Opinion for the Court filed by Senior Circuit Judge WILLIAMS.
When the District of Columbia Council was considering revisions to the District’s alcoholic beverage laws, then-Council Member (now Mayor) Adrian Fenty, who represented Ward 4, proposed a ward-wide four-year moratorium on the sale of single containers of beer — specifically, a rule bаrring retailers from breaking manufacturers’ packages of multiple containers of beer and selling a single container of 70 ounces or less. The underlying idea wаs that such sales were especially likely to *362 lead to public drunkenness and other antisocial behavior.
On the first reading, April 20, 2004, the Council considered and rejected the proposed amendment. At the “second reading,” on May 18, Member Fenty proposed a more “targeted” version of the moratorium, banning singles sales in what one might call a gerrymandered zone within Ward 4 — a zone thаt in fact encompassed all existing Ward 4 Class A and Class B liquor licensees. Singles sales would remain permissible outside the moratorium zone, and licensees could transfer their licenses to areas outside the zone.
At the May 18 hearing a Council member objected that Fenty’s revision constituted a substantial change in his earlier amendment, so that immediate passage would run afoul of the Home Rule Act’s requirement that “[e]ach proposed act ... shall be read twice in substantially the sаme form, with at least 13 days intervening between each reading.” See D.C.Code § l-204.12(a). The Council chair overruled the objection, and the Council approved thе revised amendment by a vote of 11-2. The Council passed the entire bill on May 19 and, after considering and approving further amendments, did so again on June 1. Following exрiration of the Congressional review period, the Omnibus Alcoholic Beverage Amendment Act of 2004, D.C. Law 15-187, 51 D.C.Reg. 6525-55 (July 2, 2004), including the targeted Ward 4 moratorium, codified as amended at D.C.Code § 25-341 (2004), went into effect.
Plaintiffs, who hold liquor licenses in Ward 4, sued in district court claiming that the ban violated the Home Rule Act’s “two readings” requirement, plus several provi-' sions of the federal Constitution. The district court granted plaintiffs’ motion for a temporary restraining order on the day they filed suit, November 12, 2004, and issued a preliminary injunсtion on December 22. On June 16, 2005, the district court granted plaintiffs’ motion for summary judgment with respect to the alleged violation of the Home Rule Act; in light of that ruling it dismissed the fedеral claims as moot.
A federal court has jurisdiction over substantial federal claims, together with local law claims that are part of a common nucleus of operative fact. But a federal court lacks jurisdiction altogether if the federal claims are insubstantial. Finding that to be the case here, we vaсate the district court’s judgment and order the district court to dismiss the local law claim without prejudice.

The defendants did not argue to the district court that plaintiffs’ federal claims were insubstantial. They do raise that argument here, however, and as the question is essential for our and the district court’s subject-matter jurisdiction, there is no wаiver; indeed, we would have to address it on our own motion if they had failed to do so.
Citizens for the Abatement of Aircraft Noise, Inc. v. Metropolitan Washington Airports Authority,
When federal and local claims all derive from a common nucleus of operative fact, the claims constitute a single case or controversy within the constitutional and statutory jurisdiction of the federal courts. See
Exxon Mobil Corp. v. Allapattah Services, Inc.,
A necessary condition for the exercise of supplemental jurisdiction is the substantiality of the federal claims.
Gibbs,
At oral argument we asked plaintiffs’ counsel what they viewed as their most substantial claim, and he pointed to the argument that the District violated the Fifth Amendment’s Due Process Clause by denying the affected licensees individualized notice and an opportunity to be heard. The Supreme Court’s decision in
Bi-Metallic Investment Co. v. State Board of Equalization,
Plaintiffs also allege a violation of the substantive component of the Fifth Amendment’s Due Process Clause. We have recently held that “substantive due process constrains only egregious government misconduct.”
George Washington University v. District of Columbia,
Next is plaintiffs’ theory that the moratorium violates the equal protection component of the Fifth Amendment’s Due Process Clause because the moratorium covers only Ward 4 liquor stores — and none elsewhere in the District. See
Bolling v. Sharpe,
Fourth, plaintiffs allege that the moratorium effects an unconstitutional taking under the Fifth Amendment. But in
Mugler v. Kansas,
Finally, plaintiffs assert that the stаtute is void for vagueness. Outside of the First Amendment context, a plaintiff must show that the law in question “is impermissibly vague in all of its applications.”
Village of Hoffman Estates v. Flipside, Hoffman Estates, Inc.,
In light of the insubstantiality of plaintiffs’ fеderal claims, we conclude that the district court lacked federal-question jurisdiction over those claims and thus supplemental jurisdiction over the Home Rule Act claim. Therefore, we reverse the judgment of the court and remand with instructions to dismiss plaintiffs’ local law claim without prejudice.
So ordered.
