John Marshall,
Patterson v. Jenks — Opinion of the Court
“ However these laws may be construed, it is, we think, obvious, that the office was not opened for lands situated within the Indian hunting grounds, and that grants for them were not authorized.But is the whole grant a nullity because it contains some land not grantable?In the nature of the thing, we perceive no reason why the grant should not be good for land which it might lawfully pass, and void as to that part of the tract for the granting of which the office had not been opened. It is every day's practice to make grants for lands, which have in fact been granted to others. ”
