Yes, the burden of proof is on the defense.
And just because you have a pink piece of paper and you think you have a valid license doesn't mean you have met the burden of proof.
There is a case, but I'm too lazy to look for it right now.
I don't know of any way, other than the pink paper, that you can "prove" you have a valid license. If the state says your license isn't valid, then it isn't valid. And they don't have to show any proof that your license isn't valid.
At least that was the way I read it. Again... I'm too lazy to go look it up.
