Cross-X Redo

In competitive debate, cross-examination (often shortened to "cross-x" or "CX") is the timed period after a constructive speech during which an opposing debater asks the speaker questions. A Cross-X Redo is a colloquial term for re-running some or all of that questioning period when the original exchange was compromised — typically by an audio dropout on an online platform, a timer error, a tag-team violation, or a moderator interruption.

Redos are not codified in most rulebooks. The NSDA, NDCA, and CEDA do not list "redo" as a formal remedy; instead, judges rely on general discretion to preserve fairness. In practice, the request is handled in one of three ways:

• Judge-granted restart: The judge stops the round, resets the timer, and allows the questioner to begin again.
• Partial redo: Only the disrupted segment is repeated, with the remaining time carried over.
• Denial with note: The judge declines but instructs themselves to disregard the flawed exchange on the flow.

The practice became markedly more common during the 2020–2022 shift to online tournaments on platforms like NSDA Campus and Tabroom's integrated rooms, where Zoom freezes and microphone failures interrupted CX regularly. Tournament invitations from that period (e.g., the Harvard, Berkeley, and Glenbrooks online iterations) frequently included guidance encouraging judges to grant reasonable redos for connectivity issues.

Redos remain controversial. Critics argue they let a questioner who fumbled strategically "reset" after hearing an unhelpful answer; defenders note that strict denial penalizes debaters for problems outside their control. Best practice, as reflected in coaching guides from programs such as the Dartmouth Debate Institute and the University of Michigan's Summer Debate Workshops, is to grant redos only for clear technical or procedural failures, not for tactical regret, and to do so before the next speech begins.
