A state judge has struck down a portion of Arkansas' law that keeps confidential the source of its execution drugs.

Pulaski County District Court Wendell Griffen ruled Thursday that the state must disclose details of its execution drugs by noon Friday.

He sided with death row inmates who challenged a law passed by legislators this year that shielded the identity of drug suppliers.

Griffen rejected arguments from the state that said disclosing the information would make it more difficult to obtain the drugs. The state had also argued that drug companies could face undue criticism because of the disclosure.

He ruled that a company that does business with the state has no constitutional right "to enjoy governmental protection from criticism."
