(KCEN) -- Pennsylvania's voter ID law is now in the hands of the state's Supreme Court.
The legislation requires that voters have a current, government issued photo ID to cast their vote at the polls.
An attorney representing voters in the case says the law puts an unconstitutional burden on people's right to vote.
In July, the Pennsylvania Department of State estimated that 758,000 registered voters did not have the correct form of ID.
A similar law was passed in Texas, but was later overturned.
