Should the person who provides beer to teenagers for a party be liable when one of the teenagers hurts another during the party?

The Washington Court of Appeals has decided an interesting case that asks whether civil liability should be imposed upon those who plan and furnish beer for a high school graduation keg party where criminal violence erupts. The appellant was the mother of a boy who died as a result of being assaulted at the party. She argued that the assault was a foreseeable result of providing unlimited beer to teenagers in a remote location without supervision. The Court, however, found that the trial court did not err in dismissing the case on summary judgment. The opinion is available here. Thanks to the Legal Profession Blog for the tip.
