" �Counsel for complainant have insisted in argument that the decis- ions of the commission are of no higher character than those of the officers of the land department, which may be set aside by a court of competent jurisdiction, on the ground of fraud, mistake, or miscon- struction of the law.

There is a broad distinc- tion between its functions and those of the officers of the other branch of the executive departments referred to.

The language of the act and the surround- ing history and oircumstances alike forbid such an interpretation. It was time to have an end to controversy. For half a century the courts and legislatures of states and nation have been vexed with this dispute, The questions of title have been finally settled. Congress resolved through the commission to have a final settlement of all questions as to improvements aud the right to purchase the title; and 80 it was provided that the commission should "finally deter- mine" these questions. This language, when applied to a special tribunal, must be held to mean a final determination in the absolute sense, although similar language, if applied to officers of the land department, might be final only so far as departmental action is con- cerned.
