Debates over prison privatization neglect to consider differences in legal access across private and public prisons. I argue that private prisons experience lower filing rates than public prisons, and that cases brought against publicly traded private prison companies are less likely to be dismissed and more likely to succeed than similar cases against public prisons. I find evidence consistent with these claims, a result that is not driven by other explanations of judicial decision-making. This paper has implications for skepticism of private interests in public policymaking, and encourages investigation of access to justice for inmates in public and private custody.
