Footnotes

  1. 1 The two motions are materially identical with respect to, inter alia, whether Plaintiff had a duty to preserve. See Dkt. No. 164 in -352 case at 4-7; compare Dkt. No. 118 in -397 case at 4-7. Because the Court has already determined under these facts that Plaintiff did not have such a duty (See Dkt. No. 299 in -352 case at 3-4), any subsequent differences in the motions with respect to (for example) prejudice to Defendants are irrelevant given that the prerequisite element of duty has not been met.
