A judge has tentatively ruled against Katherine Jackson in her request for a new trial against concert promoter AEG Live.
On Friday, Los Angeles Superior Court Judge Yvette Palazuelos ruled against Jackson but did not immediately finalize her ruling, Billboard is reporting.
Her lawyers later argued that an error had been made in juror instructions and there should be a new trial.
Judge Palazuelos did not say when she would finalize her ruling which came after she heard two hours of legal arguments.
If her decision stands, Jackson could still appeal to a higher court.
