Jermaine Jackson has called for an end to the public feud that has embroiled his family for more than a week, saying issues over the care of his mother and with late brother Michael's estate should be handled privately.
Jackson wrote in a statement that he regrets the public turmoil that resulted from his mother Katherine's 10-day trip to an Arizona spa.
The trip sparked a missing persons report and a driveway confrontation between relatives at Mrs Jackson's home before a judge stripped her of guardianship duties regarding Michael's three children.
"Mistakes have been made and irrational things have been said on both sides in a highly charged emotional environment," Jermaine Jackson wrote. "It is time for us all to draw a line in the sand and move towards peace, co-operation, love and healing."
The family is still raw from the death of the pop superstar three years ago, Jackson wrote, and his mother has endured incredible stress and pressures since then.
He said he remains concerned about his brother's estate but is dropping support for a letter leaked two weeks ago that called on executors of the estate to resign. Jackson said his statement was prompted after his son asked if he could no longer visit Mrs Jackson at her suburban Calabasas home.
"After much soul-searching, it is clearly time for us to live by Michael's words about love not war," Jackson wrote.
At the request of TJ Jackson, temporary guardian of Michael's children, the estate has acknowledged it has blocked certain relatives from visiting the home. The relatives were not named.
Lawyers are still trying to untangle some of the issues that the family dispute has created. Mrs Jackson's lawyer, Perry Sanders Jr, said lawyers will return to court tomorrow to present an agreement to restore his client as a guardian.
The agreement would also call for TJ Jackson to remain a co-guardian, with control over the staff and day-to-day operations of the home where Mrs Jackson and her grandchildren, Prince, Paris and Blanket, currently live.
