What penalty?

[IK13]

This was told to me last night. Rather weird mess for a D3 game…

After a rally is complete, the table informs R2 that the libero on the floor wears the same number as one of the other players. Apparently she changed uniforms at some point after the lineups were checked and entered that way unnoticed (or the libero tracker was double checking etc. and by the time it was discovered the rally was already under way).

What’s the penalty?

According to the story, the libero was DQed, after the opposing coach proved with the rulebook that this is the correct penalty in this case. Sounds off and perhaps I’m looking in the wrong places, but I can’t find anything in the rulebook.

Both R1 and R2 have several decades of officiating, including D1 championship finals.
