Rule 11(b) (3) of the Federal Rules of Civil Procedure (F.R.Civ.P.) imposes an ethical requirement that an attorney certify, after an inquiry reasonable under the circumstance, that factual allegations in federal pleadings have evidentiary support. The recent decisions by the Supreme Court in Twombly and Iqbal imposed similar obligations on attorneys, by requiring a showing of “plausibility.” Join federal litigation and bankruptcy practitioner Rob Shilliday as he explores the potential effects of Twombly and Iqbal on the ethical requirements and enforcement of F.R.Civ.P., and analyzes how the prior 1983 Amendments to the Rule may be used to predict future application of Twombly and Iqbal.
