A court official says the judge handling Lindsay Lohan's criminal case plans to issue an unspecified ruling in the case a day before her attorneys are due in court.

Los Angeles Superior Court spokesman Allan Parachini said Monday that Judge Elden Fox plans to issue the ruling Tuesday afternoon. Parachini said he had no additional details.

Lohan is currently serving a 90-day sentence in a rehabilitation program, but there have been unconfirmed reports that she will be released early.

Lohan spent 14 days in jail and was taken to rehab on Aug. 2 after another judge determined she violated her probation in a 2007 drug case.

A prosecutor and Lohan's attorney are due in court for a hearing Wednesday.
