For the Seventh Circuit Chicago, Illinois 60604 Submitted June 28, 2007 * Decided July 3, 2007

Before Hon. FRANK H. EASTERBROOK, Chief Judge Hon. JOHN L. COFFEY, Circuit Judge Hon. DANIEL A. MANION, Circuit Judge

No. 06-2899 UNITED STATES OF AMERICA, Plaintiff-Appellee ,

v. HARRY E. MILES, Defendant-Appellant

. Appeal from the United States District Court for the Central District of Illinois.

No. 05 CR 40051 Joe Billy McDade, Judge

. O R D E R A jury found Harry Miles guilty of cons piracy to distribute and possess with the intent to distribute cocaine and methamphetamine, 21 U.S.C. §§ 846, 841(a)(1), and possession with intent to distribute cocaine and methamphetamine, id. § 841(a)(1). He was sentenced to a total of 360 months’ imprisonment and five NONPRECEDENTIAL DISPOSITION To be cited only in accordance with Fed. R. App. P. 32.1No. 06-2899 Page 2 years’ supervised release. He appeals, proceeding pro se after representing himself at trial with the help of standby counsel. Miles first argues that the district court lacked subject-matter jurisdiction over his prosecution because, he asserts, the statute authorizing federal district courts to hear criminal cases, 18 U.S.C. § 3231, was not passed by both the House of Representatives and the Senate in the samesession of Congress. Miles’s assertion is incorrect; in fact, the House passed th e bill in the first session of the 80th Congress and the Senate in the second, wi th the House then voting to pass the Senate version. In any event, if the Speaker of the House and the President pro tempore of the Senate attest that a bill has been duly passed, the enrolled-bill rule prevents us from going behind the bill in the manner Miles proposes to evaluate whether the bill satisfied the constitutional requirement that it pass both houses of Congress. Marshall Field & Co. v. Clark , 143 U.S. 649, 672-73 (1892); see Public Citizen v. U.S. District Ct. , 2007 WL 1529482, at *8 (D.C. Cir. May 29, 2007). Once the presiding officer of each chamber certif ies the bill, “its authentication as a bill that has passed Congress should be deemed complete and unimpeachable.” Marshall Field , 143 U.S. at 672. Miles raises another purported jurisdictional defect: he argues that the penalty provisions of 21 U.S.C. § 841 are “not law” because they were “repealed and not properly re-enacted into law.” He cont ends that his convictions must be vacated because a statute that criminalizes conduct without assigning penalties is invalid. Notably, Miles provides no support for his assertion that Public Law 99-570 repealed rather than amended the penalty provisions, and indeed, the amendments to § 841 that he cites, contained in Title I, Subtitle A, of that legislation, do no such thing. SeeNarcotics Penalties and Enforcement Act of 1986, Pub. L. No. 99-570, §§ 1002, 1005, 100 Stat. 3207 (1986). Finally, Miles contends that the district court violated the Speedy Trial Act, 18 U.S.C. §§ 3161-74, by improperly excluding certain days from counting toward the 70 days allotted between indictment and trial. See id . § 3161(c)(1). The government argues that Miles waived this contention by failing to develop it in his opening appellate brief, where the totality of his argument consists of one sentence incorporating by reference a separate memorandum of law located in a 114-page separate appendix. We have counseled lit igants that it is unacceptable to present arguments by way of referring us to a brief or memorandum filed in the district court. Kauthar SDN BHD v. Sternberg , 149 F.3d 659, 668 (7th Cir. 1998); Prudential Ins. Co. v. Sipula , 776 F.2d 157, 161 n.1 (7th Cir. 1985). The practice “unnecessarily confuses and diffuses the issues presented” and often violates the rules limiting the size of appellate briefs. Sipula , 776 F.2d at 161 n.1. Here, Miles’s memorandum is not even a document he filed in the district court (though the argument is identical); it is simply a continuation of his brief camouflaged as anNo. 06-2899 Page 3 “appendix.” Taken together, the documents exceed the word limit for appellate briefs by 1,669 words. This is in spite of the fact that we denied the request that Miles filed in February for permission to file an oversized brief. United States v. Miles , No. 06-2899 (7th Cir. Feb. 5, 2007). Miles flouts our denial of that motion by attempting to incorporate a separate memorandum into his brief, and as a result, he has waived his speedy-trial argument. His attempt to resuscitate the argument by discussing it in his reply brief is unavailing; arguments not developed in the opening brief are waived. E.g., United States v. Alhalabi , 443 F.3d 605, 611 (7th Cir. 2006).

AFFIRMED.
