DARVO is a great acronym. The situation that you described is part of the Power & Control dynamics of abuse. By using the legal system against the victim, the perpetrator attempts to keep the victim under his control and by weaponizing the legal system is how he/they continues the pattern of exerting their power. "turning the tables" and making themselves look like the victim and by using manipulation and gaslighting is how the perpetrator makes the victim seem "crazy" and put themselves in a good light.
This is also a flaw in the justice system that makes it hard for victims to be believed, particularly when you have a police force/judicial system that is not trained in the dynamics of domestic violence.
