[Avodah] The Kiddushin "raid" in Lakewood

[arnold.lustiger at exxonmobil.com]

About a month ago, a Lakewood bochur got married. Before the wedding, he
had given the ring to his sister for safekeeping, who then returmed it to
him to perform the actual kiddushin. A few days later, in the middle of the
week of sheva brachos, the sister discovered that she had mistakenly given
her brother her own wedding ring, not the one that  he had originally given
to her. This discovery was made during just prior to Shabbos Sheva Brachos.
The question is: do the sheva brachos go on as scheduled?

They are learning Kiddushin this zman in Lakewood, and the story, while
obviously painful and embarrassing to the family, offered an opportunity
for thousands of guys to discuss the halachic ramifications:

1) Does the sister have ne'emanus? If not, is it not a case of shavya
anafshei?
2) Kiddushin on Shabbos is an issur derabanan. Would this issur be
suspended in this case so a private reenactment of the Kiddushin would be
allowed totake place on Shabbos itself, thus avoiding sheva brachos
levatalah?
3)  Can there be a chalos of nisuin without eirusin, allowing the sheva
brachos to continue even without this reenactment? The famous Mordechai
comes to mind that chuppah is really the badekin, which places the nisuin
before the eirusin.

Lema'aseh, the psak was that the sheva brachos could continue, but that the
eirusin would have to be redone privately on Motzei Shabbos.
