הלכה על פסחים 5:6

From the laws of the commandment is that which they, may their memory be blessed, said (Pesachim 82b) that included in notar and piggul are all disqualified [sacrifices], such that all of them are also burned. And a sacrifice that is definitely disqualified or made piggul is burned immediately. But if there is a doubt, its form is left to be altered, and it is burnt afterwards (Mishneh Torah, Laws of Sacrifices Rendered Unfit 19:2). And any meat that is found in the [Temple] yard as limbs is burnt-offerings - the understanding of which is that we treat them like burnt-offerings; and if it is found as pieces, they are sin-offerings; and that which is found in Jerusalem is a peace-offering (Mishnah Shekalim 7:2). And the difference that comes out of this is if one transgressed and ate from them, he brings his atonement according to this assumption. But they, may their memory be blessed, said about all [of them], "Let their form be altered and [then] go out to the House of Burning, lest [they were] notar." And we only burn notar during the day, as it is stated, "on the third day, it shall be brunt with fire" (Pesachim 3a). And even though the peace-offerings are forbidden to eat from the beginning of the second night, we only burn them during the day. And the rest of its details are elucidated in Pesachim and at the end of Terumah (see Mishneh Torah, Laws of Sacrifices Rendered Unfit 19).
