Tattersalls Committee

The industry body that publishes the rules of settling for UK horse racing bets, including the Rule 4 deduction scale. Founded in 1865 and named after Richard Tattersall, the auctioneer who established the firm. Off-course bookmakers in the UK apply Tattersalls rules as standard; minor settlement variations between operators usually trace back to a bookmaker's own house rules layered on top of the Tattersalls baseline.
