My other question comes from a tourney I recently entered. My active pokemon was a Nidoking and his active was a Ditto. So, it was a Nidoking against a Nidoking. His Nidoking had 60 hit points on it and mine had 20. On my next turn I used a switch and changed my active pokemon to a lowly Nidoran. I then stated that I should take a prize because his Nidoking was no longer a Nidoking and was now a Nidoran, and because Nidoran has only 40 HP and it had the 60 HP sustained from when it was a Nidoking, it would instantly faint and result in me taking a prize.This took a lot of deliberation and I eventually got to take a prize, but the referee was still not sure so I am asking for your mighty judgement.

Ditto's transform power is automatic.  It MUST use it immediately as long as it is not paralyzed, confused, or asleep.  Sometimes, you don't want him to use it, but there is no choice.  In this case, the Ditto had 7 damage counters on it, and a 60HP Pokemon was brought forward.  Since it was a 60HP Pokemon with 7 damage counters, it was sufficient to knock it out, and the Ditto is gone.  The ruling made at the tournament is correct.
