That BBC article is rather poorly related to the topic. A precedent needs to be a court document.

The first case. The owner of a sick pig buried on his land, then another person dig it and sold the carcass, in the 19th century. It's hard to tell if he was prosecuted for digging the land, or selling a diseased carcass, or theft.

The tesco case is equally poor. It doesn't say what is the result of the trial. Most likely because there wasn't one or it didn't go the way the article wished.
