These are state and federal laws, if there is a ppo he is considered a violent person with a high risk of commiting a violent crime. (IANAL, just good at using google to learn about my rights).
He needs to get an attorney, he needs to find out the details of the PPO (it should have been mailed to him), as it is a PPO he should be made aware of who brought it against him, who he can't see/be near, and why.
It could be a mix up because his name is similar to someone elses.
But he needs to get an attorney and begin to fight this immediately.
If he did do something to get this PPO issued against him (it is harder than hell to get a PPO for most people legitimately seeking them, so I would assume this is mistaken identity or there is something you don't know), he needs to get in front of the court and find out why and how to fix it.
See the below text....
In order for your PPO to qualify under Federal law, the defendant (person who the order is against) must:
•Be served (given) notice of the court hearing. In other words, the defendant must have been given paperwork that told him or her about the hearing.
•Have an opportunity to attend the court hearing.
Note: The abuser does not have to be at the hearing, but s/he has to have the opportunity to come to the hearing.
•Be an "intimate partner" of the victim, which includes: ◦A current or former spouse
◦A person with whom you share a child
◦A person you live with or have lived with in the past**
Note: If your PPO has expired, it is no longer a valid order under Federal law, which means the firearm ban also does not apply. The expiration date must be stated clearly on the order and should be written in item #8 at the bottom of the first page of your PPO.***
Note: This law may not apply to law enforcement officials, military personnel, and other government employees who use guns while performing official duties.**** If your abuser is a police officer, member of the military, or someone else who uses a gun for their job, talk to your local domestic violence program about your options.
