Companion question to Questioner's liability for receiving a wrong psak.
Let's say that someone asks his Rav, for example, if a certain food is Kosher, and the Rav paskens that it is not, and that the food must be thrown out. Later on, the Rav realizes that he ruled incorrectly, and the questioner could, in fact, have eaten that food (or at least benefited from it).
Is the Rav responsible for damages, for having ruled incorrectly and causing the questioner to lose money as a result?
