Revises processing of valid mail-in ballots received after closure of polls.

This bill revises how New Jersey county election boards handle valid mail-in ballots received after polls close but within specific timeframes. It specifies that ballots with a pre-election postmark received within 144 hours (6 days) of poll closure, or those delivered by USPS within 48 hours after closure, are valid and must be processed. County boards must number and have both a Republican and Democrat representative initial these ballots on receipt, then keep them sealed in their inner envelopes for 60 days before canvassing. Only a Superior Court judge may access these ballots during that period for legal proceedings, ensuring security and preventing premature disclosure of results. This affects all county election officials managing mail-in ballots after election day.
