The state gave themselves an out against any lawsuit. Typically a suit asks for some type of relief, but since your ccl remains active as long as you've applied for renewal then there is no relief to be gained. A lawsuit is a no win situation.
In an unfortunate scenario, say a person is hurt and/or permanently injured in a self defense situation while under review 120+ days in (for a first time applicant/no carry). If they would have otherwise been armed, could the lawsuit be held on the grounds of their medical, pain and suffering, and future disability? Or worst case scenario, a person dies and family sues for wrongful death caused by the state over their denied right to self defense? It's a stretch but possible... I think.
