Samuel Gibson and Rafeal Wofford were convicted of unlawfully distributing heroin in violation of 21 U.S.C. § 841(a)(1). We have affirmed Wofford’s conviction.
United States
v.
Wofford,
We must first determine whether we have jurisdiction to consider the appeal.
Stewart v. Bishop,
F.R.A.P. 4(b) requires that in a criminal case a notice of appeal shall be filed in the District Court within ten days after the entry of judgment. The District Court may extend this time for a period not to exceed thirty days if the defendant shows excusable neglect. Taking an appeal within the prescribed time is mandatory and jurisdictional.
United States
v.
June,
Although the affidavit accompanying Gibson’s motion for leave to appeal in forma pauperis was sufficient to constitute notice of appeal,
see
F.R.A.P. 3(c);
Alley v. Dodge Hotel,
Gibson’s arguments regarding improper joinder and severance are adequately answered in United States v. Wofford, supra at 585-586.
Gibson’s next argument, that certain impeachment evidence was improperly excluded, also lacks merit. Gibson wanted to inquire into the federal regulations governing the methadone program since the witness’s use of methadone indicated a lack of compliance with the regulations. This was clearly a collateral matter and it was within the discretion of the trial court to foreclose inquiry into it.
See
Fed.R.Evid. 403;
United States v. Johnson,
The judgment of conviction is affirmed.
