The standard PP in North Korea is to have the opponents of Kim Jong-Un shot. It doesn't matter who committed the infraction. But the US is, fortunately, not North Korea. Not yet, anyway.

Funny. Most posters are commenting on the declarer's "sm.." and giving some highly unlikely if not downright nonsensical explanations. For me, more important is the action of the dummy. I would have let the lpay continue, but given an AS and quite probably a penalty, at least a warning, to the dummy for playing a card without being instructed to do so and to the declarer for changing his play accordingly.
Hm. Would that be two PPs? What would be the legal basis for the PP to declarer?

Some years back there was a case in Holland in which the declarer, leading from the dummy, said (in Dutch) "hea...spades six". The national AC decided that a heart should be played. Based on that decision I would decide that in this case the lowest card in the suit should be played in the dummy.
FWIW, I think your national AC was wrong. IAC, it sets a precedent only for Holland.
