Requires notice be provided upon changes to voter registration; prohibits changes in party affiliation from being processed after statutory deadline.

This bill requires New Jersey election officials to notify voters within five business days if their request to change political party affiliation isn't processed due to missing the statutory deadline for primary elections. It prohibits updating party affiliation after the deadline (55 days before a primary), ensuring voters remain affiliated with their previous party until the primary election concludes. Voters denied voting in their preferred primary due to outdated registration can cast a provisional ballot and seek judicial review; if confirmed they met the deadline, the ballot is counted. The bill directly affects voters attempting to switch parties late and election officials processing registration forms.
