Del. R. Evid. 405
D.R.E. 405 tracks F.R.E. 405. The words "or by testimony in the form of an opinion" were originally omitted from D.R.E. 405(a) but were added in 2001 to conform D.R.E. 405(a) with existing Delaware practice.
For prior Delaware cases illustrating the law covered by D.R.E. 405(a), see Spain v. Rossiter, Del. Super., 120 A. 746 (1923) and State v. Naylor, Del. Super., 90 A. 880 (1914).
For prior Delaware case illustrating the law covered by D.R.E. 405(b), see Robinson v. Burton, Del. Super., 5 Del. 335 (1851).
D.R.E. 405 was amended in 2017 in response to the 2011 restyling of the Federal Rules of Evidence. The amendment is intended to be stylistic only. There is no intent to change any result in ruling on evidence admissibility.
