A New Jersey judge who allowed a lawyer to plug an evidentiary gap with a Wikipedia page has been reversed on the ground that the online encyclopedia that “anyone can edit” is not a reliable source of information.
As stated in the ruling of Palisades Collection, L.L.C. v. Graubard, No. L-3394-06, 2009 WL 1025176 (N.J. Super. A.D. April 17, 2009),
[I]t is entirely possible for a party in litigation to alter a Wikipedia article, print the “article and thereafter offer it in support of any given position,” an appeals court held. “Such a malleable source of information is inherently unreliable and clearly not one ‘whose accuracy cannot reasonably be questioned,” such as would support judicial notice under New Jersey Evidence Rule 201(b)(3).
