Well, they're back, but in a slightly different form. LEGO initially rejected Maia Weinstock's original proposal, featuring actual female justices from the U.S. Supreme Court, under its policy against creating political minifigures based on real individuals. Weinstock and LEGO have now reached a compromise and a proposed set including three generic female justices has now been submitted to LEGO Ideas (LEGO's crowdsourced incubator for potential sets).
The project requires 10,000 votes before it's qualified for LEGO Review. Help show your support by voting for the project here.
