LAWS / CHANGES /VIDEOS
- Law 1B: The back of each card must be symmetric (Law 1C) and the ACBL encourages the use of packs where the face of each card is also symmetric.
- Law18F: The ACBL Board of Directors authorizes tournament organizers in ACBL sanctioned events to use bidding boxes. Any alternative method which is necessary to enable a person with a disability to compete is authorized subject to the approval of the Director.
- Law 40B1 and Law 40B2(a): An opening bid of 1NT and an opening bid of one in a suit, which by partnership agreement could show fewer than 8 high-card points, is designated a special partnership agreement. These two special partnership agreements are disallowed in all ACBL sanctioned events.
- Law 40B2(a): Both members of a partnership must employ the same system that appears on the convention card.
- During a session of play, a system may not be varied, except with permission of the Tournament Director. (A Director might allow a pair to change a convention but would not allow a pair to change its basic system.)
- At the outset of a round or session, a pair may review its opponents’ convention card and alter its defenses against the opponents’ special understandings and preemptive bids. This must be announced to its opponents. The opponents may not vary their system after being informed of these defensive alterations.
- A partnership, by prior agreement, may not vary its understanding during the auction or play following a question asked a response to a question or any irregularity. >
- Law 40B2(b): Whenever written defenses are required or permitted, they may be referred to by any player whenever it would be appropriate to refer to an opponent’s convention card.
- Law 40B2(c): In addition, a player is permitted to consult an opponent’s convention card at his RHO’s turn to call.
- Law 93C1: A further appeal to the Regulating Authority (ACBL) may be allowed only as follows:
- On a point of law to and at the discretion of the ACBL Laws Commission.
- On an allegation of bias of a committee member or members to and at the discretion of the ACBL Appeals and Charges Committee. The appellant is required to present evidence that the bias was not known at the time of the hearing.
- The appeal must be filed within thirty (30) days of the decision of the Bridge Appeals Committee that heard the issue.
- Law 93C3(a): Except as noted in 7 above, the responsibility of dealing finally with any appeal of a Director’s decision is that of the tournament’s specified tournament body.

Convention Charts
The four new convention charts are listed in order from least to most permissive: the Basic Chart, Basic+ Chart, Open Chart, and Open+ Chart. The Basic and Basic+ Charts are intended for limited master point events. These Charts are written in manner similar to the old charts — by listing permitted methods.
The Open and Open+ Charts are intended for events with no masterpoint limits (or high limits). In contrast to the Basic and Basic+ Charts, methods are generally allowed unless they are expressly prohibited within the Chart.
A comprehensive Definitions section is included in addition to the Charts. Any word that is capitalized on a Chart is included in the Definitions section.
An Examples section follows the Charts for cases where a rule might be ambiguous. Both the Definitions and the Examples should be included with the Charts. Any Definition or Chart Rule marked with three asterisks (***) has 1 or more examples in the Example section.
Defense Database
Defense Database
Two classes of methods are particularly difficult to defend against, and these methods are allowed only in events governed by the Open+ Chart, and then only in segments of six boards or longer. These methods, based on #3 of the Opening Bids section of the Open Chart and on #3 or #7 of the Opening Bids section of the Open+ Chart, require both a pre-alert and a written defense, including a separate copy of that defense for each opponent.
If you choose to play one of these methods, you are required to:
- Pre-Alert the method prior to the start of the auction on the first board.
- Have a complete written description of the method available for your opponents.
- Have a copy of an approved defense from this database available for your opponents should they wish to use it. If there is no approved defense for the method you wish to play, you may not use that method until such time as you have submitted a defense to ACBL and that defense has been approved.
The intent of these requirements is to permit responsible pairs a reasonable amount of freedom to determine the methods they wish to play while ensuring that no advantage is gained from a method that is unknown and/or whose submitted defense is inadequate.
A sub-committee of the Conventions and Competition Committee is responsible for approving defenses to methods which require them for addition to the ACBL Defense Database.
