Mechanical error England UK

Eventually North woke up and said 5NT was a mechanical error and wanted to change it. No doubt it was, but how do you rule?

Was there pause for thought? There was a pause between looking at the bidding sequence and the announcement that 5NT was a mechanical, a pause that allowed time for thought. I think this must be ruled a pause for thought.
So Law 25A does not apply, and 5NT can not be changed. (South has UI from North's reaction and announcement, which may, for example, prevent South from correcting to 6♠.)

(And if you want a Law then what about 16B1(a) ? )

My belief is different from Sven's, I think Law 25A does apply. There was something (a WBF LC minute?) that said the old Law 25B did not apply if partner had done anything; but that (minute) was not in reference to Law 25A.
Does this boil down to: does Law 25A apply when partner's actions cause the player to notice what he has called?
I believe that if the intended call is not alertable and the actual call is alertable and the events occur in normal tempo: North: bid, South: alert, North: "that's not what I intended"; then Law 25A does apply.
I don't think Law 16B1(a) applies: choosing to correct the original call to the intended call is the only logical alternative.

The LA to change his call rather than to leave it unchanged.
I can't find any L73B1A in my law book.
But there is a distinct possibility that what I remember is what Robin points out: A WBFLC Minute that relates to (the old) L25B and not L25A. I have now researched the minutes and in fact found several that had this effect on Law 25B but none on Law 25A.
It is clear to me that an unexpected alert (in tempo) can wake up a player to legally discover that he has made an inadvertent call so that he can correct it under L25A.
What I am reluctant to accept is if a player may deliberately violate L73D1 and vary his tempo for the apparent (sole) purpose of waking up his partner.

Law 25A mentions "pause for thought" (pft). Pft starts when player A discovers his unintended call. Nowhere is said - neither regulated - how this player A becomes aware of his unintended call. In fact it may be even partner B saying something like "what on earth are you doing there, partner?" that may awake the erroneous player A. The TD might penalize player B for his gratitous remark but the main law to be applied stays Law 25A.

North is allowed to change his unintended 5NT call to 5♠, since his partner has not bid yet and there was no pause for thought from the moment that North discovered his mechanical error.
But that is part 1 only. South is getting a procedural penalty for a breach of Law 74C2 and/or 74C4.

This would be an irregularity even if South hadn't also indulged in illegal communication.
The law on unintended call is that the unintended call was, in effect, not a call at all if identified in time (along with the other conditions). Since it was an irregularity that South extended the time available for identification, I wonder if we can rule it was out of time? Probably that is taking too much of a liberty without an interpretation from on high. So I rule like the others: allow the change and throw the book at South.

There is nothing wrong with double standard PP or even triple standard. But I cannot see the justification for a DP.

The way the Law is worded makes it clear that a player intends a call and subject to certain restrictions Law 25A allows him to have that call as part of the auction even if he made a different apparent call. It seems a reach to me that both the intended call and the unintended call can be considered LAs.

True: Law 73B1.
So are we agreed that Law 25A applies, but partner gets fined?

As I understand your description of the situation, it's obvious to everybody except North that 5NT was a mechanical error. Is that correct?
If so, of your 99.9% who double 5NT, how many of them do so knowing that the rules allow you to take back a mechanical error?

I believe bridge is a game of mistakes, and I see no problem with gaining from opponents' mistakes, and I think stopping partner making a mistake should only be done in specified situations where it is allowed.

First, East can't tell it is a mechanical error. It might be a different kind of mistake which isn't correctable. Like when the Italian player bid 6S instead of 6H in the recent Bermuda Bowl, not because of a mechanical error, but because he forgot H was the agreed suit.
Second, mechanical errors are only correctable if certain other conditions are fulfilled. As far as East can tell, North might know he made a mechanical error but didn't think to correct it in time, so is going to have to live with it.
I have never heard of a player drawing his RHO's attention to what call he might have put on the table in front of him, except when the call itself is irregular, eg insufficient.
The normal situation is that you make whatever call is appropriate, and if that wakes North up to a mechanical error in time, then it gets withdrawn if done in the right way.

L73A2 says calls should be made without undue hesitation. The hesitation here was definitely undue - the only reason for it was that south knew north did not intend to make this call.
L72B1 says what south did is not allowed even if he is willing to suffer the penalty.
Combined with L23, I think the change of the call should NOT be allowed, AND perhaps south deserves a DP seeing as this was not a hesitation with a "bridge reason". (Although maybe skip the DP since he is probably headed for a bad result anyway)
P.S.
I would even say this is a breach of L73B1. The fact that south did not actually say "Partner, is that the call you intended?" does not mean info was not passed by the hesitation. When I call your cell and you don't pick up, you still get the info that "I was looking for you".
