From Davis Wright Tremaine LLP at Lexology:
"On October 20, 2014, the District of Columbia Circuit held oral argument on the biggest issue under the Court of Appeals’ three-year-old D.C. anti-SLAPP statute: does the special motion to dismiss under the anti-SLAPP statute apply in federal diversity actions? Abbas v. Foreign Policy Group, LLC, 975 F. Supp. 2d 1 (D.D.C. Sept. 27, 2013), oral argument held, No. 13-7171 (D.C. Cir. Oct. 20, 2014). The panel appeared receptive to holding that – at least in circumstances calling for a motion to dismiss for failure to state a claim under Fed. R. Civ. P. 12(b)(6) – the anti-SLAPP statute applies in federal court.
Without a ruling from the D.C. Circuit, federal district courts in D.C. have largely applied the anti-SLAPP statute in federal court."
