Petitioner, Hans Max Haupt was indicted for treason, convicted and sentenced to life imprisonment and to pay a fine of $10,000. From this judgment of the District Court for the Northern District of Illinois he appealed to the United States Circuit Court of Appeals for the Seventh Circuit, which by a divided court affirmed. 152 F.2d 771. A previous conviction of the same offense predicated on the same acts had been reversed. United States v. Haupt, 7 Cir., 136 F.2d 661.

Petitioner is the father of Herber Haupt, one of the eight saboteurs convicted by a military tribunal. See Ex parte Quirin, 317 U.S. 1, 63 S.Ct. 1, 2, 87 L.Ed. 3. Sheltering his son, assisting him in getting a job, and in acquiring an automobile, all alleged to be with knowledge of the son's mission, involved defendant in the treason charge.

Haupt v. United States (330 U.S. 631)/Opinion of the Court

The background facts are not in dispute. The defendant is a naturalized citizen, born in Germany. He came to this country in 1923 and lived in or near Chicago. In 1939 the son, Herbert, who had also been born in Germany, worked for the Simpson Optical Company in Chicago which manufactured lenses for instruments, including parts for the Norden bomb sight. In the spring of 1941 Herbert went to Mexico and, with the aid of the German Consul, from there to Japan and thence to Germany where he entered the employ of the German Government and was trained in sabotage work.

Haupt v. United States (330 U.S. 631)/Opinion of the Court

On the 17th of June 1942, Herbert returned to the United States by submarine. His mission was to act as a secret agent, spy and saboteur for the German Reich. He was instructed to proceed to Chicago, to procure an automobile for the use of himself and his confederates in their work of sabotage and espionage, to obtain reemployment with the Simpson Optical Company where he was to gather information, particularly as to the vital parts and bottlenecks of the plant, to be communicated to his coconspirators to guide their attack. He came with various other instructions, equipped with large sums of money, and went to Chicago.

Haupt v. United States (330 U.S. 631)/Opinion of the Court

After some six days there, Herbert was arrested on June 27, 1942, having been under surveillance by Government agents during his entire stay in Chicago. This petitioner was thereafter taken into custody and was arraigned on July 21, 1942. He later asked to talk to an F.B.I. agent, two of whom were summoned, and he appears to have volunteered considerable information and to have given more in answer to their questions. He blamed certain others for the predicament of his son and wanted to testify against them. For this purpose, he disclosed that he had been present when Herbert had told the complete story of his trip to Mexico, Japan, his return to the United States by submarine, and his bringing large sums of money with him. During his confinement in the Cook County jail he also talked with two fellow prisoners concerning his case and they testified as to damaging admissions made to them.

The indictment alleged twenty-nine overt acts of treason. Its sufficiency ws challenged by demurrer which was overruled and by a motion to quash which was denied. The defendant, at the close of the Government's case and again at the close of all the evidence, made motions for a directed verdict generally and also specifically as to each overt act charged, all of which were denied. Seventeen of the overt acts were withdrawn before submission and twelve were submitted to the jury. Generally stated, the overt acts submitted fall into three groups of charges: First, the charge that this defendant accompanied his son to assist him in obtaining employment in a plant engaged in manufacturing the Norden bomb sight; second, the charge of harboring and sheltering Herbert Haupt; and third, the charge of accompanying Herbert to an automobile sales agency, arranging, making payment for and purchasing an automobile for Herbert. Each of these was alleged to be in aid of Herbert's known purpose of sabotage.

The defendant argues here that the overt acts submitted do not constitute acts of treason, but that each is commonplace, insignificant and colorless, and not sufficient even if properly proved to support a conviction. We have held that the minimum function of the overt act in a treason prosecution is that it show action by the accused which really was aid and comfort to the enemy. Cramer v. United States, 325 U.S. 1, 34, 65 S.Ct. 918, 934, 89 L.Ed. 1441. This is a separate inquiry from that as to whether the acts were done because of adherence to the enemy, for cts helpful to the enemy may nevertheless be innocent of treasonable character.
