The Wind in the Willows (1984)

The weasels buy the part of the Wild Wood upon which stands the entrance to Badger's home. They order Badger to vacate the property. When Badger takes the weasels to court, the judge decides in their favour, as the weasels' deed to the property appears to be valid. It is mole who saves the day when he discovers a Roman document signed by Julius Caesar which conveys the ownership of the area that is now the Wild Wood to the badgers and their descendants. With this document in hand, Badger is able to chase the weasels away only minutes before they take permanent possession of his burrow.
