Crimmins appealed on the grounds that he did not know the bonds had been transported across state lines.

He reasoned that a jury may have found Crimmins guilty of the substantive offense of using interstate commerce in the commission of a crime because he knowingly bought stolen bonds even if he didn't know where they were from, but that "It is never permissible to enlarge the scope of the conspiracy itself by proving that some of the conspirators, unknown to the rest, have done what was beyond the reasonable intendment of the common understanding".

[1] According to Hand, people can only be charged for the actions of co-conspirators that were mutually agreed upon.
