Too many people with disabilities (including people with intellectual and developmental disabilities), are harmed in family, community, and workplace settings, and in the course of using the formal services intended to support and empower (CRE-DH (Centre of Research Excellence in Disability and Health), 2021; Dowse et al., 2013). As Hough (2021) reminded us, in Australia as in the United Kingdom and elsewhere, such harms have been popularly framed as individual incidents or "scandals," the most serious of which have triggered official inquiries, together generating hundreds of recommendations for change. Hough (2021) has made way for an expanded focus, turning attention from these individual occurrences of harm in disability service settings, to examine the ways regulatory arrangements are designed to prevent and address harm across the service system.Hough (2021) has a strong case for drawing on the underutilised tools of regulation theory to examine the quality and safeguarding arrangements that operate within Australia's National Disability Insurance Scheme (NDIS). While key regulatory concepts, such as "gaming," "ritualism," and "responsive regulation" were developed in the context of Australian aged care research (Braithwaite et al., 2007), regulatory theory appears to have had surprisingly little use in informing new arrangements in disability services. Hough (2021) has demonstrated how general literature on regulation theory offers a helpful basis for understanding the structure and operation of regulatory arrangements under the NDIS.To do this, he has drawn on regulatory theorists such as Ayres and Braithwaite (1992) and Baldwin et al. (2012), to identify and situate the formal regulatory mechanisms of the NDIS, examine their role, and set some conceptual foundations for assessing the adequacy of NDIS regulation for preventing and addressing harm. The work provides an unsettling reminder of the ways the formal regulatory architecture now in place was developed, not out of careful theorisation or evaluation of evidence, but rather from a series of inherently political design choices and trade-offs. By demonstrating opportunities for connection across otherwise disconnected bodies of thinking,
