This from HSUS Oregon state director Scott Beckstead:
RULING TODAY BY THE OREGON COURT OF APPEALS: The Oregon Court of
Appeals has ruled that the emergency aid exception to the search and
seizure warrant requirement applies to animals. This is a case that
originated in Douglas County, Oregon, and involved Grace, the little
brown mare who became a worldwide celebrity for her will to survive
after being horribly abused. Combined with the ruling in State v. Nix,
which held that individual animals are crime victims just like people, I
must say Oregon courts are definitely moving in the right direction....
The case is State v. Fessenden.
