The U.S. Court of Appeals for the 5th Circuit took a second look at Texas’s strict voter-ID law to determine if it will be in effect for the November presidential election.

This is the second time this federal appeals court will review the state’s voter-ID law passed in 2011, however this time all 15 active judges on the court will weigh in.

Under the state law, Texans are required to show specific forms of voter identification in order to cast a ballot. This includes a U.S. passport, drivers license or concealed handgun license. Texas Republicans in support of the law argue that it prevents fraud.

Critics argue that the strict law makes it more difficult for minorities to vote, which they say is a violation of the Voting Rights Act.

“This Republican bill has made it harder a lot of minorities in Texas to vote,” Manny Garcia, Executive Director of the Texas Democratic Party said. “It’s been ruled discriminatory multiple times and yet it is still in effect right now.”

Garcia said if the law stays in place, 600,000 Texans will be deprived their right to vote in November and in any local election.

“There are over 600,000 Texans who are registered to vote in Texas, but at the time this law was passed, the legislature knew that these folks did not have the ID required to vote under the new law,” Garcia said. “Those folks are out in the cold right now while we are waiting for this decision to come down.”

In April, The United States Supreme Court declined to block the use of Texas’s voter-ID law in the November elections. The supreme court sent the case back to the Fifth Circuit and gave them a deadline of July 20 to make a decision.

If a decision is not made, the case will go back to the U.S Supreme Court, where only eight justices currently sit since the passing of Justice Antonin Scalia in February.

Alan Sager, professor at the University of Texas in Austin, said if this happens then there will likely be a tie vote, which means whatever the justices decide after Monday’s hearing will be the final say on Texas’s voter-ID law.

“I think the most likely outcome is that no matter how it turns out it is going to go back to the Supreme Court,” Sager said. “It all comes down to whether or not the court views this as a burden of any significance on your voting rights.”

Sager said the impact of the law won’t be felt in the November presidential election, rather in local congressional elections across the state. In these elections, depending on the make-up of the constituents, Sager said it could result in abnormally low voter turnout.

“You will see where it will really matter is in local elections,” Sager said, “where it could keep people from voting or keep people from fraudulent voting.”

The Texas Attorney General’s Office defended the Texas law before the U.S. Court of Appeals for the Fifth Circuit on Monday Morning.

“Safeguarding the integrity of our elections process is essential to preserving our democracy,” Texas Attorney General Ken Paxton said in a statement released Monday, “and our common-sense law provides simple protections to ensure our elections accurately reflect the will of the voters of Texas.”

Paxton testified earlier this year in Washington D.C. before the United States Supreme Court defending the law.
