“The Utah lawmaker Orrin Hatch, who sits on the Senate Judiciary Committee, filed a 44-page amicus brief earlier this month in Gamble v. United States, a case that will consider whether the dual-sovereignty doctrine should be put to rest. The 150-year-old exception to the Fifth Amendment’s double-jeopardy clause allows state and federal courts to prosecute the same person for the same criminal offense. According to the brief he filed on September 11, Hatch believes the doctrine should be overturned.”
“Within the context of the Mueller probe, legal observers have seen the dual-sovereignty doctrine as a check on President Donald Trump’s power: It could discourage him from trying to shut down the Mueller investigation or pardon anyone caught up in the probe, because the pardon wouldn’t be applied to state charges. ”
