FORT LAUDERDALE, Fla. (AP) - A Broward County judge is mulling over a law firm's challenge to the validity of Florida Attorney General Bill McCollum's investigation into foreclosure practices.

Attorneys for the Law Offices of David J. Stern claimed Tuesday that the attorney general's office has no authority to investigate. State lawyers contend they have authority in their role as consumer advocates.

Circuit Judge Eileen O'Connor said she would rule soon. A Palm Beach County judge previously voided an attorney general's subpoena for another foreclosure law firm. McCollum's office asked the judge to reconsider that ruling.

The investigation involves alleged fraud and false paperwork filings by four law firms in thousands of foreclosure cases.
