In the case of United States v. Minnie Atkins et al., 1922, the Supreme Court dealt with issues related to mail fraud and conspiracy. The defendants, including Minnie Atkins, were charged with using the U.S. Postal Service for fraudulent purposes by sending out deceptive materials designed to defraud individuals of their money or property through a scheme known as "The Circle." This involved soliciting funds from victims under false pretenses that they would receive substantial returns on their investments when in fact no such returns existed. The court held that this constituted a violation of federal law prohibiting mail fraud and upheld the convictions against all defendants.

The dissenting opinion in the case of United States v. Minnie Atkins et al., 1922, is not readily available from public sources. This could be due to a variety of reasons such as the age of the case, lack of digitization or simply because there was no recorded dissenting opinion for this particular Supreme Court decision. It's also possible that all justices concurred with the majority ruling and thus no dissent was written. Further research would be required using legal databases or archives to determine if a dissenting opinion exists for this specific court case.
