A legal expert says a ruling temporarily prohibiting a compounding pharmacy from selling execution drugs to Missouri could have implications across the country.

U.S. District Judge Terence Kern in Tulsa, Okla., issued a temporary restraining order Wednesday in a suit filed on behalf of condemned Missouri inmate Michael Taylor. The ruling prohibits Tulsa-based Apothecary Shoppe from selling pentobarbital to the Missouri Department of Corrections.

Taylor faces execution Feb. 26. It isn't clear if Missouri has pentobarbital on hand but Gov. Jay Nixon says the state is prepared to carry out the execution.

Fordham Law School professor Deborah Denno says attorneys for other death row inmates could file similar suits. She says the case could prompt compounding pharmacies to reconsider making and selling execution drugs.
