This statement makes no sense - since you say one go to MA court to appeal a restriction but you can appeal in civil court - which logically would mean that civil court is not a MA court.
The appeal is to MA District Court. The law states that a "denial" may be appealed, but is silent as to whether a "restriction" is a denial. I know it is possible to appeal, as I have read a decision on one such appeal. Although the appellant lost, the court wrote a lengthy opinion as to why it favors a dedicated LE professional over a plebeian. If an appeal were "not allowed", the decision would have simply been to deny standing.
The problem is that the first thing the LE is going to say is "Your honor, I don't understand why were are here since I issued an LTC". The judge will then ask the appellant "is that true" and, if the judge is predisposed to deny will respond with "dismissed, next case please" why you are standing there going "but, but...." and told to move on.
Sorry, it should say "MA District Court" and I should have been clearer with regard to Civil Court vs District Court. Rob is 100% correct and better at explaining it than I. Thanks for the follow up Rob.
