Recently, the Arizona Supreme Court issued a written opinion in an Arizona homicide case discussing whether the defendant’s conviction for murder was invalid based on a double-jeopardy violation. The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution provides that “nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb.” While the language used in the clause is somewhat archaic, this case illustrates that the principles behind the clause are as essential today as they ever were.
According to the court’s opinion, the defendant was tried for murder in 2013, after he shot his neighbor. Evidently, the neighbor approached the defendant after the defendant asked him to leave. The defendant testified that he believed the neighbor was armed.
After the parties presented their cases, the jury could not agree on whether the defendant was guilty of first-degree murder, marking the box “unable to agree” next to the first-degree murder charge. The jury found the defendant guilty of second-degree murder, and the court sentenced him to 16 years incarceration. An appellate court later reversed the conviction based on procedural grounds, remanding the case for a new trial.
