The largest implication of the case was the establishment of Congressional "plenary power." This concept gave Congress "full" power in being able to abrogate and abandon the treaties negotiated with Native American tribes. The court essentially gave the "green light" to Congress in being able to annex Native American lands and territories. While the treaties negotiated with Native Americans helped to provide some level of comfort and security that would stop expansion upon their territories. In the Lone Wolf case, the Court rendered a decision that would allow Westward Expansion to become synonymous with overtaking Native American territories. The Court also argued that the concept of "Native American" lands was an illusory one in that the territories were "wards of the nation," helping to bring out the idea that expansion was inevitably going to "help" Native Americans, as opposed to protecting any sense of their autonomy.
