Read the following excerpt from a US court opinion:
```
32.1 and 10th Cir. R. 32.1. 1 . "The Rules of Professional Conduct adopted by the Supreme Court of the State of New Mexico apply except as otherwise provided by local rule or by Court order. See, e.g., D.N.M.LR-Civ. 83.4(c). Lawyers appearing in this District must comply with the section for lawyers of ‘A Creed of Professionalism of the New Mexico Bench and Bar.’" D.N.M.LR-Civ. 83.9. 2 . Mr. Bello asserts in his statement of issues that an attorney's "respectful disagreement” with a district court cannot be a proper basis for discipline. Aplt. Br. at XVI. His brief, however, does not develop this particular argument, and in fact, makes no further reference to this contention. We therefore deem the argument waived. See Dubbs v. Head Start, Inc., 336 F.3d 1194, 1202 n. 4 (10th Cir.2003)
