At issue was the scope of the Fifth Amendment, which allows governments to take private property through eminent domain if the land is for "public use."

Susette Kelo and several other homeowners in a working-class neighborhood in New London, Conn., filed suit after city officials announced plans to raze their homes for a riverfront hotel, health club and offices.

New London officials countered that the private development plans served a public purpose of boosting economic growth that outweighed the homeowners' property rights, even if the area wasn't blighted.

Justice  Sandra Day O'Connor, who has been a key swing vote on many cases before the court, issued a stinging dissent. She argued that cities should not have unlimited authority to uproot families, even if they are provided compensation, simply to accommodate wealthy developers.

The lower courts had been divided on the issue, with many allowing a taking only if it eliminates blight.

"Any property may now be taken for the benefit of another private party, but the fallout from this decision will not be random," O'Connor wrote. "The beneficiaries are likely to be those citizens with disproportionate influence and power in the political process, including large corporations and development firms."

She was joined in her opinion by Chief Justice William H. Rehnquist, as well as Justices  Antonin Scalia and  Clarence Thomas.

Nationwide, more than 10,000 properties were threatened or condemned in recent years, according to the Institute for Justice, a Washington public interest law firm representing the New London homeowners.

New London, a town of less than 26,000, once was a center of the whaling industry and later became a manufacturing hub. More recently the city has suffered the kind of economic woes afflicting urban areas across the country, with losses of residents and jobs.

The New London neighborhood that will be swept away includes Victorian-era houses and small businesses that in some instances have been owned by several generations of families. Among the New London residents in the case is a couple in their 80s who have lived in the same home for more than 50 years.

City officials envision a commercial development that would attract tourists to the Thames riverfront, complementing an adjoining Pfizer Corp. research center and a proposed Coast Guard museum.

New London was backed in its appeal by the National League of Cities, which argued that a city's eminent domain power was critical to spurring urban renewal with development projects such Baltimore's Inner Harbor and Kansas City's Kansas Speedway.

Under the ruling, residents still will be entitled to "just compensation" for their homes as provided under the Fifth Amendment. However, Kelo and the other homeowners had refused to move at any price, calling it an unjustified taking of their property.

The case is Kelo et al v. City of New London, 04-108.
