A few months back i posted about a friend who got denied. He challenged his denial and received his response in approx. 2 months. His challenge was overturned and he was able to purchase the pistol he got denied on. The letter stated that they were able to resolve the issue for his denial and he is eligible to purchase/possess a firearm. My question which someone brought up to him was did this challenge "fix" the issue for denial or could he be denied on any future attempts to buy a firearm ? And have to go thru this process all over again. And yes he applied for a UPIN the letter also said they forwarded his VAF request to NICS for further processing.
