Associated Press - ATLANTA—A federal appeals court's decision Friday effectively blocked Florida Republican gubernatorial candidate Bill McCollum's attempt to get the state to subsidize his campaign for every dollar beyond $24.9 million spent by his self-financed opponent.

The 11th Circuit Court of Appeals in Atlanta issued a preliminary injunction to keep the state of Florida from releasing the excess subsidy to Mr. McCollum.

The Florida Legislature in 1991 passed a statute enacting a $500 limit on individual campaign contributions and also provided that a candidate would receive public financing if an opponent chose not to follow the state's campaign-finance limits.

Mr. McCollum's opponent, multimillionaire Rick Scott, is self-funding most of his campaign. Under Florida law, he is allowed to put up to $24.9 million into his own campaign. But for every dollar he puts in beyond that, the state provides a matching dollar for Mr. McCollum.

Mr. Scott argued that violates his First Amendment right to free speech.

U.S. District Court Judge Robert Hinkle in Tallahassee on July 14 rejected Mr. Scott's attempt to block McCollum from receiving state funds for his campaign. Judge Hinkle said Florida's election statute was designed to encourage voter participation and avoid the appearance of corruption. He said he didn't want to override it less than six weeks before the state's Aug. 24 primary.

But Judge Hinkle noted at the time that his decision was a close one on its merits and said it could be reviewed differently by judges in other courts.

The 11th Circuit noted Florida's justification of excessive spending because of an anti-corruption interest, but concluded that the state "cannot satisfy its burden of establishing that its subsidy furthers that interest in the least restrictive manner possible.''

"It is disappointing Rick Scott keeps trying to change the rules in the middle of an election despite pledging to abide by them,'' McCollum campaign manager Matt Williams said. "Ultimately, the decision will be left up to the Department of State, but our campaign is reviewing our legal options.''

Mr. Scott's campaign applauded the decision. "Today's ruling protecting Rick Scott's constitutional rights is a huge victory for Florida taxpayers,'' the campaign said in a statement. "In fact today the court limited Bill McCollum's pickpocketing of taxpayers to millions of dollars instead of tens of millions of dollars.''

Mr. McCollum decided 14 months ago to surrender a second term as attorney general to seek the gubernatorial nomination. He was seen as a prohibitive favorite to win the Republican nomination before Mr. Scott emerged from the private sector in mid-April to overhaul McCollum in the polls with a 24-7 statewide advertising blitz introducing himself to voters.

Mr. McCollum's fund-raising has dried up as polls show his upstart opponent passing him up.

"Regardless of the outcome of this case, we remain very confident we will have the resources necessary to communicate Bill McCollum's solid conservative record of leadership and his vision for Florida's future with voters across the state,'' Mr. Williams said.
