Thank you for your question.
Federal law prevents ownership
of a firearm by a person who has been involuntarily committed to a mental institution. Arkansas in my opinion has gone too far in denying a CCW permit to anyone who ever went in voluntarily. Such a law discourages people who need help from seeking it, and unfairly stigmatizes anyone who ever sought treatment voluntarily at that type of facility. So, in my opinion, the law is probably unconstitutional as overly broad.
Furthermore, people voluntarily enter and leave mental health facilities every day and it is no one else's business. It sounds like the State is demanding a waiver of your medical privacy rights to even apply for a CCW. An involuntary commitment results in a public record, but not voluntary treatment.
I urge you to consult a local civil rights
lawyer about how to best approach this problem. You can get a free consultation from some of the civil rights attorneys listed by location here
Prevailing civil rights plaintiffs are routinely awarded attorney fees, so please do not hesitate to contact a lawyer out of fear that it will cost a lot of money.
I hope this information is helpful.
