For those following daf yomi, the basis for this one came up recently. If a person steals chometz, pesach comes and goes, rendering this chometz she’ovar olov hapesach, he can give it back and say “harai shelcha lefonecha” because there was no shinui be’ein…hezek she’aino nikar. If the ganiv sold it with his chometz, what’s wrong? There should be no problem with this chometz? If you hold shinui is koneh let the ganiv sell it with his chometz, if not, the nignav had it sold with his chometz? Perhaps we can answer that there is still a problem because the ganiv may have a problem selling it because he may be chayev daled vehay. So you’ll tell me, daled vehay is only by shor and seh, there’s another reason, the goy may not want to be koneh chometz that could be problematic and this chometz bleibs by the ganiv.
Disclaimer: I’m not really such a tipish. This is something based on false premise, but since I found it a bit amusing in it’s lumdis based on false premise, I wanted to share.