All proposals must include:
- a complete description of the method, including responses and rebids and what happens in competition,
- a detailed defense including initial actions, responses to the initial actions (including in competition), actions after opening-P- bid/P (and responses there to), delayed actions such as opening-P-bid- P-P/bid

Binding Arbitration
American Contract Bridge League
BINDING ARBITRATION AGREEMENT
Last Updated January 2017
The American Contract Bridge League (“ACBL”) and each of its individual members agree as follows:- Any dispute in any way related to membership in the ACBL, or any action for damages or injunctive relief against ACBL or any action to reverse, modify, amend, or delay enforcement of a disciplinary action or other decision of the ACBL, regardless of the facts or legal theories involved, shall be resolved by the ACBL member or former member with ACBL on an individual and confidential basis through the steps set forth in this arbitration agreement up to and including final binding arbitration before the American Arbitration Association (“AAA”) by a single arbitrator.
- This arbitration agreement covers any and all disputes that an individual member may have with (a) the ACBL, (b) the ACBL’s current or former officers, directors, employees or agents in their capacity as such or otherwise, or (c) other ACBL members to the extent that dispute arises directly from ACBL membership or participation in any ACBL program or event. Likewise, the arbitration agreement covers any and all disputes that the ACBL may have with an individual member.
- Each individual member agrees that a dispute covered by this arbitration agreement does not include any dispute or disagreement about the adoption, change, revision, interpretation or discontinuance of any ACBL policy, practice, rule or procedure absent some legally recognized right enjoyed by the individual member related to the matter in dispute. In other words, ACBL retains the right to adopt or change its policies and rules using the normal process for such changes, not subject to arbitration.
- Each individual ACBL member hereby specifically waives the right to present disputes covered by this arbitration agreement in any court or before a jury and hereby recognizes and accepts arbitration as the exclusive forum for resolution of all disputes described in this arbitration agreement. Individual ACBL members further agree that if they file or anyone else files a claim on their behalf in any state or federal court, the ACBL shall have the right to seek to stay or dismiss such a lawsuit and to compel arbitration. The only exception is that either party may seek an injunction in court if interim and/or immediate relief is necessary to preserve the status quo and such injunctive relief is permissible under applicable state or federal law.
- Each individual ACBL member hereby waives any right for any dispute to be heard, decided or arbitrated as a class, collective or representative type action and agrees that he/she will not, in arbitration or otherwise, pursue a representative action and agrees that the assertion of any class, collective or representative action will be subject to immediate dismissal by the court or the arbitrator.
- Arbitration is a formal dispute resolution process where an arbitrator, like a judge, takes evidence at a hearing and then a final binding decision that may be enforced against either party.
- Individual ACBL members may commence arbitration under this arbitration agreement by making written demand for arbitration directed to the ACBL at Legal Dept., American Contract Bridge League, 6575 Windchase Blvd., Horn Lake, MS 39637-1523 or by making a written request for arbitration of a dispute with ACBL directed to the AAA at American Arbitration Association, Case Filing Services, 1101 Laurel Oak Road, Suite 100, Voorhees, NJ 08043, tel. 877-495-4185 or through its website at www.adr.org.
- A demand for arbitration must be made in writing addressed to the ACBL or to the AAA prior to the end of the statute of limitations period applicable to the claim being asserted by the individual member or the statute of limitations period applicable to the claim being asserted by the ACBL against the individual member. The applicable statute of limitations will be deemed tolled once the written demand is received by the ACBL or the AAA.
- Each individual member shall have the right to be represented by an attorney of choice prior to the initiation of and throughout the arbitration process provided however, that the individual member will be responsible to pay the costs of his or her representation.
- This arbitration agreement shall be interpreted and its validity and enforceability shall be determined strictly in accordance with the Federal Arbitration Act (9 U.S.C. §1 et. seq.).
- Absent agreement by the parties to a particular arbitrator or process, the arbitrator shall be selected jointly by the parties using the process in effect at that time by the AAA. The arbitration shall be conducted in accordance with the Commercial Rules of the AAA in effect at the time the arbitration proceeding is initiated. The AAA Rules are available at www.adr.org.
