Halakhah for Meilah 10:9

From the laws of the commandment is that which they, may their memory be blessed, said (Zevachim 33b) that the impurity for which we are liable is when one is made impure by a Torah-level impurity, for which we are liable excision — the understanding is for approaching the Temple and its consecrated things, as we wrote above (Sefer HaChinukh 123). And that which they, may their memory be blessed, said (Zevachim 34a) that we are not liable for eating of the holy that has things that permit it, until those things that permit it have been brought — meaning to say its entrails. And likewise did they, may their memory be blessed, instruct us (Meilah 10a) that we are not liable on account of piggul or notar or on account of [being] impure, until those things that permit it have been properly brought. And [regarding] anything that does not have things that permit it, once it has been consecrated in a vessel, we are [potentially] liable for it. And the rest of its details are in the thirteenth chapter of Zevachim. (See Mishneh Torah, Laws of Sacrifices Rendered Unfit 18.)
