Or he was protecting the "big money" interests at the time ... as the "Georgia Gold Rush" started in 1828, and the case was in 1832 - during the time the US Government was starting the forcible relocation of native tribes out of the area (aka "Trail of Tears").
If Jackson would have followed the SCOTUS ruling ... he would have been obligated to abide by existing treaties between the British and tribes, prior to the Revolution. Which would have meant viewing the tribes as sovereign nations that the US government and State of Georgia had no authority to remove from their land.
To me, it appears Jackson acted out of greed and hatred.
