Although the People with Disabilities Rights Protection Act stipulates the government’s responsibility to enact early retirement measures for people with disabilities, this policy remains unimplemented despite active civic group initiatives in Taiwan. Drawing on the ideational institutionalist perspective, we analyze the policymaking processes leading to this outcome. Based on the analysis of data from semi-structured interviews conducted with government officials, policy experts, and advocacy groups, significant divergences exist among the key actors regarding the definition of “equality” as a normative value. Furthermore, despite a consensus on invalidity pension reform, workplace support, and reasonable accommodation, government officials and policy experts gained the upper hand in the ideational contestation, reframing policy discourse to question the necessity of early retirement. Policy discussion has marginalized advocacy groups advocating for this policy, leading to the failure of policy implementation.
