I'm mixing up my plot lines.
"Injustice For All" is what I'm thinking of: Exposed as a criminal, sentenced to prison, and terminally ill due to long term kryptonite exposure, Lex Luthor escapes and assembles a supervillain team consisting of Cheetah, The Shade, Solomon Grundy, Star Sapphire, Copperhead, and Ultra-Humanite to take on the Justice League, calling themselves the Injustice Gang. The Joker also becomes part of the team, but on his own choice. However, even with their combined power, this gang proves no match for Batman's wiles.
"Crisis on Two Earths" was when the JLU team was sent to a parallel earth where that realm's JLU was the sole arbiter of lawful/unlawful and ruled with an iron fist.
Neither of which were Avengers plot lines though.
