  A paper presented at the Workshop on Contestability in Algorithmic Systems at
CSCW 2019. Challenging algorithmic decisions is important to decision subjects,
yet numerous factors can limit a person's ability to contest such decisions. We
propose that administrative law systems, which were created to ensure that
governments are kept accountable for their actions and decision making in
relation to individuals, can provide guidance on how to design contestation
systems for algorithmic decision-making.
