John Marshall Harlan II,
United States v. Shotwell Manufacturing Company…
“ Their objection that it is 'unfair' to allow the Government at this stage of the proceedings to 'bolster' the record relating to the suppression issue is likewise unacceptable. It is undeniable, of course, that upon appellate reversal of a conviction the Government is not limited at a new trial to the evidence presented at the first trial, but is free to strengthen its case in any way it can by the introduction of new evidence. We think that in the peculiar circumstances of this case the fair administration of justice requires that the Government should have a similar opportunity here. ”
