HARRISBURG — Pennsylvania voters will not be required to show photo identification in the May 21 primary election under an agreement signed Thursday by both sides in a pending lawsuit.

Lawyers representing the Corbett administration and plaintiffs who are challenging the constitutionality of the voter ID law in state Commonwealth Court agreed the law won’t be enforced as voters choose nominees for judicial and municipal offices.

Local election officials can ask to see identification, as they did in the presidential election last fall, but voters will be allowed to cast ballots as usual even if they lack those documents.

“At this point, we just don’t see the (need) to litigate the issue,” said Senior Deputy Attorney General Patrick S. Cawley, who represents the administration.
