With no explanation, chose the best option from "A", "B", "C" or "D". holds the delicate balance between sometimes conflicting rights steady and true. This approach is also scrupulously fair. To punish providers when they satisfy an objective standard based on the best evidence available at the time of their decisions would be to punish them for a lack of clairvoyance. By the same token, to hold providers harmless after they have refused treatment based on nothing more than unfounded trepidation would run at cross-purposes with the central theme of the ADA. Fundamental fairness insists that providers in such circumstances ought not to be entitled to rely on subsequent understandings to shield them from the condign consequences of discriminatory conduct.
