As I recall part of the Salt Lake City pairs controversy was that the substitute judge had voted for Sale and Pelletier, so if the French judge's scores had been throw out and the substituite judge's included, S&P would have won by a 5 to 4 majority. The ISU ruled instead to throw out the French judge's score and declare it to be a 4-4 tie, hence the duplicate gold medals.
IIRC at Torino there were 12 seated judges, with 3 scores discarded in the random draw.
As I read the proposal of the Russian federation (#134), their proposal is to eliminat the extra "dmmy" judges and the random draw that currently reduces the panel of 12 down to 9, before trimming. The proposal seems to be to seat 10 (or perhaps 9 for lesser events like Four Continents and Europeans), have a computerized "random draw" only to determine which of the the 10 will be designated the "substitute," then use the other 9 as the scoring judges (before trimming.)
I think this is a good proposal. It does not address the question of anonymous judging one way or the other. But it eliminates the need to have three "dummy judges" sitting at the table with their fingers up their noses pretending to be judging something, when if fact they are not. Plus, it will save the ISU a couple of bucks.
