Each sense below has its own examples, sources, and questions.
Examples3
Indictment Names Wrong Date
Prosecutors charged Vanessa Vega with theft on March 15. At trial the evidence showed the taking occurred on March 22. The defense moved to dismiss, arguing the date discrepancy misled preparation. The court denied the motion because the variance did not affect Vega's substantial rights. She had full notice of the transaction and suffered no prejudice in mounting her defense.
Conspiracy Proof Shows Separate Schemes
The indictment alleged one overarching conspiracy among several defendants. Trial evidence instead revealed multiple independent schemes sharing only a common middleman. The variance between the single-conspiracy charge and the proof of separate conspiracies did not affect substantial rights because each defendant received adequate notice and the jury instructions prevented spillover prejudice.
Kotteakos v. United States328 U.S. 750, 764–65 (1946)
Statistical Model Measures Outcome Variance
In a capital sentencing challenge, statistical evidence showed racial disparities in death-penalty outcomes. The model produced an r-squared value indicating it explained less than half the variance in sentencing decisions. The court treated the unexplained variance as fatal to the claim that race impermissibly influenced any particular verdict, because the model could not isolate the effect on the defendant's case.

Frequently Asked2
When does a variance between indictment and proof require reversal?+
Reversal is required only when the variance deprives the defendant of fair notice of the charges or exposes the defendant to double-jeopardy risk. Under Rule 52(a) any variance that does not affect substantial rights must be disregarded.
Supporting sources
Is a fatal variance the same as a constructive amendment?+
No. A fatal variance misleads the defendant or risks double jeopardy but does not change the crime charged. A constructive amendment alters the essential elements so the defendant may be convicted of an offense the grand jury never approved.

Odd-Shaped Lot Needs Setback Relief
Victoria Vernon owns a triangular corner lot whose shape prevents construction of a code-compliant garage. She applies for a variance from the side-yard setback. The zoning board finds the lot's unique configuration creates unnecessary hardship not shared by neighboring rectangular parcels and grants the variance subject to landscaping conditions that protect the neighborhood character.
Landmark Owner Seeks Height Variance
Penn Central owns Grand Central Terminal, designated a landmark. Strict height limits prevent construction above the terminal. The company applies for a variance allowing additional floors to generate reasonable return. The landmarks commission denies the variance after finding the terminal already earns a reasonable return under existing restrictions, preserving the public interest in historic preservation.
Penn Central Transportation Co. et al. v. New York City438 U.S. 104, 98 S.Ct. 2646, 57 L.Ed.2d 631 (1978)
A state statute banned contraceptive counseling for married couples. Challengers argued the law varied from constitutional concepts of liberty by intruding on marital privacy. The Court held that the statute's breadth created an impermissible variance with protected zones of personal autonomy, rendering the prohibition unconstitutional even though no explicit textual right addressed contraception.
Griswold v. Connecticut381 U.S. 479 (1965)
Frequently Asked3
What must an applicant prove to obtain a zoning variance?+
The applicant must show that the zoning ordinance imposes unique hardship on the particular parcel because of its special characteristics and that the variance will not be contrary to the public welfare or the comprehensive plan.
Supporting sources
How does a variance differ from a special exception?+
A variance grants relief from a literal restriction when hardship exists. A special exception permits a use expressly authorized by the ordinance only upon satisfaction of stated conditions. It is not a relaxation of the ordinance itself.
Can a variance be granted when the hardship is self-created?+
No. Most jurisdictions refuse a variance when the owner created the hardship, because the owner cannot claim the ordinance imposes unnecessary hardship that the owner brought upon the property.

…from constructing a 55-story office building above the terminal. Moreover, the law permits the owner of a landmark to obtain a variance if the landmark cannot earn a reasonable return on its investment. Appellants have not applied for such a variance. They have not shown that the terminal cannot earn a reasonable…
