Efforts by Michael Jackson’s mother and children to pin at least a portion of the blame for the singer’s 2009 death on the promoters of his planned comeback tour will come to a head in a courtroom next week.

Los Angeles County, Calif., Superior Court Judge Yvette Palazuelos was scheduled to consider defense motions for summary judgment on February 25, ahead of an April 2 trial date. Jackson died on June 25, 2009, days before he was scheduled to start the This Is It tour in London. He was 50 years old.
