The right to contest a decision with consequences on individuals or the society is a well-established democratic right. Despite this right also being explicitly included in GDPR in reference to automated decision-making, its study seems to have received much less attention in the AI literature compared, for example, to the right to explanation.
Complementing the current attention on fairness, transparency, explainability and accountability for automated decision-making systems, in this talk we will focus on the right to contest decisions. We will discuss the type of assurances that are needed in a contesting process when algorithmic black boxes are involved, opening new questions about the interplay of contestability and explainability and proposing some ways forward.
