General Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997) ("[N]othing in either Daubert or the Federal Rules of Evidence requires a district court to admit opinion evidence that is connected to existing data only by the ipse dixit of the expert."). Gray has not demonstrated how McCarter's communications with Jarrow were unreasonable (standard of care) or how Jarrow would have suffered less injury but for McCarter's failure to communicate more or differently (causation). See Miller v. Barber, No. 455605, 2005 WL 1633996, at *6 (Conn. Sup. Ct. May 20, 2005) (granting directed verdict on legal malpractice action in part because the plaintiff failed to produce evidence as to how the attorney's alleged failure to communicate and consult "would have altered the result of [plaintiff's] appeal" in the underlying case.). Accordingly, I grant summary judgment to McCarter as to the "failure to consult" portion of Jarrow's malpractice counterclaim.