- Unless otherwise agreed by the ACBL and the individual member or otherwise ordered by the arbitrator, the arbitration shall be conducted by the AAA at a location to be mutually selected by the parties in Memphis, TN or DeSoto County, MS. If the parties cannot select a mutually agreeable site for the arbitration hearing, the AAA shall resolve that issue by selecting a location for the arbitration hearing.
- The arbitrator shall:
- have the exclusive authority to resolve any dispute relating to the interpretation, construction, applicability, unconscionability, arbitrability, enforceability, or formation of this arbitration agreement, including but not limited to any claim that all or any part of the arbitration agreement is void or voidable; however, nothing herein shall be interpreted to permit an arbitrator to hear, consider or arbitrate any claim on a class, collective or representative basis;
- have the authority to adjust the venue for the hearing in the interest of fairness and to meet the reasonable needs of the parties and witnesses;
- have the power to award to the individual member or the ACBL any remedy to which that party could be entitled under the law applicable to the claims;
- have the authority to manage and rule on discovery between the parties applying the AAA rules and principles that would apply to a dispute between the parties in court;
- have the authority to require any prevailing party to pay all costs associated with the arbitration if the shift of such costs are in the interest of fairness;
- have the authority to award attorneys’ fees to any prevailing party based on applicable legal principles; and
- render an award by written opinion no later than 30 days from the date of the conclusion of the arbitration hearing or the last due date for receipt of any requested post-hearing briefs, unless the parties agree otherwise. The opinion shall be in writing and set forth the factual and legal basis for the decision.
- Each individual member agrees that the mutual obligation of the ACBL to arbitrate disputes combined with the privileges of ACBL membership represent good and sufficient consideration for this arbitration agreement and agrees not to challenge the sufficiency of such consideration at any time.
- Absent an award of fees or costs by the arbitrator, the parties shall split the costs of the arbitration and each party shall pay their own attorneys’ fees and litigation costs.

ACBL CODIFICATION
Bidding Box Regs
- Bidding boxes will be used in all events held at NABC's except I/N events (0-500). Their use will be optional in I/N events.
- Units and Districts are encouraged to use bidding boxes in their games.
- Handicapped players requiring bidding boxes will have preference when availability is limited.
- Non-handicapped players may use bidding boxes, if available, in games in which such use is not mandated as long as no player at the table objects.
Any player has the right to use bidding boxes (assuming they are available) for any ACBL event in which they play if they are needed because of a hearing impairment. As a policy, we do not question players as to the details of a handicap when they state that one exists.
When bidding boxes are in use for this reason, no player has the right to refuse to play with them. Players who have a handicap which preclude their use will have a distinctive card. The card will be displayed on the table and read, "due to a physical or visual handicap, we are not using bidding boxes."
Choosing a call using bidding boxesA player is obligated to choose a call before touching any card in the box. Deliberation while touching the bidding box cards may subject the offending side to the adjustment provisions of Law 16.
A call is considered made when a bidding card is removed from the bidding box and held touching or nearly touching the table or maintained in such a position to indicate that the call has been made. We should use unauthorized information where reasonably appropriate (where we can rule that a bid has not been made). For close cases simply judge that the card had not left the confines of the box; therefore, a call has not been made.
A call may be changed without penalty, under the provisions of Law 25A, only if a player has inadvertently taken out the wrong bidding card and the player corrects or attempts to correct his mistake without pause for thought and the player’s partner has not made a call.
The onus is on the player to convince the director that a mechanical irregularity has occured. Calls from different pockets should rarely, if at all, be judged as inadvertent. One understandable exception is placing the double card out followed shortly with a bid card that skips the bidding. This appears clear that the double card was placed inadvertently on the table.
The Stop CardUse of the Stop card has been discontinued. No verbal or visual skip-bid warning should be used. Following a jump in the bidding, left-hand opponent is obligated to wait approximately 10 seconds (while giving the appearance of studying his hand and not in excess time to determine a choice of bids) before making a call.
Note: If a player accidently uses the Stop card, there is no penalty. It is each player’s responsibility to maintain appropriate tempo at all times.
