British High Court Justice Victoria Sharp warned in June that providing false material as if it were genuine could be considered contempt of court or, in the "most egregious cases", perverting the course of justice, which carries a maximum sentence of life in prison.
IMHO there should be a written warning followed by being disbarred for this kind of unethical behaviour. If you're too lazy to do the legwork yourself and verify your work, you don't deserve your role.
