CHARLES R. SIMPSON, III, Senior District Judge.
This matter is before the Court on the motion of Defendants Louisville Jefferson County Metro Government, City of Louisville, Gary Kearney, Lawrence Zehnder, and Gene Sherrard to strike and exclude from evidence Exhibit 68 to Kerry Porter's response to the Defendants' motion for summary judgment, ECF No. 247. Porter did not respond. Exhibit 68 is the deposition of former Louisville Division of Police Chief Doug Hamilton. Id. at 1. This deposition was taken several years ago in connection with another case. Id. at 2. Defendants move to strike Exhibit 68 on grounds that Porter, in violation of Federal Rule of Civil Procedure 26(a), "had not disclosed Mr. Hamilton as a witness in this case nor did he identify Mr. Hamilton's deposition as evidence to be used to support his claims." Id. at 1. Rather, Defendants assert that Porter first introduced the exhibit over their objections during the deposition of Defendants' expert, Jeff Noble. Id.
Defendants argue that Porter's failure to comply with Rule 26(a) requires this Court to strike Exhibit 68 from evidence. Id. at 3. Under Federal Rule of Civil Procedure 26:
[A] party must, without awaiting a discovery request, provide to the other parties:
Fed. R. Civ. P. 26(a)(1)(A). Under Federal Rule of Civil Procedure 37:
Fed. R. Civ. P. 37(c)(1). "The burden is on the potentially sanctioned party to prove harmlessness." R.C. Olmstead, Inc. v. CU Interface, LLC, 606 F.3d 262, 272 (6th Cir. 2010) (citing Roberts v. Galen of Va., Inc., 325 F.3d 776, 782 (6th Cir. 2003)). "In fact, `[t]he Sixth Circuit has interpreted the Rule 37(c)(1) exclusionary sanctions to be automatic and mandatory after a violation of Rule 26(a).'" State Auto. Prop. & Cas. Co. v. There is Hope Cmty. Church, No. 4:11CV-149-JHM, 2014 WL 2003302, at *5 (W.D. Ky. May 15, 2014) (citing Chavez v. Waterford School Dist., No. 09-12336, 2010 WL 3975314, at *2 (E.D. Mich. Oct. 8, 2010)).
Porter did not respond to Defendants' motion to strike. Given the automatic and mandatory nature of the Rule 37(c)(1) sanction absent proof of justification or harmlessness, and seeing no such proof from Porter, the Court will grant Defendants' motion.
The motion of Defendants Louisville Jefferson County Metro Government, City of Louisville, Gary Kearney, Lawrence Zehnder, and Gene Sherrard to strike and exclude from evidence Exhibit 68 to Kerry Porter's response to the Defendants' motion for summary judgment is
