In an opinion released earlier today, the D.C. Circuit Court struck down the SEC's Dodd-Frank Conflict Mineral Rule under the compelled speech doctrine for failing the least restrictive alternative prong.  

We therefore hold that 15 U.S.C. § 78m(p)(1)(A)(ii) & (E), and the Commission’s final rule, 56 Fed. Reg. at 56,362-65, violate the First Amendment to the extent the statute and rule require regulated entities to report to the Commission and to state on their website that any of their products have “not been found to be ‘DRC conflict free.’”

Not striking down the need for information about conflict minerals, but rather the required approach, the Court suggested that: 

[A] centralized list compiled by the Commission in one place may even be more convenient or trustworthy to investors and consumers. The Commission has failed to explain why (much less provide evidence that) the Association’s intuitive alternatives to regulating speech would be any less effective.

In August, 2012, the SEC released final Dodd-Frank rules for conflict minerals "requir[ing] companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo (DRC) or an adjoining country."
