Let
Partner of X=PoX
Partner of Y=PoY
Player X=X
Player Y=Y

Lets say player X (South) have x xxx ♦AKQJTxx xx , player Y was LHO of player X
and auction went

North: PoX opened 1♥
East: PoY Passed
South:X responded 1NT
West: Y overcalled 2♠

Before PoX take any action, X (South) apologized for his error for his 1NT and substituted his bid with 2♦. There was no director.
How should this issue be resolved if
A. West do not accept the substitution
B. West accepted the substitution
C. West accepted the substitution and he also substitute his 2♠ to 4♠

What north do would be legally wrong / morally wrong?

[gordontd]

In the absence of a director, someone should read the law book and establish whether the original call was intended (Law 25B applies) or unintended (Law 25A).

Legally wrong is playing without a director. Morally wrong is the wrong question; that is something to be decided by yourself.

If the 1NT bid by South is considered not unintended and West does not accept the substitution then

Law 25B said:

...
2. Except as in B1, a substitution not permitted by A is cancelled. The original call stands and the auction continues (Law 26 may apply).
3. Law 16C applies to any call withdrawn or cancelled.

Otherwise Law 25A or Law 25B1 (as the case may be) applies, the substitution is accepted and West may substitute any legal call for his 2♠ bid.

Law 81 defines the Director, but I cannot find any law that makes it illegal to play bridge without a director?

[steve2005]

If South changes their call shouldn't west be able to change their call theoretically to anything without penalty as auction has changed not from their fault

Without a director you can’t start if you stick to the laws. Law 3: “Four players play at each table, and tables are numbered in a sequence established by the Director“. Law5: “The Director assigns an initial position to each contestant (individual, pair or team) at the start of a session”. Etc etc.
Of course you can play bridge without a director, but you can’t follow all the laws. That’s certainly In case of an irregularity. You should summon the director, but you can wait forever, the director wouldn’t show.
When you’re playing without a director, and can’t call one, you can lookup the appropriate laws if necessary, but the outcome of this consultation should be subject to a majority agreeing on the decision. It’s certainly not good to play a serious match without (access to) a director.

Most matches in England are played privately with no director, and a referee can be called if necessary. In my experience this is only done for judgement rulings, and often the laws are looked up by the players on a hand-held device!

Nothing prevents an acting Director to have all the preparations completed in advance, he need not be present during the play.

In Norway it is customary to have licensed directors available on call, but for the most important events we require (by CoC) that a properly licensed Director is available on the premises.

Quote

Law 80B: 2. The Tournament Organizer’s powers and duties include:
(a) appointment of the Director. If there is no appointed Director the players should designate a person to perform his functions.

This should probably be done before a problem arises.

it would be easier to understand if you posted a hand diagram and just used compass directions in the text, rather than all this X/Y stuff.

Indeed so.

I much prefer RBN. An example:
B 8
H W:A8765.QT.K9.AT87:J42.AJ7632.J.632:QT3.85.Q86.KQJ54:
A WZ:1S2H2S4D:4SPP5H:XA

R 9-300:0
