Oh, the modern definition of LAs is not fierce at all. If for example the Director were to consider that cherdanno, peachy, Codo and gwnn are a sufficiently representative sample of players in the same class as South, then it is clear to rule that pass is not a LA. If on the other hand the Director were to consider that bluejak, gordontd, cardsharp and greenender are a sufficiently representative sample of players in the same class as South, then it is clear to rule that pass is a LA.
No, all this proves is that a sample size of four is not big enough to determine with sufficient confidence that a particular action is not a logical alternative.
[However, a sample size of four
may turn out to be sufficent to conclude with sufficient confidence that an action
is a logical alternative.]

What concerns me a little is how in the general case a Director is supposed to know to what class of players South belongs, and what other players constitute a representative sample of that class. That is, how is one supposed in the general case to "conduct a poll of peers of South as a bidding problem at South's second turn to call", as jallerton suggests?
Well, the TD or one of his consultees might know the player in question, or he may be able to make a fair estimate of the player's standard from other factors, such as the player's position in the current event. There may be evidence of the player's system and style on the convention card.

Formerly, of course, I would have had no difficulty at all in disallowing South's double per Law 73. But I'm not supposed to do that any more. Am I, Jeffrey?
When you say "formerly", do you mean pre 1997, when the wording of this Law changed?
Under the 2007 Laws, there could be an adjustment under Law 73C if the TD determines that this particular South's bidding was influenced by the UI. That is why the TD should ask the player immediately why he doubled.
Let's consider South's mindset during the auction. Partner opens 1NT. At this point, South comes to the quick conclusion that he will transfer to spades and pass the transfer completion of 2
♠. He will not give any consideration whatsoever at this point as to what he might do if LHO makes a jump overcall.
LHO now puts the 'stop' card on the table followed by 4
♥. Now we come to the critical few seconds.
Scenario 1. If as South I decide, before North has finished obeying the 'stop warning'* that I am going to double 4
♥, then when it later transpires that (rather surprisingly) partner was considering acting I shall know that I can double without breaching Law 73C. However, I now need to consider whether or not Pass is a logical alternative, as I also need to comply with Law 16A.
Scenario 2. If I have not decided for sure what to do by the time it becomes apparent to me that partner was considering acting*, then I determine that double would be a breach of Law 73C and so I shall pass out 4
♥. I would also note that I have seriously considered both pass and double, so both are logical alternatives and that I need to pass to comply with Law 16A also.
* the time period will vary from partner to partner. I am lucky enough to have some partners who adhere to the 'stop' regulations properly, which will give me ten seconds or so; but with other partners I know I have less time, particularly if LHO picks up the 'stop' card prematurely (or does not bother to use it at all).
