Intelligent design decision

Unless of course you've been off-planet for the last day or so, you will have heard the decision by a Federal judge that the Dover Area School Board, PA, may not allow a statement concerning Intelligent Decision (ID) to be read at the beginning of the ninth grade biology class.
As a trained scientist, I have to say I agree with the decision, but not the reasoning. To couch the issue as a "separation of church and state" I think unduly complicates the decision. The statement should have been deemed inappropriate because ID isn't science and so should not be part of a science class.
According to Wiki, science "...explains observable events in nature by natural causes without assuming the existence or non-existence of the supernatural". ID by definition explains biological diversity by applying the supernatural. In addition, a scientific theory has to be in principle falsifiable. Intelligent decision is not falsifiable in it's current state.
If the ID proponents want to make it a true theory, with testable predictions and the possibility for falsifiability, they are free to do so, and to my mind would be doing humanity a service. Only then would it be appropriate to discuss it in science classes.
Time will tell.
