Impossible to say without knowing all four hands.
But failure to alert is by definition (and law) misinformation, and as it is too late for East to change his last call the Director's ruling to play on is correct.
Too late for E, but W should have been offered a chance
17D The auction period ends when, subsequent to the
end of the auction as in Law 22A, either defender
faces an opening lead.
21B 1. (a)
Until the end of the auction period (see Law 17D) and provided that his partner has not
subsequently called, a player may change a call
without other rectification for his side when the
Director judges that the decision to make the call could well have been influenced by misinformation given to the player by an opponent.
Failure to alert promptly where an alert is required by the Regulating Authority is deemed misinformation.
Before the opening lead would seem to be early enough unless ACBL doesn't use the new laws unadjusted.
Raises a question or two.
W exercises the right to change his bid, is his pass cancelled ? has he now called ? If it is cancelled, can E now say his partner hasn't called and have his bid back ?
Also what's the UI situation of W changing his call knowing E summoned the director and may have wanted to bid.
