A Federal judge has ruled in favor of allowing the Humane Society of the United States to join the state in defending Ohio's new law regulating exotic animals.Four animal owners filed a lawsuit contending the restrictions threaten their First Amendment and property rights. The Humane Society argued it has a significant interest in defending the law it strongly supported, as well as an interest in the lawsuit's outcome because the organization is pushing similar laws nationwide. The animal owners say the Humane Society's interests are political, and the group failed to demonstrate how the state wouldn't protect its interests.
