In a decision that set new precedent, the U.S. Court of Appeals for the Third Circuit has revived T-Mobile’s challenge to a zoning decision that barred the company from building a cell tower in Wilmington, ruling that T-Mobile’s attempt to correct a prematurely filed lawsuit was enough to allow the case to proceed in Delaware federal court.

A three-judge panel of the appeals court Thursday reversed a Delaware district court ruling, which held that T-Mobile Northeast’s complaint was unripe because it was filed before the Wilmington Zoning Board of Adjustment issued a written decision blocking the company’s request to build a cell tower on top of the Claymore Senior Center.
