Horayot 5 - Shabbat September 6, 13 Elul

There are multiple opinions regarding who is responsible for bringing the communal sin offering. Is it the Sanhedrin that offers it? Do individual tribes that sinned each bring their own offering? Could it be both? If only some tribes transgressed, are the others still obligated to bring a bull offering? And is a communal offering required only when the Sanhedrin haGadol issues a mistaken ruling? What are the Torah sources and rabbinic interpretations that support these different views?
