In the case of United States v. Weissman et al., 1924, the Supreme Court dealt with issues related to conspiracy and fraud against the government. The defendants were charged with conspiring to defraud the United States by obtaining money from it under false pretenses. They had allegedly made fraudulent claims for reimbursement for medical services provided to draft inductees during World War I, which they never actually rendered. The defense argued that since no actual loss was incurred by the government (as no payments were made), there could be no conviction for conspiracy to defraud. The Supreme Court disagreed and upheld their convictions, ruling that a scheme intended to defraud did not need result in an actual financial loss or damage for it to constitute a crime; intent itself was sufficient grounds for prosecution and conviction under federal law.

The dissenting opinion in the United States v. Weissman et al., 1924 case is not readily available or may not exist. The details of this specific case are scarce and it's difficult to find comprehensive information about it, including any dissenting opinions that might have been expressed by the justices involved. It's possible that all justices agreed on the decision, hence no dissenting opinion was written. Alternatively, if there were disagreements among them, those views weren't officially recorded or they haven't been preserved and made accessible for public review today.
