As comrade John says, it is a newly created Anglicism, contraction of law, law and warfare, war. The term already began to be used in the last decades of the last century. Legal warfare, illegal use of justice for political purposes to destroy the opponent, to gain power or to stay in it. Of course, for this to happen it must be done in collusion with the judges themselves. This is what happened in Brazil with the imprisonment of Lula da Silva. This is what the right usually does almost everywhere when people wake up from their political anesthesia. Come! To wake up.
LAWFARE English word product of the contraction of the word LAW meaning LAW and WARFARE meaning CAMPAIGN BÉLICA . Lawfate was created in early 2000 by the strategic study centers of the American FFAA to specify the judicial use of human rights to strengthen the political position of the weaker side, publicly discrediting the other party, regardless of whether the demand was fair or not.
