Extension
Chương 9. BP Format · Part C: Format Guides
BP Formal Requirement: The Member of Government/Member of Opposition must extend the debate with material not previously contributed by their side. This can include new arguments, rebuttal, analysis, examples, characterisation, or weighing. Judges credit the Closing Half for contributions beyond their Opening team's material; merely having an extension does not establish a win over Opening. Closing must normally remain consistent with Opening, subject to the rare exceptions in WUDC 2027 Manual, section 2.11. For the informal WSDC usage, see Extension (WSDC).
