Abbreviation for maxim de minimis non curat lex, "the law cares not for small things." A legal doctrine by which a court refuses to consider trifling matters.
This doctrine is already in place in society such as many police matters. My outgoing mail was stolen the other day. The local police dept took the report on the phone but I was told this was simply too small for the Postal Inspection Service and that the report would not be turned over to them.
In many cases the police do not investigate anything, they simply take reports and hope that something will pop up in arrests of bad guys later, as in our case, the stolen checks.
In some larger metro areas, the police won't even show up for traffic accidents unless someone is injured.
Of course, in copyright, this simply furthers my observation that soon only larger corporations will have copyright protection because only they will be able to afford litigation.
