Vendors such as IMS Health gather information from pharmacies about the mediations physicians prescribe and sell that data to drug firms so they can refine their marketing strategies, the Wall Street Journal reports.

In the lawsuit Sorrell v. IMS Health, Justice Anthony Kennedy, writing for the majority, said the law violates the speech rights of the data mining and drug companies, according to the Associated Press. Dissenting Justices Stephen Breyer, Ruth Badar Ginsburg and Elena Kagan argued the law was a constitutional regulation of business.
