IN THE UNITED STATES COURT OF APPEALS FOR THE FIFTH CIRCUIT United States Court of Appeals Fifth Circuit FILED December 21, 2007 No. 07-50819 Charles R. Fulbruge III Summary Calendar Clerk RICHARD ARIZPE, Plaintiff-Appellant, v. MARY E. PETERS, Secretary, United States Department of Transportation, Federal Aviation Administration; CARI M. DOMINGUEZ, Chairwoman, United States Equal Employment Opportunity Commission, Defendants-Appellees. Appeal from the United States District Court for the Western District of Texas No. 5:06-CV-563  No. 07-50819 Before REAVLEY, SMITH, and BARKSDALE, Circuit Judges. PER CURIAM:* Richard Arizpe sued under title VII and the Age Discrimination in Em- ployment Act. As the magistrate judge stated, [Plaintiff] is obviously upset with the circumstances surrounding his employment with defendant, as evidenced by the lawsuits he filed in 1998 and 2002 against the Department of Transportation and Federal Aviation Administration [footnote omitted]. Plaintiff’s con- clusory allegations and legal conclusions masquerading as factual conclusions, however, cannot suffice to prevent defendant’s motion to dismiss in this case. After reviewing the briefs and pertinent parts of the record and the applic- able law, we affirm, essentially for the reasons stated by the magistrate judge in her comprehensive Report and Recommendation signed on January 12, 2007. We also conclude that Arizpe’s argument that the district court’s ruling is legally invalid because it listed Maria Cino as Acting Secretary of Transportation, rath- er than Mary Peters as Secretary of Transportation, is frivolous. See FED. R. CIV. P. 25(d) (“[A]ny misnomer not affecting the parties’ substantial rights must be disregarded.”). Arizpe’s other arguments are equally unavailing. AFFIRMED. * Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5TH CIR. R. 47.5.4. 2
