We analyze different notions of fairness in decision making when the underlying model is not known with certainty. We argue that recent notions of fairness in machine learning need to be modified to incorporate uncertainties about model parameters. We introduce the notion of {\em subjective fairness} as a suitable candidate for fair Bayesian decision making rules, relate this definition with existing ones, and experimentally demonstrate the inherent accuracy-fairness tradeoff under this definition.
