Amanda Bynes -- Shut Down in Court ...The Conservatorship Stands

Amanda Bynes just got shut down in court ... and her parents' conservatorship is still in place. The problem is ... they can't control her.

Amanda said she was going to Ventura Court Friday to wage legal war to end the conservatorship ... but the last we saw of her was in Hollywood during lunchtime where she was munching on watermelon.

A lawyer claiming to rep Amanda showed up, but the judge ruled she could not hire him because under the conservatorship she lacked capacity to enter into a binding contract. So the hearing ended even before it began, and the conservatorship stays in place.

Here's the problem. Amanda is roaming the streets of Hollywood and clearly delusional. She has intense dislike for her parents, so they can't control or influence her conduct. It seems it's only a matter of time before she hurts herself or others.
