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.

“[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).
