In the case of Wheeldin et al. v. Wheeler, 1962, the U.S Supreme Court ruled in favor of petitioner Wheeldin who had been subpoenaed by a federal grand jury and later sued respondent Wheeler for false arrest and imprisonment. The court held that there was no statutory or inherent power vested in a United States Commissioner to issue subpoenas to bring witnesses before a federal grand jury; thus making his actions unauthorized under Federal law. Furthermore, it was determined that even if such authority existed, it would not provide immunity from civil damages for wrongful issuance of process since this is not an integral part of judicial function but rather an administrative one. This decision clarified limitations on powers granted to government officials and emphasized their accountability for misuse or overstepping boundaries.

In the dissenting opinion for Wheeldin v. Wheeler, Justice Douglas argued that federal officers should be held accountable for their actions and not given absolute immunity from prosecution. He believed that if a federal officer violates an individual's constitutional rights, they should be liable to answer in court just like any other citizen would be. This includes instances where the officer is acting outside of his jurisdiction or abusing his power. Justice Douglas also pointed out that there are already legal mechanisms in place to protect officers who are acting within their authority and following proper procedures; therefore, granting them complete immunity is unnecessary and unjustifiable. He concluded by stating that no one should be above the law - including those tasked with enforcing it.
