The court ruling means Whitney's sister-in-law and Bobby will now share responsibility for 22-year-old Bobbi Kristina's medical care. Bobby filed a petition last month to become her legal guardian.
The court also appointed an attorney -- Bedelia Hargrove -- as conservator, and she will control all financial and legal matters for Bobbi Kristina ... who is now breathing on her own. Whitney's family points out she's suffered "global and irreversible brain damage."
We got video of Pat and Cissy Houston leaving the DeKalb Co. courthouse after Thursday's hearing, and Pat told us, "It was a good day."
