"What is Marshall law?"
It's a set of repressive, harsh actions that a government can legally take, temporarily, to protect its citizens, and put down insurrection/rebellion. It requires the government make a "declaration of Marshal Law" for handling dire emergencies, and it involves a suspension of common civil liberties. At least, I think that is generally the American version. I suspect every democratic government has a version of this, including France. Now, whether Chirac is willing to do that ...
Martial Law, perhaps?
As in law manu-militarias.
Not altogether different from "Marital Law" in too many respects.
But what is Marshall law? Or Marshal law? A law made by George Marshall?
