Challenge to Pa. voter ID law is case of contradictions

Remind me again why this case is before the Pennsylvania Supreme Court.

From PA Independent:

All eight plaintiffs seeking an injunction to prevent the law from taking effect before the Nov. 6 election possess the required photo identification or other documentation the new law requires to vote. That brings to questions the plaintiff’s main claim that thousands of Pennsylvanians couldn’t obtain the necessary identification in time.
