Has the Justice Department ever issued an order to dismiss charges that was not based on the facts of a case or the law?

According to former Manhattan District Attorney Cyrus Vance Jr., he cannot recall such an instance. He states this situation is highly unusual with uncertain precedent. While there have been historical instances of presidential executive interference with Justice Department actions (such as the Saturday Night Massacre), where government lawyers have sometimes refused to comply with orders, nothing matches the exact circumstances of this case involving Mayor Adams. Vance notes that while there may be some analogous situations in American legal history, the current dismissal of corruption charges against Mayor Eric Adams represents an extraordinary and unprecedented action by the Justice Department.
