The Ground Game Act 1880 (43 & 44 Vict.) is a law that was passed by the British Parliament in 1880 AD by Gladstone's government.
There were many complaints over many decades about the intolerable amount of damage that farmers' crops were suffering from damage by wild rabbits and hares and landowners not allowing farmland occupiers to kill them because of game preservation.
This law gives land occupiers the unalienable right to kill rabbits and hares on the land which they occupy.
