(appeal of claims dismissed against landlord defendants arising from automobile versus horse incident decided under state Equine Activity Liability Act (EALA); decedent was killed when she struck a horse that had escaped from a local stable; court upheld dismissal of plaintiff’s claim against defendants under EALA because no private right of action created by statute; court also upheld dismissal of negligence claims against landlords because horse was under control of tenant, so no duty existed; court did, however, remand the case for determination of a nuisance claim; plaintiff presented evidence of at least 30 incidents in which animals escaped from the property and about which defendants were aware).
