)' LIVE ANIMALS can now be used in New Jersey high school biology experiments with the full sanction of the court. Essex County Court Judge Charles S. Barrett Jr., ruled in favor of animal experimentation in a landmark decision that is expected to have broad impact on education, not only in New Jersey but throughout the nation. His opinion sets a precedent for the legal interpretation of "animal crueltv." "Cruelty to my mind is the unjustifiable infliction of pain with the act having some malevolent or mischievous motive. There must be something willful or wanton about it," he wrote in his decision.
