After the conviction of mayor
Eugene Schmitz on bribery charges in July 1907, Boxton was selected by Board of Supervisors to serve as mayor temporarily until a new mayor could be elected at a convention later that same month. One day after his election as mayor, Boxton was called as the first witness in the trial of Louis Glass, an executive with the Pacific States Telephone and Telegraph Company, from whom Boxton and 10 other supervisors had admitted taking bribes of $5,000 each. Boxton spent much of his week as a mayor shuttling between court and his official duties, and admitted – in addition to the bribery – to having lied under oath, signing a false affidavit in 1906. Boxton's tenure as mayor was marked by the additional confusion of former mayor Schmitz refusing to concede he had vacated the office, despite having been convicted and imprisoned for bribery. Insisting he would be exonerated upon appeal and reelected, Schmitz's supporters blockaded the mayor's office, forcing Boxton to relocate his offices. The convention called to replace Boxton quickly fell apart amid conflicts between business and labor interests. Subsequently, a trio of prosecutors involved in the Schmitz bribery case – including District Attorney
William H. Langdon – selected the next mayor,
Edward Robeson Taylor, a respected lawyer and physician then serving as dean of the
Hastings College of Law. Boxton subsequently resigned as mayor on July 16, allowing the Board of Supervisors to elect Taylor before resigning en masse themselves, thus allowing Taylor to appoint new supervisors. == Later life ==
