Can a draw result be overturned after the game if an arbiter's error is discovered later?

These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.

Direct answer

In an organised event, yes, but only through a formal process, and rarely. If a genuine error is discovered, a repetition wrongly identified, a claim wrongly upheld or denied, most federations and tournament rules allow a correction through an appeal to the chief arbiter or a technical committee, usually within a limited window after the result was recorded. It is not something either player can simply request informally after the fact.

Why this window exists but is kept short

Games need a final result relatively quickly for pairings, standings and prizes to function at all, so an open-ended right to contest results long afterward would be impractical. A short, clearly defined appeal window balances fairness against the practical need for tournaments to actually conclude.

What this looks like in casual or online play

Outside an organised event with a real appeal process, there is usually no formal mechanism at all; an online platform's automated result is generally treated as final, and a casual over-the-board game's result rests on whatever the players agreed at the time.

Related questions

Who typically has the authority to overturn a result?

The event's chief arbiter, or a designated technical or appeals committee, depending on how the event is organised.

Is this common?

No, it is rare, and reserved for clear, demonstrable errors rather than second thoughts about a judgement call.
