"We did not believe that there was any basis for the court to extend jurisdiction in this matter, because the First District Court of Appeal's decision was in full compliance with the laws of Florida," he added.

Mr. McCarty had suspended Allstate's ability to write new business after he issued a subpoena for company documents and decided that the insurer was not acting in good faith to supply the material he requested. Allstate maintained that it had supplied as much documentation as it could, but that it was prevented from supplying some documents that were privileged and involved trade secrets.

A state appellate court upheld Mr. McCarty's ruling, although he later lifted the suspension when Allstate provided an affidavit that it had fulfilled the document request to the best of its ability.

In declining to take the case any further, Mr. McCarty said the court upheld the notion that the OIR should be free to obtain any documents it requires from insurance companies.

"The Supreme Court's decision reassures Floridians that the office has full access to insurers' books and records and upholds the office's actions in its efforts to protect consumers," he said.

Kathy Thomas, a spokesperson for Allstate in Florida, said, "We have reviewed the Supreme Court's ruling and will abide by its decision."
