 The move was criticized by family planning advocates, saying that women in small towns where Walmart pharmacies had little competition would have greater difficulties in obtaining the drug.The decision was challenged in 2006, as three Massachusetts women filed suit against the company after they were unable to purchase emergency contraception at their local Walmart stores, resulting in a ruling that required Walmart to stock the drug in all of its pharmacies in Massachusetts.Expecting that other states would soon do the same, Walmart reversed its policy and announced that it would begin to stock the drug nationwide, while at the same time maintaining its conscientious objection policy, allowing any Walmart pharmacy employee who does not feel comfortable dispensing a prescription to refer customers to another pharmacy.
