De minimis is a term used by courts when a trespass is too small or insignificant to be legally actionable.
The Live and Let Live Movement considers this concept to avoid legal action when a violation of the Legal Principle is too minor or insignificant to be actionable in court.
Faint smells, minor noises, and dim lights from a neighbor in a close residential community would all be considered de minimis. While each of these is technically a trespass and violates the Legal Principle, we do not treat them as trespasses because they are generally below the threshold of concern for reasonable people in a community; these minor trespasses are the expected consequences of living in the world.
While competent adults remain free to contract otherwise, deeming these trespasses de minimis (ignoring them) is the proper course of action. However, reasonable minds can disagree on when to deem a trespass de minimis. As such, the 3LP delegates the reasonable resolution of these issues to local communities.
