Amazing. Stupid of the women to appeal to the Supreme Court, they will just get a SC precedent to same effect.
Public sentiment in Israel is 100% in favor of the event, the Supreme Court won't risk ruling against it and irking the entire country mid elections that are already focused on limiting their power.
ETA: Ironically, the only people in Israel who are really opposed to this event are the frum that are against concerts even when they are separate.
