Ruling Luring flame with no bench

[AmishEskimoNinja]

Switch the defending pokemon with one of your opponent's benched pokemon. The new defending pokemon is now burned.

If your opponent has no benched pokemon, can you still burn the one that was active with this attack?

I'm afraid not. It says the new Defending Pokemon is burned, and if your opponent doesn't have any benched Pokemon, they can't have a "new" Defending Pokemon.
