The New Jersey Supreme Court has reinstated a ban on exit polls, surveys taken of people as they leave their voting places.

It also has kept in place a ban on distributing leaflets or other materials within 100 feet of polling places. It said Wednesday prohibiting such activities will ensure voters feel no obstructions to casting their ballots.

The ban on approaching voters was created in 1972. It was changed in 2007 by the state attorney general to allow for exit polling by journalists.

The state branch of the American Civil Liberties Union argued it also should be allowed to approach voters so it could give them cards explaining their rights and telling them how to report problems.

But the state said if the ACLU were allowed past the 100-foot border, other groups would be permitted also.
