TULSA, Okla. (AP) — An attorney is challenging a state question that requires state communications to be in English.

James Thomas filed a civil lawsuit in Tulsa County District Court Tuesday against State Question 751, saying it's unconstitutional. The lawsuit names Delilah Gentges as the plaintiff and Gov. Brad Henry as the defendant.

State Rep. Randy Terrill (R-Moore) says the lawsuit to block the implementation of English as the official language of state government is another example of frivolous litigation by fringe groups.  The author of State Question 751 says more than 30 other states and 50 nations already have so-called “Official English” laws, and that learning English is “key to an immigrant’s success.”

State Question 751 requires all official state communications to be in English or Native American languages, except as otherwise required by federal law.

The Tulsa World reports that Thomas challenged SQ 751 in July, but the lawsuit was dismissed. He said he expected to file a new lawsuit after the election.

Thomas didn't immediately return a call seeking comment Tuesday.

On Monday, a federal judge temporarily blocked certification of the election results for a state question banning the use of Shariah law.
