(CNN) - A coalition of Pennsylvania civil rights groups filed an appeal Thursday to overturn a judge's ruling that upheld a controversial voter identification law.
The appeal seeks to prevent the law, which requires voters to present a state issued photo ID, from being enforced in November's election, said American Civil Liberties Union of Pennsylvania associate director Sara Mullen.

The law, upheld last week, has been met with fierce opposition by those who claim it discriminates against minorities who may not have proper identification. Proponents of the law, however, argue it helps to fight fraud at the voting booth.
One plaintiff in the case, Viviette Applewhite, was granted a state issued photo ID on Thursday, which will allow her to vote in the upcoming election, Mullen said.
The 93-year-old told CNN she was concerned she would not be able to vote after losing her social security card and birth certificate when her purse was stolen. She was initially unable to obtain a state issued identification card because of the paperwork required by the Pennsylvania Department of Transportation.
"We're very happy for her," Mullen said. "(But) it doesn't really change the case. It's about the hundreds of people who don't have IDs."
Commonwealth Court of Pennsylvania Judge Robert Simpson issued an order on Wednesday saying there was no constitutional reason to stop the law from taking effect. In his opinion, however, he wrote that he had "sympathy" for the witnesses.
The coalition, however, seeks to appeal the law in the State Supreme Court, requesting that the court hear the case on an expedited basis because the election is less than three months away.
The ACLU of Pennsylvania, the Public Interest Law Center of Philadelphia, the Advancement Project and the law firm of Arnold & Porter filed the appeal jointly.
"The fight in this case could go on after the election. Judge Simpson's ruling was on the request for a preliminary injunction. There could still be a hearing for a final injunction," said the ACLU of Pennsylvania in a statement.
The Pennsylvania Supreme Court was not immediately available to comment on the appeal.
In Pennsylvania, support for the law has largely been divided along party lines. Republicans argue the new law helps to fight fraud, while Democrats make the case that the new law aids Republicans in the voting booth by limiting turnout by minorities in the crucial battleground state.
Pennsylvania represents a crucial battleground state this fall in the presidential election. While a Republican candidate hasn't won the state since 1988 – Barack Obama won Pennsylvania by 10 points in 2008 - the GOP has made big gains in recent years and the state has a Republican governor and one U.S. senator.
