[T]o use a stay to accomplish indirectly what could not be done directly -- especially when it would cause certain irreparable harm to the defendants -- simply would be unjust. I hope and trust that the Government will have the good judgment, wisdom, and courage to avoid such a manifest injustice. To do otherwise, I fear, would undermine the faith in our system of justice of not only the defendants, but their millions of shareholders and the business community at large.
