Chemerinsky brief argues Trump’s pardon of Arpaio is void

Erwin Chemerinsky, Michael Tigar, and Jane Tigar brief cited by ABA Journal, Sept. 12, 2017

The trio argue the pardon is void for three reasons. First, the brief argues the pardon is not authorized by Article II’s grant of pardon power for “offenses against the United States.” … Second, the amicus brief argues that the pardon violates the principle that Article III courts have a duty to provide effective redress when a public official violates the Constitution. Third, the brief argues that Article III courts have inherent power to enforce their orders “and this power exists outside and beyond legislative empowerment and executive whim.”
