Prescriptions are not pieces of paper but rather an immaterial license issued by a physician to dispense a controlled substance. The prescription in question wasn't a physical script but was called in. It was not as if the pharmacist refused to give a piece of paper back. To "transfer" this prescription would have required the pharmacist to call another pharmacy and effectively re-prescribe it. Since the drug in question is a known abortifacient, this action would have been material participation in a potential abortion. The employer was aware of this moral reservation and the prescription was filled the next Monday by another pharmacist.
The next "emergency order" from this governor could just as easily be to require all surgeons to perform abortions on anyone who asks them.
The state pharmacy board disciplined him for his actions. He may want to be more careful when choosing his employer to avoid having to be asked to fill birth control prescriptions.
