According to KOCO, a judge will hear arguments on Wednesday on whether a temporary injunction should be put on Oklahoma's permitless carry law.
The law will allow people to carry a gun without a permit or any training.
Rep. Jason Lowe filed a lawsuit saying the bill is unconstitutional because it violates a rule that laws have to be about one topic.
Gov. Kevin Stitt said an injunction would, "undermine the fundamental right to keep and bear arms,” as a response to the challenge.
If the judge does not grant an injunction, the law will go into effect Friday.
