In the case of Avent v. United States in 1924, the Supreme Court ruled on an issue related to criminal law and procedure. The appellant, Avent, was convicted for violating a section of the National Prohibition Act by selling liquor without a prescription or medical purpose. He appealed his conviction arguing that there was insufficient evidence to support it and that he had been denied due process because certain evidence had been excluded at trial. However, the Supreme Court upheld his conviction stating that there was enough circumstantial evidence presented at trial to justify it and rejected his claim about being denied due process as they found no error in excluding certain pieces of evidence which were irrelevant or immaterial to proving guilt under prohibition laws.

In the dissenting opinion for Avent v. United States, it was argued that the majority's decision to uphold a conviction based on circumstantial evidence was flawed. The dissenting justices believed that there were significant doubts about whether or not the defendant had committed any crime at all, let alone one of such severity as murder. They pointed out inconsistencies in testimonies and lack of direct evidence linking the accused to the alleged crime scene or victim. Furthermore, they criticized how lower courts handled this case by allowing questionable evidences which could have led to an unfair trial process for Avent. They stressed that every individual is entitled to a fair trial with substantial proof beyond reasonable doubt before being convicted of any crime - a standard they felt wasn't met in this case.
