In the case of Childers v. McClaghry, 1909, the U.S Supreme Court was asked to consider whether a prisoner could be punished twice for the same crime under different jurisdictions - federal and state. The petitioner, Childers, had been convicted in both Kansas State court and Federal court for counterfeiting coins. He argued that this constituted double jeopardy as prohibited by the Fifth Amendment of the Constitution. However, his argument was rejected by Justice Moody who delivered an unanimous opinion on behalf of all nine justices stating that separate sovereigns (in this case state and federal governments) can each prosecute an individual without violating their constitutional rights against double jeopardy because they are distinct entities with their own laws to enforce.

In the dissenting opinion for Childers v. McClaughry, it was argued that the petitioner's constitutional rights were violated due to a lack of fair trial. The dissent focused on two main points: first, that the court had erred in allowing evidence obtained through an unlawful search and seizure; secondly, that there was a violation of due process because the defendant did not have competent legal representation during his trial. It was contended that these errors significantly impacted the outcome of the case and thus warranted reversal or at least reconsideration by a lower court. This view emphasized strict adherence to constitutional protections as paramount over procedural technicalities or expediency in criminal proceedings.
