GAINES, C. J. This is a petition for a mandamus against J. T. Robison, Commissioner of the General Land Office, to compel him to set aside an order canceling the sale of certain lands belonging to the public free school fund, and to reinstate the sales.

The facts averred in the petition are that one Salvador Chavira in 1904 had purchased the lands in controversy from the respondent, and that after a lapse of three years thereafter Chavira filed his affidavit of occupancy of the lands', supported by the affidavit of three disinterested persons, and that thereupon the Commissioner of the General Land Office issued to him a certificate that he had occupied the land for three years as required by law; that thereafter relator, without knowledge of any defect in the title to said lands and for a valuable consideration, bought the lands from said 'Chavira and had them conveyed to him.

The relator also avers the cancellation of the sales made by the Commissioner to the relator, and that the Commissioner had since sold the lands to three different purchasers, and that he had brought suit against each of said purchasers, and had obtained a judgment against each of them for the land. The decision of this court in the case of Logan v. Curry, 95 Tex. 664, 69 S. W. 129, covers this case at every point.

It is held in that case that after the lapse of three years, when the purchaser has made his affidavit of occupancy and improvement, and the Commissioner has issued him a' certificate showing that he has occupied and improved the land as required by the statute, the latter has no power to cancel the sale for failure to occupy the land. So, also, as to the question of collusion.

It is also distinctly held in that case that when the applicant makes the affidavit required of a purchaser, and the Commissioner accepts it and awards the sale, that that action settles the question of collusion, and the Commissioner is without power to. cancel the sale upon that ground. Accordingly the mandamus, as prayed for, is awarded.
