No but they are similar enough that I’d think it would take some mental gymnastics to rule differently on how they are handled. I would also think that unless the legislature passed an emergency mail in ballot law that just sending unsolicited ballots to addresses with no knowledge of who actually lives there and the ultimate disposition of such ballots would be cause for judicial concern.
They’re not similar at all — not in NJ, at least. Absentee ballots must be requested ahead of time, positive identification must be provided to get one, and they are required to be returned within defined time frames. The mail-in ballots were sent out in mass mailing, did not need to be requested, no mechanism was provided for verifying identity, and some states illegally altered deadlines for when they could be returned.
