The emergence of networks made up by both public and private entities governing sensitive decisions about the allocation of public services requires a deep rethinking of the traditional notions of public accountability. This study’s assumption is that in the era of algorithmic administrative decision-making governments’ accountability is intrinsically connected to the transparency of companies’ processing activities. The first section highlights the legal impediments to the achievement of accountability of government’s algorithmic-driven decision-making. The second section focuses on the new transparency tools entailed in the General Data Protection Regulation. The paper proposes an integrated approach between traditional administrative law tools and business-centred provisions entailed in the GDPR. Such an approach is essential for an effective protection of citizens’ fundamental rights that a short-sighted conception of public accountability would undermine.
