That decision came Wednesday afternoon after a two day bench trial in Wayne County.
The judge however, convicted Wiles' son, Joe, on a single count of animal cruelty.
The charge was the result of the way in which Joe Wiles transported piglets to and from the family's farm in Creston. Wiles will have to pay a $200 fine, and received a year's probation.
The judge also ruled that there wasn't enough evidence against Joe Wiles on three other counts of animal cruelty and cleared him on those remaining charges.
The judge cleared Dusty Stroud, a farmhand at the Creston farm, on a charge of animal cruelty. Stroud could be seen on undercover video hanging a hog to its death.
The case drew much attention both in Wayne County and with animal rights activists from around the country.
The Humane Farming Association sent an undercover investigator to the farm to videotape the treatment of the hogs on the farm. The president of the HFA says the group is relieved the special prosecutor in the case was able to get at least one conviction.
The judge said while he found the video of the hog being hanged offensive, there is no existing case law on the books in Ohio which makes the practice illegal.
The HFA says it will continue the work to make the practice illegal in Wayne County as well as every other county across the country.
Channel 3's Bill Safos first broke the story in November 2006.
