As a reform movement and an academic discipline, American public administrationgenerally coalesced during the Progressive era (1890-1920). Progressive reforms for the public sector seeped deeply into the DNA of the field, including separation of civil servants from politics, reliance on expertise, fewer elected offices, and public reporting of agency activities. However, not all of the governmental reforms proposed during this era were enacted. One of the most controversial and least known was Theodore Roosevelt’s proposal in 1912 that the voters be able to have a referendum on major court decisions, permitting them to overturn those decisions. His idea was only enacted in Colorado, where it remained on the books until 1921. This article reviews the original concept and its history in Colorado.
