes, reporters asked of the court’s press officer. An inquiry was lodged with Rehnquist’s office. There is no meaning to it, came the reply. The chief justice just likes the look.
