*710 ORDER AND JUDGMENT *

Marc Rubat du Merac was a graduate student and research assistant at the Colorado School of Mines when a female undergraduate filed a grievance with the school alleging that he had sexually harassed her. In turn, Mr. du Merac submitted his own grievance asserting that the allegations were false and for several months the school investigated the competing complaints. While the school’s investigation was ongoing, Mr. du Merac contacted various witnesses on his own initiative, sending them copies of each grievance along with excerpts from Colorado’s criminal libel statute and a suggestion that “any person [who] aids or abets a person [who] is engaged in criminal libel could be considered [an] accessory to this felony.” In the end, the school’s investigation determined that the undergraduate’s complaint was meritorious, that Mr. du Merac’s was not, and that Mr. du Merac’s contact with witnesses constituted retaliation for a meritorious complaint. As a consequence of its findings, the school suspended Mr. du Merac for fifteen months, a result that, in turn, spelled the loss of his funded research position.

For his part, Mr. du Merac replied at this point with a lawsuit under both state and federal law, one alleging that the school had engaged in reverse sex discrimination. But at summary judgment the district court concluded that Mr. du Merac hadn’t shown either a prima facie case of discrimination or that the school’s proffered reasons for the suspension were pre-textual. Now on appeal and proceeding pro se, Mr. du Merac insists that the district court erred and that the district court judge colluded with the school and is biased against him. He also levels before us a host of additional claims that he never presented to the district court.

Having carefully examined the briefs, record, and applicable law — and construing his pro se arguments as liberally as we might — we are unable to discern any reversible error in the district court’s decision and so adopt it as our' own. Further, Mr. du Merac’s allegations of collusion between the district court judge and the school are unsubstantiated on the record we have. See Liteky v. United States, 510 U.S. 540, 555-56, 114 S.Ct. 1147, 127 L.Ed.2d 474 (1994). And his various new claims — alleging violations of the First Amendment, the Due Process Clause, the Colorado State Employee Protection Act, the Family Educational Rights and Privacy Act, and the Higher Education Opportunity Act, along with various administrative and contract violations — are not properly before this court. See Tele-Commc’ns, Inc. v. C.I.R., 12 F.3d 1005, 1007 (10th Cir. 1993). Accordingly, the district court’s decision is affirmed and the appeal is dismissed.
