Versatile character actor Don Anderson has three separate appearances in this episode: as an attorney, an ambulance attendant, and a courtroom spectator.
In the opening scene, Judge Redmond and Perry are discussing the case he lost and they mention two older cases, Jones v Hart (1698) and Priestly v Fowler (1837). Both are actual cases from English tort law and dealt with an employer not being liable for injuries sustained by one employee when caused by another employee in the course of their employment.
Last episode to be edited by John Faure (as John D. Faure), who died in early July 1963, just a few months after it first aired. In all, Faure edited more than 50 Perry Mason episodes; he was nominated for an Emmy for this work (in 1961).
Perry Mason did lose one case during the series. During the very beginning scene in a courtroom in this episode, the judge and Perry Mason are discussing Perry Mason's losing a case by arguing bad law. The judge suggested Perry take it to a higher court, but Perry told the judge it wouldn't be worth it since the judge's decisions hadn't been overturned in 20 years.
Judge Daniel Redmond, the defendant in this episode, may have been inspired by Goodwin Knight, governor of California from 1953 to 1959. Like Redmond, Knight was a judge who entered politics and ran for lieutenant governor of California. In real life, Knight won and then became Governor when sitting Governor Earl Warren was appointed Chief Justice of the U. S. Supreme Court.
