The state courts of last resort are vital components of American judicial system, disposing of many important legal matters. The chief justices of these courts serve consequential roles in these institutions. Although scholars have examined the selection and duties of states' chief justices, their interactions with the elected branches are understudied. We focus on how chief justices on state high courts use their roles to encourage judicial reform. Specifically, we examine the determinants of chief justices' successes or failures as advocates for their justice systems. To analyze why chief justices succeed or fail as reform advocates, we analyze the fate of reform proposals offered in state of the judiciary addresses. Our results indicate that greater ideological similarity between the state legislature and chief justice or state supreme court median increases the odds of an agenda item being enacted. We also find that the scope of a policy request influences the likelihood it will be granted.
