<blockquote>
  <p><strong>MR. OLDHAM</strong>: Well, Your Honor, I think you
  could do one of two things. You could always certify
  the question with the Court of Criminal Appeals if you
  thought that the question -- that the answer turns on
  what the Texas procedures are and that the parties
  disagree with them.</p>
  
  <p><strong>JUSTICE BREYER</strong>: I tried that once in a case
  involving Pennsylvania, and the result was such that I
  resolved never to do it again.</p>
  
  <p>(Laughter.)</p>
  
  <p><strong>JUSTICE BREYER</strong>: But -- but don't say never.
  All right. So one thing we got --</p>
  
  <p><strong>JUSTICE ALITO</strong>: That was a case in which --
  that was the case in which the Court unwisely reversed a
  certain Third Circuit decision.</p>
