U.S. Supreme Court Justice Sonia Sotomayor threw lawyers a curve ball this past week by siding with conservatives on a corporate free-speech case. Marking the first time she’s broken with liberals in a case presenting a clear philosophical split, scholars will wonder what other surprises the “wise Latina” from the Bronx has in store.

The case is Sorrell v. IMS Health. Pharmacies sell information on which drugs individual doctors prescribe. Pharmaceutical companies buy that information so their salespeople will know exactly what each doctor’s preferences are, tailoring individual sales pitches to offer drugs similar to the ones each doctor favors.
