Nathan O. Murphy v. James L. Utter was a legal case that involved a petition for a writ of mandamus to compel the Loan Commissioners to issue refunding bonds in exchange for those originally issued by the County of Pima in aid. The case was initially heard under the name of Utter v. Franklin and the order of the supreme court of Arizona denying a writ of mandamus was reversed and the case remanded for further proceedings. However, the entire issue was later declared to be void by the court in Lewis v. Pima County. The case was then cited in several other opinions and decisions, including United States v. Murphy, which involved a conviction for distribution and possession with the intent to distribute heroin and cocaine base.
