From what I recall, his position was that his family had been using that land for grazing from well before the BLM was even created.
The BLM was established in 1946, the same year Clive Bundy was born. The Bundy family actually lives in Las Vegas. Clive’s father, David, purchased the land in 1949, and started paying the fees to graze from 1954 to 1993 when Clive didn’t renew his permit. Clive Bundy was not grazing on his ranch only, he was using federal land also. The initial process was for federal trespass.
