Conditions for Bayesian posterior robustness have been examined in recent literature. However, many of the proofs seem to be long and complicated. In this paper, we first summarize some basic lemmas that have been applied implicitly or explicitly. Then, using them, we give a simple proof of posterior robustness. Our sufficient condition is new and practically relevant.
