The Legally Blonde star applied for an emergency conservatorship in Davidson County, Tennessee last month (May12) after her mother Mary Elizabeth sued her dad, Dr. John Witherspoon, for bigamy.
Mary Elizabeth, known as Betty, claims her estranged husband exchanged vows with Tricianne Taylor in January (12) while he was still legally married to her. The actress' mum is seeking to have the latest union annulled, although she insists she does not want a divorce.
John, 70, reportedly suffers from depression and the early stages of dementia and movie star Witherspoon and her brother filed a petition to take over the management of their dad's affairs.
However, lawyers for both parties agreed the case was no longer considered an emergency and Circuit Judge Randy Kennedy dismissed the request on Monday (25Jun12).
The judge also upheld a previous ruling to seal all records in the case and bar the media from the hearings.
Meanwhile, Betty Witherspoon obtained a temporary restraining order against Taylor, banning her from using the last name of Witherspoon.
