Laws of On Line Bridge published by the WBF in 2001
(changes only, marked vs. relevant subsections of Laws of Duplicate Contract Bridge 1997)
Law 17 - Duration Of The Auction
| Section E. End of Auction Period | |
| The auction period ends when all four players pass or when after three passes in rotation have followed any call the opening lead is faced (when a pass out of rotation has been accepted, see Law 34).* | |
| New Footnote to Law 17E | Service providers are encouraged to develop software
                        permitting re-opening of the auction until the opening
                        lead has been faced. When the software elected by the
                        sponsoring organisation does not permit re-opening of
                        the auction, the auction period ends after three passes
                        in rotation have followed any call.
