Lindsay Lohan walked out of the Los Angeles County women's jail in Lynwood late Friday night, capping an unusual day of legal twists in which one judge overturned another's decision to jail the actress without bail on a probation violation.

The 24-year-old star of "Freaky Friday" and "Mean Girls" was processed out of the Century Regional Detention Facility about 11:40 p.m. Friday after posting $300,000 bail. She was whisked out of a back door and driven to an undisclosed location.

Beverly Hills Judge Elden Fox had ordered Lohan jailed without bail until a hearing Oct. 22 on whether Lohan should be incarcerated for twice using drugs in violation of her probation on a drunk-driving conviction. She was Twice convicted on DWI in 2007.

It also appeared to be an effective way to skirt Los Angeles County's early release policy and keep Lohan incarcerated for a month. The actress has twice received jail sentences but both times served less time than ordered because of overcrowding at the women's jail. Most female inmates serve a quarter of their sentence.

But the attorney for Lohan, Shawn Chapman Holley, immediately challenged the legality of holding her client without bail based on a probation violation for a misdemeanor.

So, she successfully shopped for another judge in Los Angeles County Superior Court Judge Patricia M. Schnegg sided with Chapman Holley's argument that under California law, a misdemeanor defendant is entitled to bail and about 6 p.m. signed the order granting a writ of habeas corpus.

But in posting bail, Lohan must agree to conditions, including wearing a SCRAM alcohol and drug detection device, refraining from being in areas where alcohol or drugs are being consumed, and be subject to immediate search by law enforcement.
