A conference becomes relevant only after bicameral disagreement exists. Conferees bargain over the competing provisions and produce a report containing one reconciled version. Their negotiating leverage comes from committee expertise, chamber instructions, party support, and the risk that the bill will fail.

The report cannot become law by the conferees' signatures. House and Senate must each approve identical final text, and rejection may return the measure to negotiation. Conference is therefore a solution to bicameral differences, not an exception to bicameralism.

Do not assume every bill uses a conference. One chamber can simply accept the other's amendment, and leaders can exchange further amendments. The defining result is identical language, regardless of which permissible route achieves it.
