How do you justify the proclamation of 1763? ?

The proclamation of 1763, which so inflamed colonists and would eventually weighed as one more element into the decission of the American Revolution was apparently justifiable from the English standpoint as to a means of limiting the wars with the Native American tribes through the decission of forbidding colonists to establish themselves in the lands they had fought for.

imma say false because i dont know anything about this.
