R. Ovadia Yosef on Times We Do and Don't Immerse Utensils (6 Adar)

שו"ת יביע אומר יו"ד י:י 6 Adar 5763 (2003)

R. Ovadya Yosef writes to an author of a book on tevilat keilim, immersing utensils in the mikveh upon purchasing them from a non-Jew, to note that he had ruled in contrast to R. Yosef's own ruling. In the discussion, he elaborates when and whether we expand on decrees of Chazal, and what we do when faced with a davar she-yesh lo matirin, an item that is now prohibited but will become permissible.
