What law was enacted to establish civil service rules and prevent nepotism in government?

The Pendleton Act was enacted in 1883 to reform the federal hiring process and establish civil service rules. It aimed to eliminate the patronage system where government jobs were awarded based on political connections rather than merit. This legislation was a significant step toward professionalizing the civil service, ensuring that jobs were filled through competitive examinations and established qualifications.

By implementing these civil service rules, the Pendleton Act also worked to prevent nepotism and favoritism in government hiring practices. It laid the groundwork for a merit-based system that focused on the abilities and qualifications of candidates rather than their personal or political relationships. As a result, the Pendleton Act significantly affected how government employees were hired and managed, creating a more equitable and effective public service.

The other options refer to different laws or concepts that do not directly relate to civil service rules or nepotism in government. The Tennyson Act pertains to specific funding and support during the Civil War, the Garrity Act relates to the rights of public employees, and the Exclusionary Rule is a legal principle in criminal law, focusing on evidence obtained unlawfully. Therefore, the Pendleton Act is the most relevant and correct choice regarding the establishment of civil service rules and the prevention of nepotism in government.
