I picked up this in yesterday's Washington Post: Robert Barnes, Supreme Court to consider case that could affect potential Manafort prosecutions (WAPO 12/2/18), here. The opening is )bold face supplied by JAT):
The Supreme Court next week takes up the case of a small-time Alabama felon, Terance Gamble, who complains that his convictions by state and federal prosecutors for the same gun possession crime violate constitutional protections against double jeopardy.
But likely to be watching the proceedings closely will be those concerned about a big-time felon, Republican consultant and former Trump campaign chairman Paul Manafort, who was prosecuted by special counsel Robert S. Mueller III for tax fraud.
With President Trump keeping alive prospects that he might pardon Manafort, Gamble v. United States might be redubbed Manafort v. Mueller, joked Thomas C. Goldstein, an attorney who regularly argues before the Supreme Court.
The outcome in the case could affect nascent plans by states to prosecute Manafort under their own tax evasion laws — New York, in particular, has expressed interest — should Trump pardon Manafort on his federal convictions.
The double jeopardy clause of the Constitution’s Fifth Amendment prohibits more than one prosecution or punishment for the same offense. But the Supreme Court since the 1850s has made an exception, allowing successive prosecutions and punishments if one is brought by state prosecutors and the other by the federal government. (One early case from that time involved counterfeiting; another was prosecution of someone harboring a fugitive slave.)
In Gamble, the court is reconsidering these precedents. Almost none of the briefs filed in the case speculate on how a presidential pardon of a federal conviction would affect prosecutors at the state level should the so-called separate sovereigns doctrine be renounced.
