[1] As a federal prosecutor, he helped convict Al Capone of tax evasion and challenged the city's political leaders and their system of influence.

[3][4]The defendants in this case stand convicted of the crime of treason and it now becomes the solemn duty of the Court to fix punishment and impose sentence.

Where offenders stand convicted of serious crimes against the United States, it is customary for the Court, in pronouncing sentence, to recapitulate rather fully the testimony offered during the trial.

Here, an able, considerate and patient jury of men and women from every walk of life, representative of the finest ideals of our American commonwealth was carefully chosen by both sides.

The five days preceding the argument on the motion for a new trial were devoted exclusively by the Court to a careful and exhaustive review of this abstract and of the transcript of the testimony herein.

In pronouncing sentence upon these six men and women, this Court is constrained to give full consideration to the fact that our nation, and every man, woman and child in it, are engaged in a global death struggle against forces of tyranny and evil unprecedented in the history of mankind.

Deliberately and in secret, under the cloak of American citizenship, the agents and helpers of the saboteur scheme and connive to destroy their neighbors and this nation.

Likewise the sentence must serve notice upon the enemy that the cunningly devised scheme for the use of American citizens of German birth as pawns in the game of sabotage and espionage in this Country is doomed to failure.

Citizens threatened with the torture of their relatives in Germany for failure to assist German agents in this Country must be impressed with the personal danger involved in yielding to such contemptible coercion.

It was apparent on the trial of this cause that each of the woman defendants, though knowing  the seriousness and evil nature of her actions, undoubtedly followed the leadership of her husband.

It is, therefore, the judgment of this Court upon the verdict of the jury heretofore returned that the defendants Hans Max Haupt, Erna Emma Haupt, Walter Otto Froehling, Lucille Froehling, Otto Richard Wergin and Kate Martha Wergin, and each of them, are guilty of the crime of treason as charged in the indictment in this cause.

The defendants Erna Emma Haupt, Lucille Froehling and Kate Martha Wergin, and each of them, are sentenced to the custody of the Attorney General to be imprisoned in a penitentiary for a term of twenty-five years and each of them to pay a fine of ten thousand dollars.

In 1957, Hans Haupt was granted clemency by President Dwight D. Eisenhower and deported to Germany on the condition that he would never return to the United States.

"[citation needed] Although Campbell is regarded as a forefather in the state of today's justice system, he has been criticized by some prominent investigative persons for his actions.

The investigative journalist Jonathan Kwitny later argued that the case was "A fine example of what can happen when important matters of public policy are abandoned by government to the self-interest of corporations."
