The WUDC Debating & Judging Manual (“WUDC Manual”) is the authoritative document on the rules of British Parliamentary debating. The WUDC Manual specifies how debating and judging takes place at WUDC.

In 2021, the WUDC Manual underwent a major overhaul under the Korea WUDC 2021 Adjudication Core (in collaboration with the Belgrade WUDC 2022 and Madrid WUDC 2023 Adjudication Cores). It has since been adopted by majors across the world.

Later editions of WUDC have amended the WUDC Manual to varying degrees. The version on this page is the most recent edition of the Manual, as updated by the Sofia WUDC 2026 Adjudication Core.
