If there was ever a no contact in place there was a reason and you should lust assume it will be in place forever.
is a no contact just a nicer way to say restraining order?
Probably depends on the jurisdiction. Where I'm at if it's a no contact order, then it's part of a sentence imposed upon conviction of a particular criminal offense or a condition of bond pending trial. If it's a restraining order, it's something one person goes to court and gets against another person without any involvement by a prosecutor. Private parties and a judge.
There isn't any scenario where something like SDK is describing would be within the authority of a prosecutor to remove or deactivate, only a judge. It's only done by court order. Maybe Kansas is different.
