Without question, petty neighborhood squabbles are clogging up very busy court dockets. It is time for a loser pays systems where losers of petty complaints are required to pay the costs incurred while bringing these baseless claims to court. Too many Real claims are being laid to waste because of this.
Some neighbor "squabbles" are the result of busybody complaints, but others really do legitimately deserve to be heard in court. If your neighbor's actions are impacting your ability to sleep or enjoy your living space. Your neighbor has a right to privacy, and to enjoy some reasonable activities, ie. auto repair, gardening etc, as long as they aren't overly intrusive.
No, neighborhood squabbles are not clogging up busy court dockets, because people with small complaints have a right to their day in court, too. If the neighbors are annoyed by this person fixing his car at home, they have a right to address that with the judge. The man fixing the car also has the right to defend what he's doing. It's the hallmark of a free country.
It is my opinion that our court system is not being overloaded with unnecessary cases. I feel for every case that is taken to court that we might deem trivial, there are probably many more that are not being taken to court because those feuding do not want to take the time or put in the effort to do so. If settling the issues in court is preventing them from being settled in a more violent way, I'm all for it.
